GIVE-AWAYS TO GET THAT HOLIDAY ADRENALIN PUMPING
PERSONALITY OF THE MONTH: IAN GREYLING
WHAT WOULD LIFE BE IF WE HAD NO COURAGE TO ATTEMPT ANYTHING?
IG: I started working in 1973 and completed an Electrical Apprenticeship at Welkom Gold Mine. I moved to Safmarine in the Merchant Navy where I learnt tenacity and to think ‘on my feet’ I was on the ships for about two years, and at the time, I completed a diploma in Industrial Electronics. Sparks: What are the greatest changes you have seen over the years? IG: The change in technology is overwhelming. Industrial electronics have taken the world by storm with LED technology, solar power, fly- by-wire and many more. Sparks: What major projects have you worked on and what is your greatest accomplishment? IG: I have been involved in various projects over the years but I think my greatest accomplishment is to still be running a successful business after 35 years. Sparks: Have you won any awards? IG: No, nothing I can brag about. Sparks: Who has been your inspiration or have you had a mentor who has influenced your career? IG: There have been many people who have inspired me whether meeting them or reading about them. Emulating them has been a form of them mentoring me. Having a balanced life, different interests and giving back to various charities is also inspirational. Sparks: What, to your mind, is one of the biggest challenges facing the industry at this time? IG: I have noticed a great lack of people with technical skills, and people who take pride in their work. It is very difficult to source good technical people and we really need them to sustain infrastructure and to minimise costs. Sparks: What do you enjoy most about your job? IG: I have a very diverse job and I thrive on it. I also enjoy dealing with people and solving problems for our customers. Sparks: How do you motivate your staff? IG: I am certainly aware that staff get demotivated and pessimistic at times. Training our staff, keeping them informed of products and management procedures as well as engaging them are some of the things that make them feel appreciated and they in turn develop a sense of belonging. As a result, they do not feel they are just a number, but rather links in the chain that forms the success of the business. Sparks: If you could ‘do it all again’, would you change anything? If so, what would that be? IG: I would definitely not start an electrical business - there are much easier businesses to run! I’m only joking! I would not change much, it has been a winning recipe, except that if I had the opportunity to start all over again, I would spend more time on staff training, modelling, database within a 20 km radius from where the service request is logged, utilising the mobile phone’s location service to ensure an ap- plicable and speedy response. The app offers a range of benefits to those registered on the BrightArk service provider network, amongst others, leads, free pub- licity, no limits on projects, a choice of working hours, favourable ma- terial prices, easy-to-use technology, a paperless operation and guar- anteed payment when the work had been done to satisfaction. The BrightArk app for property owners will soon be launched. Right now, independent service providers can register for inclusion on the app’s database by following this link: bit.ly/BA-signup. Registration is free.
study opportunities and giving staff more responsibilities so that they can become more influential in the business. Sparks: Would you advise a person leaving school to enter the electrical industry? And why? IG: Definitely! We really need technical hands-on people in our country, and as technology grows, we need to keep up and grow with it. The electrical field gives a great background to ‘spread your wings’ into so many different areas. Sparks: What is your advice to electrical contractors and/or electrical engineers? IG: Never give up, good things come to those who don’t! Sparks: What is your favourite quote? IG: I have two. The first by Vincent van Gogh – “What would life be if we had no courage to attempt anything?” And the second by Alice Cooper, “Mistakes are part of the game. It’s how well you recover from them, that’s the mark of a great player”. Sparks: Name three things on your ‘bucket list’ (things you want to do before you ‘kick the bucket’). IG: I would like to be able to fly a helicopter; sit (not climb) on top of Mount Everest; and see as many interesting places on this wonderful planet as I can – Northern Lights, fishing in Alaska, experience Africa – the list just goes on!
IAN GREYLING is CEO of Electrahertz; he is passionate about skills, training and development in the industry. While he has been involved in various projects over the years, his greatest accomplishment has been running a successful business for over 35 years.

