A fairly new technology in South Africa, infrared thermal imaging is the use of expert equipment in order to see the infrared spectrum. Schmidhauser Electrical is one of the few electrical companies in South Africa currently utilising this technology, although it is mandatory in other parts of the world.

Using this new technology, Schmidhauser Electrical can give clients a comprehensive report, allowing them to plan and budget for electrical maintenance. A qualified operator, a Thermographer, can make accurate interpretations of what is happening with your power inside the wall based on the heat signatures. Thermography makes it possible to see one’s environment with or without visible illumination. The current energy crisis in South Africa makes infrared thermal imaging a very appealing option. By detecting heat loss through windows, doors, roofs and poor insulation, a home owner will know where to take steps to reduce this energy loss.

Infrared Thermal Technology, a new technology that could save you moneyFor Schmidhauser Electrical, this new science allows the thermographer to eliminate potentially expensive and dangerous hazards; improvement in machine efficiencies by identifying cooling system inefficiencies; prevention of a fire before it starts, thus saving you money as the annual detection of fire hazards will reduce your insurance premiums. The range of applications is unlimited.

Electricity is an extremely flexible form of energy, and it may be adapted to a huge, and growing, number of uses, it can also be very dangerous, if not used or maintained properly. Infrared Thermal Imaging can give you a comprehensive report about electrical imbalances that lead to high electricity bills and tripping and it is also used to spot and solve other abnormalities.

Trust Schmidhauser Electrical to make sure your ECOC compliant

Legislative changes have made it mandatory for a home owner to be in possession of a valid Electrical Certificate of Compliance (ECOC). With over decades of expertise, Schmidhauser Electrical is your port of call. Since the changes in 2009, home owners have been legally required to provide the ECOC to not only prospective buyers, but to home insurance companies as well. The certificate is proof that the electrical installation is safe. Failure to produce the document could result in the insurance company rejecting the claim, and/or the sale of your property being unsuccessful.

Trust Schmidhauser Electrical to make sure your ECOC compliantBefore 2009, the ECOC remained valid indefinitely and unless changes to the electrical installations were made, could be transferred without limitations. This essentially meant that the seller could provide the buyer with the same certificate they received when they purchased the home, irrespective of how long ago it was when they moved in.

During the sale process, these days there is a need for the conveyance to obtain the original certificate from the seller, before the sale process can begin. If the certificate is older than two, or if any changes have been made to the electrical installations during this time, the seller is required to get a certified electrician to inspect the installations.

The original compliance certificate must eventually be retained by the buyer after it has been presented to the conveyance attorneys, as legislation requires a property owner to produce a valid certificate of compliance on request to an inspector.

Below is a list of what is covered in a compliance certificate and what is not;

YES NO
Distribution board Fixed appliances; examples, stoves, hot water,
Internal circuit breakers Cylinders, under floor heating mats.
Internal wiring Secondary wiring to under floor heating mats
External wiring Extraction fans
Earthing Motors
Earthing of all extraneous metallic parts Ceiling fans
Eg: Hot water cylinders, satellite dishes, aerials. Lighting fixtures
light switches Changing of globes
Plug points Heater towel rails
Isolators examples, cooker units, extraction fans, fan motors Anything fed from a plug top.
Light points (junction and wires that protrude from ceiling) Misuse or tampering of installation.
cable that runs from isolator to a fixed appliance; Bore hole pumps, Speed heats, Extension leads
Eg: from a cooker unit to the appliance Cooker units
Itself. Garage and gate motors
Swimming pool distribution boards Maintenance irregularities
Cable that runs from board to pool light. wiring past the council mains
Pool light point Pool globes
Timers Inaccessible areas – which are noted in bold on
photo cells report and certificate
Transformers; eg: for down lights transformers Energy dispensers

Recently, we at Schmidhauser Electrical were tasked with a multi million rand turnkey project at Cape Town’s Groote Schuur hospital. The project, currently underway, is for the installation of a new linear accelerator bunker suite, which will eventually be used to house a Linac machine which is used for the treatment of cancer patients. To accommodate this new machine an upgrade to the existing electrical supply was required.

Schmidhauser Electrical at Groote Schuur Hospital A project that has presented some challenges, we have managed to stay on top and are still standing. The scope of the work involved, but isn’t limited to; both MV and LV installation work. The MV scope entails the installation of 2 x new 800kVA transformers, 1 x new ring main unit and new MV cables for the ring main; while the LV installation comprises of new main and sub-distribution boards, LV reticulation, power and lighting.

Poaching has reached unprecedented heights. As of the end of Sept 2014, 787 Rhinos have been poached this year alone. 10 years ago, however, the picture was vastly different; a mere 25 rhinos were poached a year. In 2011, the number had increased exponentially, with over 440 rhinos poached, according to stats.