NEW BUSINESS OPPORTUNITIES IN PROPERTY MAINTENANCE
GREEN ENERGY SOLVES VETERINARY CLINIC’S ELECTRICITY ISSUES T he Panorama Veterinary Clinic & Specialist Centre has reduced its electricity grid usage by 17% through the use of alternative energy genera- tion recently installed by Energy Partners Home Solutions. Cala van der Westhuizen, Head of Marketing and Sales at Energy Partners Home Solutions, a division of Energy Partners and part of the PSG group of companies, explains that the clinic, which offers a 24-hour emergency service, had been paying at least R20 000 per month in electricity costs. In addition, its consumption often exceeded its breaker limit, which caused power outages and sporadic tripping of the power supply. The clinic made contact with Energy Partners at the beginning of 2017 with the objectives of reducing its electricity bill, lowering its impact on the environment, increasing supply capacity and adding to the value of the business. Energy Partners Home Solutions conducted an in-depth analysis into the specific requirements of the facility and determined that a 25 kW three- phase SMA inverter and 17.2 kWp polycrystalline solar panels would provide best results. “After we installed the new system, the facility’s municipal electricity bill reduced by an average of R3 565 per month and CO 2 emissions were cut by about 25 tonnes per year. More importantly, the team was able to increase the electricity supply capacity of the clinic by up to 25% during peak solar production, which means that future power outages due to overloading could be eliminated,” van der Westhuizen explains. He concludes that renewable energy has become more reliable and affordable than ever before and homeowners and small businesses alike are encouraged to research and consider the possibilities of installing alternative generation on their properties to reap the benefits.

BANKING ON SUNSHINE: SOLAR SWITCH FLIPPED AT WESBANK AND FNB FAIRLAND CAMPUS
T he switch has been flipped on a world-class solar panel installation at the WesBank and FNB campus in Fairland, north of Johan- nesburg. Just 12 months after construction began on the large-scale renewable energy project, the 150 000 m 2 Fairland campus now supplements its electrical requirements using sunshine – help- ing the bank reduce its carbon footprint by more than 2 700 tonnes per year, while lowering its de- pendency on the local power grid and passing the benefit to the community of Fairland. With more than 5 000 WesBank and FNB em-
and FNB’s initiatives to earn a 5-Star rating for its Fairland campus from the Green Building Council of South Africa (GBCSA).
is capable of generating 1.99 MW – or enough to provide power to nearly 1 300 households. “Flipping the switch on a newera for our landmark building is very exciting. We have passionate people working to reduce our carbon footprint wherever possible, using innovative solutions along the way,” says Chris de Kock, CEO, WesBank. “Coincidentally, our move to renewable, sustainable energy comes at a time when the motor industry is facing similar challenges. I’m thrilled that WesBank can also say it is embracing the future of energy.” This solar panel installation is one of WesBank
ployees based at the Fairland Campus, shaded parking is at a premium. In 2015, a feasibility study was commissioned to establish the possibility of re- placing ageing carports with solar panels. What started out as a parking lot with 978 di- lapidated shade-cloth parking bays has been trans- formed into a futuristic field, with 7 647 reflective photovoltaic cells – across 1 010 parking bays – harvesting solar energy that helps power the cam- pus. Power from the solar panels is routed through 83 km of dc cabling, where power is stored across 83 dc-to-ac inverters. At peak efficiency, the system
ILLEGAL GEYSERS AT RISK OF EXPLODING BECAUSE OF WATER OUTAGES N o solar geysers that comply with SANS could burst or explode as a result of pro- longed water outages. This is according to Arno van Wyk, managing director of solar hot water heating systems supplier, MrSola, disputing recent assertions that Phase One of the City of Cape Town’s critical water shortage plan could lead to solar water geysers bursting or exploding in af- fected suburbs. “Solar geysers and panels that are up to standard simply won’t suffer any major dam- age during awater outage. Electrical geysers are also only at risk of burning out their elements if they are completely empty. In neither of these cases could one reasonably expect an explosion.” One of the most important points to note, according to Van Wyk, is that all geysers, both electrical and solar powered, need to be fitted with temperature pressure release valves. “These valves open to release water if the temperature inside the geyser exceeds 90°C, or the pressure goes 50% over the certified working pressure of the geyser. Geysers are pressure tested at 200% of certified working pressure. The valve only closes again after the water temperature falls below 70°C. So if no cold water flows into the geyser; the valve remains open and the geyser still cannot burst.” He adds that the solar panel itself also has a steam release valve which ensures that pressure does not build up if no water circulates. “To prevent scalding if the water in the system gets too hot, a mixing valve is installed. This ensures a maximum hot water temperature of 55°C flowing to the point of use, i.e. shower heads and taps.” “Some cheaper solar heating systems that operate with vacuum tubes could potentially suffer damage if they do not have water but luckily there aren’t toomany of those in themarket. Most modern solar heating systems make use of evacuated tube technology, which does not have the same risks,” he adds. According to Van Wyk, all homeowners need to ensure their geysers are compliant with SANS codes. “If they are unsure, they need to have a professional inspect their system. In the City of Cape Town, it is a legal requirement that a home’s geyser is compliant and it is a prerequisite if one wants to sell a house.” Finally, Van Wyk states that there are some precautions homeowners need to take into account if their water supply is cut off. “Whether a solar or an electrical geyser, it is better for long- term maintenance and care if they are not empty. Therefore, we would advise that if there is a water outage in your area, use only cold water as far as possible. If you do need to use the hot water, switch off the geyser. This goes for a solar geyser, which has an electrical component, as well.