In a bid to curb the assault on our beautiful rhino, My Rhino, through ceramic design and art work, aims to raise funds, create awareness and add colour to the plight of the rhino. Working with a number of talented Southern African artists, My Rhino hosted an auction at Hyde Park Corner on 2nd of October 2014, the proceeds of which will go towards the Endangered Wildlife Trust. Along with sponsors and incredible support from various organisations, including Schmidhauser Electrical, My Rhino hopes that the decor item creates the awareness necessary to save these beautiful creatures.

Top 5 Ways to Save Electricity

It is no secret that electricity prices are not coming down anytime soon. But what can we do about it? In order to save some money, and the environment, South Africans need to be electrically efficient.

Top 5 Ways to Save ElectricityAt Schmidhauser Electrical, we not only strive to deliver the best service, at the best possible price. We also want to help you save money! Here are our Top 5 tips to lower your electricity consumption and save you money:

  1. Switch off equipment when not in use

Yes, this one is obvious but you would be surprised how few people actually do this. Turn appliances off at the wall plug instead of leaving them on standby, as this can still draw roughly 20% or more of standard electricity use. And don’t forget to turn your geyser off when you go on holiday!

  1. Insulate your Geyser

A geyser ‘blanket’ assists your geyser in trapping in the heat, which in turn lowers the electricity that the geyser uses. If your geyser is well insulated you will save money. Click here for a list of approved suppliers

  1. Insulate your ceiling

Ceiling and roof insulation can keep a home 10 degrees cooler in summer and 5 degrees warmer in winter. The more comfortable the indoor temperatures, the less need for electrical heating and cooling. This adds up to savings of approximately 75%

  1. Install efficient Lighting

Switching off lights in unoccupied rooms is an obvious way to save electricity, but checking your light bulbs is just as important. Compact Fluorescent Lamps (CFLs) use 75% less power than old incandescent bulbs, and last much longer. New ‘light-emitting diodes’, or LEDs, are even more efficient than CFLs, and last 130 times longer than CFL bulbs. Currently they have limited applications in homes, but are ideal replacements for halogen down-lighting. LED’s save the most, and although they are expensive, the cost is coming down as the technology develops.

  1. Install an efficient shower head

Your shower flow rate should be no more than 10 litres per minute. To test this at home, hold a bucket under the showerhead for 12 seconds. Measure the amount of water within the bucket with a measuring jug. If there is more than 2 litres then your showerhead is inefficient. A good, modern product will save both water and electricity without compromising your shower experience, and the saving usually pays back the investment within a few weeks.

Bid To Cap Electricity Hikes

With the ever increasing cost of living, the government hopes to contain electricity tariff increases to a maximum of 12% over the next four years.

According to reports, Eskom faces a revenue shortfall of R225bn, with plans to make up the shortfall through a combination of increased tariffs, savings and cash, most likely to come in the form of the conversion of loans to equity by the Treasury. In an effort to return Eskom to financial sustainability, an inter-ministerial task team tasked with finding a solution to Eskom’s financial crisis, has put the above recommendation to the Cabinet in the hope that Eskom will ward off a further credit ratings downgrade to junk status.

Bid To Cap Electricity Hikes According to insiders involved in the process, to secure Eskom’s sustainability, an increase around 16%in tariffs would be ideal, but it is feared a hike of this magnitude may damage the economy, as a result, many in the team believe a 12% increase a year would be best.

While higher tariffs are a necessary part of the package, it does not necessarily mean that Eskom will apply to the National Energy Regulator of SA (NERSA) to have to reopen the multiyear price determination. A likely way forward would be Eskom using its right to claw back unearned revenue through what is called the revenue clearing account, with prices being raised each year anyway, but by a varying margin.

George – a rather big town with a sophisticated infrastructure – is the Hub of the petro industry, as oil tankers that are too big for the natural harbours are moored off the coast of Mossel Bay and the oil is piped from the moorings to the refinery in Mossel Bay, and is usually regarded as the administrative capital of the Southern Cape. It has redressed its former image of a purely industrial town to that of a major tourist mecca – not hard to do when you have two of the top ten golf courses in South Africa, theatres, a wide expanse of forest, rivers and the Indian Ocean on your doorstep.

The Swiss Chamber of Commerce Dinner with Governor of the South African Reserve Bank

It was great to get upfront and personal with the leader of the South African Reserve Bank. Naturally, the Q&A with the Swiss Chamber of Commerce posed some pertinent, yet tough questions that the Governor answered very well. Swiss Investment into South Africa has trebled over the last couple years.

“Since the previous meeting of the Monetary Policy Committee, the inflation outlook has been dominated by the further decline in international oil prices, from around US$75 per barrel in late November to current levels of around US$46 per barrel.

CEO – Jason English from Prommac with the Governor

CEO – Jason English from Prommac with the Governor

Domestic petrol prices declined by almost R2 per litre over the period (and over R3 per litre since August), and a further sizeable decrease is expected in February. This decline in domestic prices occurred despite some offsetting effects from a further depreciation of the rand against the US dollar.

The near-term inflation outlook has therefore changed significantly, but the favourable impact of these developments on both inflation and growth in the longer term will depend on the persistence of the oil price decline.

Even a moderate increase in oil prices going forward will reverse the favourable inflation trajectory, and the inflation and growth benefits, while welcome, are expected to be temporary. At the same time, the impact of load shedding and a deterioration of the global growth outlook are likely to offset some of the positive impacts of the lower petrol price on domestic growth.

The year-on-year inflation rate as measured by the consumer price index (CPI) for all urban areas maintained its recent downward trend and measured 5,8 per cent and 5,3 per cent in November and December respectively, down from its recent peak of 6,6 per cent in May and June 2014. This trend reflected continued moderation in food and petrol prices.

Food price inflation measured 7,4 per cent in December, down from 7,7 per cent in November, while petrol prices declined by 5,5 per cent. By contrast, core inflation, which excludes food, petrol and electricity, remained near the upper end of the inflation target range, but moderated to 5,7 per cent in December from 5,8 per cent previously.

Headline producer price inflation for final manufactured goods was also favourably impacted by declining oil and agricultural crop prices, and measured 6,5 per cent and 5,8 per cent in November and December respectively compared with 6,9 per cent and 6,7 per cent in the preceding two months.

Daniel Schmidhauser with Mrs. Helene Budliger Artieda as the Ambassador of Switzerland to the Republic of South Africa, the Republic of Botswana, the Kingdom of Lesotho, the Republic of Mauritius, the Republic of Namibia, and the Kingdom of Swaziland.

The decline in international oil prices has prompted a downward revision of the oil price assumption in the Bank’s forecasting model, with a significant impact on the near-term inflation forecast. The longer term impact will be dependent on the persistence of these lower prices, which have been a reaction to global supply and demand factors as well as a change in the behaviour of key oil producers.

With supply still plentiful and global growth prospects remaining relatively subdued, lower oil prices are expected to persist for some time. However, our forecast makes provision for a moderate increase over the next two years.

Having averaged 6,1 per cent in 2014, inflation is now expected to average 3,8 per cent in 2015, compared with the previous forecast of 5,3 per cent, and to reach a low of 3,5 per cent in the second quarter of this year compared with 5,1 per cent previously.

The steep decline in 2015, however, produces a strong base effect in 2016, and, when combined with a slightly higher oil price assumption and a depreciated nominal effective exchange rate of the rand, results in an average inflation forecast of 5,4 per cent for the year (5,5 per cent previously), and 5,3 per cent in the final quarter.

The impact on core inflation is far less pronounced. Core inflation is expected to average 5,5 per cent and 5,1 per cent in 2015 and 2016 respectively, from 5,7 per cent and 5,3 per cent previously. The peak is expected at 5,8 per cent in the first quarter of 2015.

Inflation expectations as reflected in the survey conducted by the Bureau for Economic Research at Stellenbosch University moderated from 6,1 per cent in the third quarter of 2014 to 5,8 per cent in the final quarter. Analysts and trade unionists revised their forecasts for 2015 downwards by 0,3 percentage points to 5,4 per cent and 5,9 per cent respectively, while the forecasts of business people were 0,2 percentage points lower at 6,2 per cent.

Forecasts for 2016 are unchanged for the latter category, but both analysts and trade unionists expect a 0,1 percentage point increase in 2016 relative to 2015. While this downward revision is a welcome development, it is too early to assess whether or not this represents the start of a sustained downward trend. At these levels, expectations still remain uncomfortably close to the upper end of the target range.

According to the Reuters poll of economic analysts conducted in January, the median inflation expectation is 5,0 per cent in 2015, rising to 5,5 per cent in 2016. The low point of the inflation trend is expected in the second quarter, with the median at 4,6 per cent, but with expectations ranging from 3,4 per cent to 5,9 per cent.

Inflation expectations as reflected in inflation linked bonds have been volatile, having increased in response to the weaker exchange rate in November, but since mid-December have exhibited a steep decline. Both the 5-year and 10-year break-even rates have declined to levels below 5,5 per cent.

The global economic growth outlook remains mixed, despite a strong performance by the US economy, lower international oil prices and the quantitative easing announced by the ECB. The US economy grew at an annualised rate of 5,0 per cent in the third quarter of 2014, the fastest quarterly growth since 2003.

The unemployment rate continued to decline as job creation accelerated, and lower oil prices have provided a boost to consumption expenditure. Growth in the UK also remains robust, despite slower fourth quarter growth. By contrast, growth prospects in a number of other advanced economies have deteriorated, with Japan in a technical recession and the Eurozone remaining weak amid fears of deflation.