WORKING KNOWLEDGE BY TERRY MACKENZIE HOY
TRANSFORMERS ... NOT AS SIMPLE AS THEY SEEM
run two transformers of different vector groups in parallel. A typical vector group is Dyn11. You shouldn’t run transformers in parallel anyway. Most transformers have an ‘off load’ tap changer, which means you can increase or decrease the secondary voltage by altering the high voltage tap. ‘Off load’ means do this with the transformer switch off., i.e no load current flowing at all. Otherwise, you will blow yourself up. Don’t try! The tapping is a bit confusing. Setting the tap to 105% will decrease the secondary voltage by 5%, not increase it. Check the name plate. You will also see on the name plate a figure, ‘% impedance’. This is the secondary volt drop, no load to full load. So, if a transformer produces 420 V at no load, with a 6% impedance it will produce 420/1.06 V = 396 at full load. There it is. Quite simple, but not as simple as it seems...
ings are in a tank filled with transformer oil (you get ‘dry’ transformers, which have epoxy resin insulation). The tank can be kept topped up by an oil filled tank, called a conservator. If so, there is a special relay which detects if the tank is dry or if there is a short circuit in the transformer. This relay is a ‘Bucholz’ relay and is wired to give an alarm if the oil level is low and trip if there is a short circuit. Alternatively, the transformer can be sealed with no conservator or Bucholz. This is common in sizes of 630 kVA and below. Generally,awinding temperature alarmand trip relay are incorporated to detect over-temperature. Almost without exception, the primary winding (the high voltage winding) is connected in delta and the secondary winding in star. The resulting phase angle difference gives the transformer ‘vector group’. Don’t worry if you don’t get this; all you have to know is that you can’t
THIS MONTH, I thought I would share some knowledge about trans- formers as may be found in electrical installations (as against audio and electronic). There are three broad categories of transformers: pow- er distribution transformers, voltage transformers and current trans- formers. We’ll leave out large power system transformers since they fall under Eskom and municipalities. Power transformers are made to SANS specification SANS 60076- 1:2011 Power transformers – Part 1: General. The standard sizes are 200 kVA, 315 kVA, 500 kVA, 630 kVA, 800 kVA, 1 000 kVA, 1 250 kVA, 1 600 kVA, 2 000 kVA and 3 150 kVA. Naturally bigger sizes exist. Most distribution transformers have a primary voltage rating of 6 600 V, 11 000 V, 22 000 V or 33 000 V, three-phase. In Cape Town, the most common rating is 11 500 V but not in the rest of
MARIO MAIO WINS STANDARD BANK SAPCC ENTREPRENEUR AWARD 2017 O wner and managing director of ACDC Dynamics, Mario Maio, has won the 2017 Standard Bank, SAPCC (South African Portuguese Chamber of Commerce) outstanding professional/entrepreneur award. As a proud member of the South African Portuguese community, the award means a great deal to Mario, who always does his best to grow his own business and to advance the cause of the South African Portuguese community in any way he can. The award is a deserved reflection of his hard work and of just howmuch he has managed to achieve. the country. For years, the secondary voltage was 400 V three-phase, but more recently it’s 420 V, which gives an unloaded single-phase voltage of 242 V. This is because municipalities and Eskom guarantee a terminal point voltage at the consumer of 220/240 V so the 420 V rating allows more volt drop in supply cables. There is a diversity of variations in power distribution construction. Bushings: The bushings can be open or enclosed in a terminal box. If open, it is fairly simple to discon- nect and replace the transformer but open bush- ings are a hazard and may be affected by debris and weather. Let me hasten to add that this occurs very occasionally and if you fence in the trans- former, it is more or less safe from human contact. Enclosed bushings require specialised terminations, which make disconnection and replacement diffi- cult, but the transformer need not be fenced in and can be in the same substation as the switchgear. Skids or wheels: Transformers can be mounted on skids or wheels, depending on how portable you want them to be. Skids are most common. Bolted or welded casing: The top plate of the trans- former can be bolted with an intermediate gasket, or welded. The bolted version allows for removal of the transformer core, which is hardly ever required. With or without conservator: Power transformers are generally oil-insulated, where the transformer wind-