Lower oil and other commodity prices have had divergent implications for growth forecasts of different emerging market economies. Deteriorating prospects in some emerging markets contributed to the lowering of the IMF’s 2015 global growth forecast by 0,3 percentage points to 3,5 per cent, with notable downward revisions to Brazil, China, Mexico, Nigeria, and Russia.

Growth in China is now expected to moderate to 6,8 per cent from 7,4 per cent in 2014 as the economy continues to rebalance towards domestic consumption and reduce vulnerabilities in its banking system. Although Africa remains one of the high-growth regions, weaker commodity prices pose a risk to the outlook.

The impact of lower oil prices on global inflation is expected to influence monetary policy responses. Although the US Fed has indicated that policy rates are still likely to rise from around the middle of the year, recent market expectations are pricing in a later start, as inflation remains low.

Furthermore, Fed guidance suggests that normalisation, when it does begin, is likely to be at a gradual pace. Whereas the UK had been expected to be the first of the advanced economies to begin raising policy rates in the first half of this year, the lower expected inflation trajectory has changed expectations to later in 2015 or early 2016.

While the UK and US contemplate monetary tightening, the ECB has embarked on open-ended quantitative easing, amid risks of deflation, and the slowdown in Japan is also expected to result in a resumption of asset purchases. Since the previous meeting of the MPC, monetary policy rates have been lowered in Canada, China, Denmark, Egypt, India, Norway, Switzerland and Turkey, while policy has been tightened in Brazil, Nigeria, and Russia.

Global foreign exchange market volatility increased in recent weeks in anticipation of quantitative easing by the ECB; possible risks to the euro from the Greek elections; the ending of the Swiss franc floor against the euro; and changing expectations regarding the timing and pace of US policy normalisation.

Since the previous MPC meeting, the euro depreciated by about 10 per cent against the US dollar. Over the same period, the rand depreciated by 5 per cent against the US dollar and by 1,5 per cent against the pound sterling, but appreciated by about 6 per cent against the euro.

Given the relatively high weight of the euro in the trade-weighted index, the nominal effective exchange rate of the rand depreciated by 0,6 per cent.

Market perceptions of a possible delay in US normalisation, coupled with the ECB action, has changed global market risk sentiment and improved the near-term prospects for capital flows to emerging markets.

This follows a generalised sell-off in December. These flows are likely to be highly volatile and expected to be more discriminating than in the past. The spill-over effects of the ECB quantitative easing on the rand are therefore not expected to be as pronounced as was the case with the US quantitative easing.

Capital flows to South Africa have been in line with these global developments. During December, non-resident net sales of bonds and equities amounted to R17,9 billion and R8,2 billion respectively. This trend reversed in late December, as portfolio flows to emerging markets resumed, and in the first three weeks of January, non-residents were net purchasers of bonds to the value of R5,8 billion, while net equity sales amounted to R1,5 billion.

The rand has also been affected by domestic factors, including the disappointing domestic growth and current account deficit outcomes, as well as a resumption of load shedding by Eskom. The rand is expected to remain sensitive to developments on the current account of the balance of payments, which measured 6,0 per cent of GDP in the third quarter of 2014.

Non-oil commodity prices have been on a declining trend since around 2011, so the recent decline in the oil price represents a positive terms of trade shock that could have a favourable impact on the current account. However, this effect is expected to be limited, in part due to the possible constraining effects of load-shedding on exports.

The domestic economic growth outlook remains subdued. Despite an expected growth acceleration in the fourth quarter of 2014 following an annualised growth rate of 1,4 per cent in the previous quarter, growth for 2014 is expected to average 1,4 per cent, with at least one percentage point lost to work stoppages.

The Bank’s forecast for growth in 2015 has been revised down from 2,5 per cent to 2,2 per cent, and that for 2016 from 2,9 per cent to 2,4 per cent. This forecast attempts to take account of electricity supply disruptions which more than offset the positive growth impact of lower oil prices.

The Bank’s composite business cycle indicator has followed a moderate downward trend in the past months, confirming the subdued outlook. More positively, the RMB/BER business confidence index returned to net positive levels for the first time since the first quarter of 2013, when it increased by 5 points to 51 index points in the fourth quarter of 2014.

The mining sector, which expanded output by 6,2 per cent on a three-month-to-three-month basis in November, is expected to contribute positively to fourth quarter growth, despite the 1,2 per cent month-to-month contraction in that month. Nevertheless, platinum output still remains below pre-strike levels, and the sector is likely to face headwinds in 2015 from lower commodity prices and electricity supply uncertainty.

The outlook for the manufacturing sector, which contracted for three consecutive quarters, is looking more positive following the resolution of the strikes in the sector, with a three-month-to-three-month increase in November of 4,1 per cent.

However, output declined by 2,1 per cent on an month-to-month basis due to electricity supply disruptions. The Kagiso PMI declined to 50,2 index points in December from 53,3 points in November, indicating an expectation of positive, but subdued growth in the sector.

Although gross fixed capital formation was the largest contributor to GDP growth in the third quarter of 2014, the trend remains weak. Growth in gross fixed capital formation measured 2,1 per cent in the third quarter of 2014 following two consecutive quarters of contraction. While the private sector investment reversed its negative trend in the previous two quarters, at 0,7 per cent it remains extremely low.

The weak growth and investment trends are reflected in the slow rate of formal sector employment creation. According to the Quarterly Employment Survey of Statistics South Africa, employment levels decreased by 5,9 per cent on a seasonally adjusted basis in the third quarter of 2014, mainly due to the termination of temporary employment contracts related to the general elections in the second quarter.

This contributed to the annualised 20,8 per cent decline in public sector employment, while private sector employment over the quarter increased by 0,1 per cent or 2,000 jobs. Compared with a year ago, employment increased by 1,0 per cent, predominantly in the public sector.

Growth in real final consumption expenditure by households remains weak, despite a slight acceleration in the third quarter of 2014 to 1,3 per cent from 1,1 per cent in the previous quarter. However, expenditure on durable goods increased at an annualised rate of 6,2 per cent, and reflected in stronger new vehicle sales.

Retail trade sales improved in November with a month-to-month increase of 1,5 per cent, and year-on-year by 2,6 per cent. Consumption expenditure is expected to get some boost from lower petrol prices. Consumer confidence, while still relatively low, also showed a slight improvement in the fourth quarter of 2014, having increased to a level of zero from the previous level of -1.

Trends in bank credit extension to the private sector continue to reflect tight conditions for households while credit to the corporate sector remains buoyant. Growth over twelve months in total loans and advances to the private sector measured 8,7 per cent in November.

However, growth in loans to households, which has been steadily declining over the year, reached a low of 3,6 per cent in November, while that to the corporate sector recorded 15,2 per cent. Growth in general loans to the private sector, mainly unsecured lending, remains weak, despite an increase to 2,9 per cent in November; growth in instalment sale credit and leasing finance moderated further to 6,1 per cent; while mortgage advances continued to grow below 3 per cent in line with the subdued housing market.

These trends are assessed to be a reflection of both continued tight credit conditions and weak demand, as household indebtedness remains high.

Wage settlements indicate a continuation of above-inflation wage and salary increases. According to Stats SA data, nominal remuneration per worker in the formal non-agricultural sector increased at a year-on-year rate of 6,9 per cent in the third quarter of 2014. With labour productivity growth of 0,3 per cent, growth in nominal unit labour costs amounted to 6,7 per cent in the quarter.

According to Andrew Levy Employment Publications the average settlement rate in collective bargaining agreements amounted to 8,1 per cent in 2014, compared with 7,9 per cent in 2013. The outcome of the public sector wage settlement, due to be implemented in April, is expected to have an important bearing on the general trend of wage settlements in the economy in 2015.

Food prices remain a major source of inflation pressure with increases still in excess of the headline inflation rates. However, the moderation observed in recent months is expected to continue, despite the reversal of the downward trend in manufactured food prices at the producer level since October.

Agricultural food price inflation remains low, having measured 1,4 per cent in December, with a bumper maize crop expected this year. Global food prices have continued to decline, with the Food and Agricultural Organisation food price index declining by 3,7 per cent in 2014.

The inflation landscape has changed significantly in recent weeks, but the outlook for international oil prices is highly uncertain. Unless a persistent oil price decline is assumed, the impact on the inflation trajectory will dissipate over time.

The key issue for the MPC is the extent to which second round effects become evident and lead to a more generalised inflation moderation over the forecast period, and to a further and sustained decline in inflation expectations. The forecast of core inflation at this stage indicates a relatively muted decline in underlying inflation.

The rand exchange rate against the US dollar remains an upside risk to the inflation outlook and is vulnerable to the timing and pace of US policy normalisation, despite the partial offset from a weaker euro.

Further depreciation of the rand against the US dollar could also erode the positive benefits of lower oil prices on inflation. The slow pace of contraction of the current account will continue to keep the rand sensitive to both domestic and external factors.

Along with the exchange rate, wage and salary increases in excess of inflation and productivity growth remain an upside risk to the inflation outlook. Unless nominal wage increases moderate in the lower inflation environment, the beneficial effects of the depreciated currency on competitiveness will be eroded.

The MPC views the overall risks to the inflation outlook to be more or less balanced, with no evidence of excess demand pressures on inflation.