INNOVATIVE FIT-OUT BOOSTS ‘GREEN’ STATUS OF GE AFRICA INNOVATION CENTRE
L eading architecture, interior design, and space-planning practice Paragon was tasked by GE Global Properties to design and fit-out the Centre (GEAIC), the first green- and LEED-cer- tified GE building in Sub-Saharan Africa. GE opened its first African-based innovation centre in Johannesburg in June 2016 as part of its investment in developing home-grown solutions for Africa. The R80 million facility is the twelfth GE Innovation Centre globally. It is home to GE’s inno- vation focus across Africa, within its key business sectors of healthcare, aviation, energy, oil and gas, power, and transportation. “A holistic view was adopted for the building. We have arrived at a stage of sustainable design inter- nationally, with the minimum level being quite high. Being more than the sum of its parts, the overall fit-out aims to achieve substantially over and above
this minimum level,” says Paragon Interface Direc- tor, Claire D’Adorante. The building is designed to operate more ef- ficiently than the market average, featuring Xeris- caped gardens and water-efficient planted walls, occupancy-controlled lighting, substantial external views for occupants, acoustically-tested and -de- signed environments, and efficient water usage. D’Adorante explains that in order to be an In- novation Centre it had to prescribe to global and local best practice towards a more sustainable built environment. The overall thought process of the design focused on the use of environ- mentally-sound materials, acoustics, flexibility, ergonomics, visual comfort, waste management and water/electricity reduction in the appliance/ technology used.

UNIDRIVE ELECTRIC MOTORS RECLAIMS ITS POSITION
FIRE & SECURITY TECHNIQUES LAUNCHES NEW FIRE ORBS IN SOUTH AFRICA
I t is not every day that a company faces liquidation and the prospect of devastating job losses, and sur- vives to tell the tale. Unidrive Electric Motors Company is embarking on a second lease on life under new, majority-black women-owned management, following the acquisi- tion of the majority stake in the business by Ayanda at Work (Pty) Ltd. Between 2012 and 2013, Unidrive had cash flow challenges which pushed the business into a precari- ous financial position and the possibility of closure. This position led the company to cede its market posi- tion in the local armature winding space and lose busi- ness opportunities as clients lost confidence. Unidrive managing director Theo Mashego says, “Unidrive is one of the most recognised players in the refurbishment and supply of electric motors, and its demise would have been very sad. “We entered into discussion to acquire the majority stake in this business at just the right time, before a decision was taken to pull the plug. Starting a business such as Unidrive afresh - off the ground – could take between five and 10 years and the experience of the workforce would take forever to build again,” he says. Mashego has spent the past two years refocusing Unidrive’s business model and rebuilding business confidence. The company has re-examined its product and service offering to ensure it is compatible with the markets being serviced. “We are very competitive in the market for the re-
pair of up to 450 kW, up to 1000 V motors, and we comply with SANS 60079-0 and 60079-1 for repairs of flameproof motors. We comply with SANS 60079- 0/15/19 for spark-roof motors and pride ourselves on an impeccable safety record over the past two years. It is very important we achieve these standards as they give our clients confidence that their products are in good hands,” he says. The company saw its turnover growing in double digits between 2015 and 2016, with more upside ex- pected in 2017 with the recovering economy. “There are lots of positives in this rejuvenated business to give us indications of a positive future,” says Mashego.