Notwithstanding a downward revision to the growth forecast, the risks are assessed to be moderately on the downside. This is due to the likely protracted nature of the electricity supply constraints, and their consequences for domestic output as well as for business and consumer confidence.

However, given the supply side nature of this constraint, the impact of further monetary policy accommodation on growth is likely to be limited, in the absence of progress being made in the alleviation of electricity constraints. In addition, the implementation of structural reforms is necessary to raise potential growth.

For some time we have emphasised that we are in a process of interest rate normalisation. The lower inflation path gives us some room to pause in this process, particularly against the backdrop of continued weakness in the economy. The MPC has therefore unanimously decided to keep the repurchase rate unchanged at 5,75 per cent per annum.

The MPC is aware that the moderation in inflation could raise expectations of lower interest rates. The MPC is of the view that the bar for further accommodation remains high and would require a sustained decline in the inflation rate and inflation expectations.

Lumens

What is it?: Lumen is a unit of light measurement otherwise known as luminous flux.

We use lumens to compare the total amount of light output from a light emitter. However, lumens isn’t the be-all and end-all. In fact, lumens will only tell you one part of the picture because when it comes to producing a great beam pattern, it doesn’t give you enough information to tell you how the light output is used. A comparable analogy of lumens is an automobile’s total brake horsepower (BHP).

To measure lumens, we use a highly specialized light integrating sphere.

lux-and-lumens-1
Lux

What is it?: Lux is a unit of light measurement taking area into account. In other words, light intensity.

We use lux to measure the amount of light output in a given area, where one lux is equal to one lumen per square meter. Lux is a great measurement for determining what we see as the brightness of a beam. If the light output is concentrated over a smaller area, we see this as very bright. If the light output is spread over a larger area, we see this as very weak. We normally use mirrors, reflectors, and optics to control the path of light and create the desired beam pattern. Lux also determines the magnitude of light intensity travelling over distances. A light that is configured for high lux output will travel farther but will have a smaller footprint of light (e.g. lighthouse spotlight), and a low lux level will be configured to travel shorter distances but have a larger footprint (e.g. decorative down lighting or ambient lighting).

To measure lux at a specific location, we use a device called a lux meter.

light-output

Beam Angle (FWHM)

What is it?: Beam angle is the angle of which a light is emitted. More specifically, it is the Full Width at Half Maximum.

Since there is no real way to measure the ‘edge’ of light we measure the beam angle from where the light is at 50% intensity (FWHM). By being able to measure where 50% light intensity ends, it gives us the majority of where the light is used thus representing the beam angle. Smaller beam angles will have an intense hot spot, where as larger beam angles will have a lesser intensity (due to a larger area). Take a look at our beam shots and see if you can gauge where 50% intensity ends, giving you the beam angle.

Watts

What is it?: Watt is a unit of power consumed.

The more power a light emitter consumes, the more lumens it should produce. However, the relationship is non-linear and we can use the numbers from wattage and lumens to measure the efficiency of a light emitter. LEDs have far outpaced the industry as the most efficient light emitter and can produce more light than older halogen lights. One thing to note is the more power is consumed, the more heat is produced, which is wasted energy.

Nuclear energy in South Africa

The advantages and disadvantages of nuclear energy have made this energy source one of the most controversial on the market today. Advocates for and against nuclear energy are equally passionate about their causes. Understanding the pros and cons of this energy source can help you make a more informed decision about your own energy use.

Advantages of Nuclear Energy

Despite potential drawbacks and the controversy that surrounds it, nuclear energy does have a few advantages over some other methods of energy production.

Expense
Less uranium is needed to produce the same amount of energy as coal or oil, which lowers the cost of producing the same amount of energy. Uranium is also less expensive to procure and transport, which further lowers the cost.

Reliability
When a nuclear power plant is functioning properly, it can run uninterrupted for up to 540 days. This results in fewer brownouts or other power interruptions. The running of the plant is also not contingent of weather or foreign suppliers, which makes it more stable than other forms of energy.

No Greenhouse Gases
While nuclear energy does have some emissions, the plant itself does not give off greenhouse gasses. Studies have shown that what life-cycle emissions that the plants do give off are on par with renewable energy sources such as wind power. This lack of greenhouse gases can be very attractive to some consumers.

Disadvantages of Nuclear Energy
One of the reasons that nuclear energy falls under fire so frequently is due to the many disadvantages it brings.

Raw Material
Uranium is used in the process of fission because it’s a naturally unstable element. This means that special precautions must be taken during the mining, transporting and storing of the uranium, as well as the storing of any waste product to prevent it from giving off harmful levels of radiation.

Water Pollutant
Nuclear fission chambers are cooled by water. This water is then turned into steam, which is used to power the turbines. When the water cools enough to change back into liquid form, it is pumped outside into nearby wetlands. While measures are taken to ensure that no radiation is being pumped into the environment, other heavy metals and pollutants can make their way out of the chamber. The immense heat given off by this water can also be damaging to eco systems located nearby the reactor.

Waste
When the uranium has finished splitting, the resulting radioactive byproducts need to be removed. While recycling efforts of this waste product have been undertaken in recent years, the storage of the by-product could lead to contamination through leaks or containment failures.

Leaks
Nuclear reactors are built with several safety systems designed to contain the radiation given off in the fission process. When these safety systems are properly installed and maintained, they function adequately. When they are not maintained, have structural flaws or were improperly installed, a nuclear reactor could release harmful amounts of radiation into the environment during the process of regular use. If a containment field were to rupture suddenly, the resulting leak of radiation could be catastrophic.

Shutdown Reactors

There have been several nuclear reactors that have failed and been shutdown that are still in existence. These abandoned reactors are taking up valuable land space, could be contaminating the areas surrounding them, yet are often too unstable to be removed

Electricity Fun Facts

$

0

1. Electricity was never invented. It was discovered. The difference between invention and discovery is that humans can invent something which does not already exist in nature and discover something which already exists in nature.

2. While many people give credits to Benjamin Franklin for the discovery of electricity, it is far from being true. Franklin conducted a series of experiments that merely helped establishing a relationship between electricity and lightning.

3. So, who discovered electricity? To answer this question, we need to travel back in time. How far back? More than a couple of thousand years back! Yes, we are looking back into the ancient times.

4. Static electricity was discovered by the ancient Greeks some 600 years before the beginning of the Common Era. They noticed that when amber and fur are rubbed together, they attract each other. Eureka! They discovered static electricity.

5. Romans weren’t that dumb either! After all, they built the mighty Roman Empire. Somewhere in the 1930s, archaeological excavations of the ancient Roman sites revealed some pots wrapped with copper sheets from inside. Careful studies of the discovered pots led the scientists to believe that these were ancient batteries.

6. And how can we forget the Persians? The dig sites near Bagdad revealed similar pots and scientists, after careful examination of those pots and their internal components, could not come up with any alternative theory but to suggest that the only purpose of those pots was to generate weak electric current.

7. So the question is, what did the ancients do with these batteries? Scientists believe that they used them for electroplating artefacts that are now stored in museums all around the world.

8. Ancient Egyptian tombs are, as believed by many scholars of likes of Sir J. Norman Lockyer, are blatant proof that ancient Egyptians used electric lamps. The arguments put forward are that in the deepest recesses of the freshly-opened tombs, there are no evidences of soot marks on ceilings. He argues that using oil lamps or dim candles to aid the artisans in embellishing the walls with accurate colours and fine details of the deceased would leave soot marks on the ceilings.

9. He further argues that using mirrors to reflect the sunlight is also not a close possibility because it would require very complex arrangement of the mirrors in the maze of rooms found in those tombs. Furthermore, just in case an artisan stepped right in front of a reflecting mirror, the whole critical link would break.

10. Lockyer points out that all the freshly-opened tombs (those that were not intruded by grave thieves and looters) did not show any smoke residue anywhere on walls or ceilings, which goes on to prove that ancient Egyptians probably used electric lamps.

The issue of Certificates of Compliance (COC) is regulated by the Occupational Health & Safety Act, 1993 read with the Electrical Installations Regulations 2009. It is no longer regulated by the Machinery and Occupational Safety Act No. 6 of 1983 and the Electrical Installations Regulations of 1992 as still stated in most offer to purchases. The new regulations make it clear that no user may sell property without a valid COC.

User: is defined to include an owner, mandatory and lessor. A mandatory is any person involved in the sale of property. This included an estate agent.

Sell: is defined and include – a for sale notice board, a lease and a donation.

Section 22: Subject to Sec. 10(4) where a safety standard is prescribed, no person shall sell or market an article, plant, machinery etc. unless it complies with the safety standard.

Section 10(4): Confirms we may transfer the responsibility to another party to obtain the COC, PROVIDED that it is in writing. Legally no person is allowed to advertise their property as for sale without a valid COC. The estate agent needs to ensure that an owner has this COC when the property is put on the market. No person is also allowed to donate a property (example: family transfers or 1/2 share transfers) without a valid COC.

REGULATIONS AND STANDARDS:
Regulations in terms of Electrical Installation Regulations 2009. Standards in terms of SANS 10142-1 there is two sections in terms of standards:
1. Mandatory requirements – what needs to be done?
2. Recommendations – what can be done? This is not legally enforceable but it impacts new installations.

WHO MAY ISSUE COC?
Only a registered person may issue a COC. Therefore the person must have a licence issued by the Department of Labour. An unregistered person may work at the property, but only under supervision of a registered person. The registered person needs to personally ensure the standard of the work done by the unregistered person before he signs the COC.