A SIMPLE-TO-USE FIRE-EXTINGUISHING device has been introduced to the local mar- ket by Centurion’s Fire & Security Techniques (FST). The FST Fire Orb is a self-activating, portable fire-extinguishing device that activates automatically when in contact with open flames. It is effective for use against all types and classes of fires, from electrical shortages to fat, oil, and paraffin stove fires, vehicle fires, and workshop and factory fires. The FST Fire Orbs can be wall-mounted for maximum effectiveness, explains Fire & Security Tech- niques CEO, Neil Hughes. Each FST Fire Orb weighs only 1.3 kg, making it lightweight and easy to handle and operate. It consists of a lightweight case of frangible material, with a protective exterior sheathing. The internal cavity contains a pyrotechnic detonator at or near the centre of mass. It is activated by fuse cords extending to the surface. The device is filled with mono am- monium phosphate, a non-conductive dry chemical powder, which means it can be used on any electrical product without resultant damage. The detonator incorporated in the FST Fire Orb is a small, non-lethal explosive mechanism. The force of the bursting device is non-harmful to humans, animals, or property, and the effect is further minimised by the use of low-density, low-mass components. This means no part of the device has sufficient mass or density to constitute a ballistic hazard or result in concussive shock. The FST Fire Orb activates automatically upon direct contact with open flames, and not heat. Upon activation, it emits a loud bang of between 119 dB to 138 dB as a warning signal, and disperses the dry chemical powder in order to extinguish the fire. The device is simply rolled or thrown into the fire, whereupon it activates within three to seven seconds. FST Fire Orbs have passed tests conducted by the PSB Corporation and Sirim Qas International for Class A, B, and C fires. Additional tests carried out include thermal resist- ance, burst effect, sound level, compression resistance, and drop tests. The devices are regulated and certified in accordance with ISO 9001: 2001. They have also been approved and classified by the South African Police Service. “We offer a free risk-assessment service to all clients interested in the product, whereby our risk-assessment manager advises suitable installation requirements pertaining to cus- tomer specifications,” says Hughes. He adds that the FST Fire Orb represents the latest advances in fire-extinguishing tech- nology. “The product is far more effective than traditional fire extinguishers, which must be operated manually in order to be effective. In addition, fire extinguishers have no fire-alert activation to warn any bystanders, and are bulky devices that weigh 10 kg to 15 kg on average.” Fire & Security Techniques demonstrated the Fire Orbs at the City of Tshwane’s Winter Awareness Day in the Kopanong Informal Settlement. “One of the many applications of the new technology is fire prevention in informal settlements,” Hughes points out. These not only have a high risk of fires, especially in the cold and dry winter months, but often lack the necessary firefighting equipment and skills. In this regard, the company

MODERN PACKAGING plays an important role in preserving, protecting and selling a host of products, from items tiny enough to need tweezers to be picked up to those that need a forklift to be moved. Packaging also comes in a confusing array of materials and can be very costly if incorrectly selected or processed. Countapulse Controls offers a range of opto-electronic sensors that have been developed to ensure packaging lines operate at peak cost efficiency to the packaging industry. Made by German instrumenta- tion manufacturer Leuze Electronic, the sensors are purpose-designed for the feeding, packing, dosing, detecting, labelling, sealing and other operations that go into the make-up of any packaged product. Modern, high-production packaging uses cutting edge technology, and sensors applied to these ap- plications have to be capable of meeting the demanding requirements. Leuze is a leading developer and manufacturer of opto-electronic systems, which use light in various spectra for sensing, monitoring and controlling products and equipment in the production line. This includes standard opto-electronic sensors, colour sensors, label detectors and sensors for work- place safety. Also in the range are sensors for foil and glass detection, CCD sensors, forked photoelectric sensors and sensors for differentiating between glass and PET. The complexity and depth of sensors available on the market can be confusing, and for this reason, Countapulse Controls can assist customers to evaluate an application for either the fitment of new sen- sors or the retrofit of replacement units.