USE (OWNER) RESPONSIBILITIES:
1. For every addition or alteration to the installation a user should obtain an additional COC. Example: if a plug is moved or installed – new COC covering this.
2. No transfer of COC is permitted if the COC is older than 2 years.
3. Cannot transfer a COC if any alterations or additions were done at the property, except if there is an additional COC to confirm this to be compliant.

DISPUTES AND THE GEIA:

1. When a dispute arises regarding the validity of a COC the GEIA must be called to inspect.
2. Person requesting the inspection will have to pay.
3. Should the certificate be declared not valid – the GEIA will request that a new certificate is issued.
4. Should the defect be negligence on the part of the registered person, the inspector shall report the electrician to the Chief Inspector.

REQUIREMENTS TO BE ELECTRICAL CONTRACTOR:
Must be registered with the Chief Inspector (Department of Labour) or person appointed by Chief Inspector. – Must have:
1. Fixed address and telephone number (must reflect on COC – no PO Box numbers allowed)
2. He must employ a registered person full time or be a registered person himself.

INVALIDATION OF COC:
Any change / correction to the COC renders it invalid – must obtain a new COC. A lost COC cannot be replaced – a new COC needs to be issued. Invalid if the test report is headed “Certificate of Compliance”

WHAT DOES A VALID COC LOOK LIKE?
COC must have:
1. The department of Labour Logo
2. Headed “Annexure 1″ and must follow the format described in the Regulations.
3. Must head “Department of Labour”.
4. Must have a unique number given by the contractor.
5. Must be attached to the test report.

Thermal imaging cameras are advanced pieces of technology that can detect heat radiated by any object or living creature. First developed by a Hungarian physicist in the 1920s, thermography has come a very long way.

The technology utilizes lenses that focus on the waves produced from the infrared energy that can be detected in all objects onto an infrared sensor arrangement. The energy is transformed into electrical signals creating a video image. Relative to the object and its surroundings, the infrared camera generates a thermal profile. The warmest areas appear white, creating a distinctive appearance, making it easy to identify various objects.

Uses of thermal imaging:
1. Uncovering the Identity of the Boston bomber
Thermal technology aided the police in their hunt for the 19-year-old Dzhokhar Tsarnaev, Boston marathon bomber, in 2013. After determining traces of blood and what seemed to be body in a boat, authorities used a helicopter fitted with a thermal imaging device which proved it was in fact the suspect’s body. The technology succeeded in detecting the heat radiating from the 19-year-old, despite being under the cover of the boat.

2. Slough Borough Council

Slough Borough council has assessed that up to 3000 people are living illegally in the town and as a result of these figures, have recently sent up an aircraft with thermal-imaging cameras to detect any heat being emitted from out of unlicensed buildings. Over 200 alleged illegal dwellings were found during a two hour flight and the process is anticipated to be rather frequent to find even more suspects.

3. Japanese Earthquake and Tsunami
Thermal imaging cameras were used to save survivors from the recent Japanese earthquake and tsunami. Video cameras were positioned on the end of flexible poles and squeezed through openings in the rubble to help detect survivors as their body heat warmed the rubble in close proximity them. The technology saved precious time, as searches could be conducted proficiently during complete darkness, sunlight and severe weather conditions. It also meant that less time was consumed shifting unnecessary rubble, permitting victims to be rescued in the shortest time possible.

4. Ford Engineers
Ford engineers are currently use thermal imaging technology to recognize where air is escaping from a vehicle. The technology allows Ford to test a variety of different ways of how they can contain air within the vehicle, by varying the design and use of insulating materials. This is very advantageous to such engineers as preventing air leaks reduces noise as well as develops heating and cooling efficiency, which consequently reduces energy loss

The Western Cape Disaster Management Centre said on Thursday that electricity had been restored to 90% of areas across the Metropole that experienced outages due to the storm that battered the city this week.

Believed to be the worst storm in three decades, it made landfall late on Tuesday night, resulting in eight fatalities, countless uprooted trees and damage to properties. Thousands of people were also displaced due to flooding.

Disaster Risk Management’s Charlotte Powell said roofs were blown off homes in Mitchells Plain, Lavender Hill, Ottery, Delft, Phillipi and Nyanga.
“The City’s Recreation and Parks Department has removed and are continuing to remove uprooted trees in Kewtown, Rondebosch, Bergvliet, Belgravia and various other areas in the Metropole to ensure roadways are cleared.”

She said 827 structures and 2 502 people were affected by flooding in Imizamo Yethu in Hout Bay, while in Macassar Village, 400 people were affected.
“The Informal Settlements Department will make assessments and provide flood kits.”

Powell said electricity department officials would work throughout the day to restore electricity to those areas still affected by blackouts.

Disaster Management officials would also continue to do damage assessments of all affected areas.