DHET AND NSF APPROVE ECA(SA) PROPOSAL TO TRAIN 200 ELECTRICAL WIREMEN
DYMO WIRELESS LABEL PRINTER FOR INDUSTRIAL APPLICATIONS
By Mark Mfikoe, National Director, ECA(SA)
M&C REFURBISHES MILL MOTOR FOR GOLD MINE IN ZIMBABWE T he largest ac electric motor operating in Zimbabwe drives a reduction mill and its motor was recently refurbished by leading rotating machinery repairer, Marthinusen & Coutts, a division of ACTOM. Estimated to be around 30 years old, the 2 150 kW synchronous mill motor, which was in operation at Freda Rebecca Gold Mine, suffered a failure caused by age and metal fatigue. The main hub of the electrical rotor component had sheared off. Following preliminary repair work undertaken by the mine, Marthinusen & Coutts was called to site to investigate further and to provide a long-term solution. It was decided, following negotiations with the mine, to do a design modification instead of replacing the hub. Richard Botton, Divisional CEO of Marthinusen & Coutts, explains that this option was chosen as it would save costs and reduce T he Department of Higher Education and Training (DHET) has approved the Electrical Contractors Association’s ap- plication to train 200 unemployed youth as apprentices in the building construction electrical trade with support from the National Skills Fund. The training will not cost the beneficiaries anything. You could, therefore, argue without any trouble that there is indeed free tertiary education and skills transfer in the Republic of South Africa. The aim is to produce electricians who would not only be capable of being employed in the industry but also be employers in the industry and enhance the transformation imperatives of the country. The aim of the project is to turn 200 qualifying persons into registered people, in terms of the Electrical Installation Regulations, by 2020. There will be no shortcuts. Our respect for this trade is too big for us to do anything other than a perfect job. The trust placed on us by the Department of Higher Education and Training to deliver on this project is something we take so seriously that I, as the National Director of this association, will manage the project closely. When we are done, there will be 200 licenced electri- cians unleashed into the industry. Beneficiaries of this project will develop capacity to employ people in South Africa. Given its focus and bias towards the marginalised, without totally neglecting members of other communities, this project will contribute towards the transformation agenda of the Republic and add positively to economic and employment growth, and social development action plans. The geographic spread of the beneficiaries is as follows: There will be 20 apprentices from Brits of which four will be white and 16 black and largely from the rural villages around Brits. We must accelerate transformation. The combined figures in Tshwane and Ekurhuleni consists of 100 of which 20 will be white and 80 black. In Johannesburg, we will have 60 apprentices of which 50 will be black. In Sedibeng we will train 20 apprentices. More than 25% of the beneficiaries will be women, of which 49 of them will be young black women. We will be advertising in various publications, inviting apprentices from these areas to submit their applications. We will priori- tise apprentices with N2 Electrical Heavy Current as a minimum. We will place the apprentices with employers where they will get the opportunity to impress and secure employment and build value-adding relationships. The early bird catches the worm, as the saying goes, so please send your applications to email@example.com. If you are a company owner and would like to take on apprentices in these areas, please email Zinhle and express your interest. With your help, we will be able to resource our industry and complement the existing skilled workforce as we strive for excellence.

the lead time without sacrificing the performance of the refurbished motor. In addition, 18 main pole coils were replaced; these were manufactured by Marthinusen & Coutts at its ISO 9001 accredited facility in Cleveland, Gauteng. A complete rewind of the stator was necessary owing to the extensive dam- age caused during the failure at the mine. “The ability to implement enhancements during the repair of critical electri- cal rotating machinery such as this motor is a major advantage to the mine as it allows for the latest technology and enhancements to be included in the final product solution,” says Botton. The scope of work included the on-site commissioning of the motor which was facilitated by the Marthinusen & Coutts Zimbabwe operation with techni- cal support from the division’s centre of excellence in Johannesburg.

HONEYWELL PRESSURE SENSOR EVALUATION KIT
T he Honeywell SEK001 sensor is ideal for sensor demonstration, testing and evaluation purposes. The SEK001 is essentially an Arduino shield board, which can interface a chosen individual sensor to the Arduino Uno (Rev3) microcontroller board. The selected sensor can either be mounted directly on the SEK001 board, or alternatively con- nected via leads enabling the sensor to be tested in adverse environments, or in a prototype product for proof-of-concept testing. The sensor board does not require the development of code before receiving sensor measurements, enabling devel- opers to start testing and prototyping right away. The kit includes the SEK001 sensor evaluation board and
five jumpers that are preconfigured to evaluate the on-board Honeywell HSCDRRN001ND2A5 5 V dc differential pressure sensor. The SEK001 also has sockets to receive Honeywell’s TruStability HSC and SSC series pressure sensors, which come with an I2C or SPI digital output, as well as the new TruStability RSC series of high-resolution pressure sensors. Also available is free downloadable Honeywell software, which controls the Arduino Uno board and takes readings from the sensor under evaluation. Sensor measurements can be dis- played on a PC and recorded to a .csv file for further analysis.

TRAFO SUPPLIES DRY-TYPE TRANSFORMERS FOR WATER TREATMENT WORKS
cratic Republic of Congo (DRC). The project was managed by SENET which is renown for its engineer- ing excellence. Low Voltage Switchboards used the cubic system supplied by Sabelco which conforms to the latest IEC 61439 specifications. The motor control cen- tres were rated for 550 V, 3 200 A at 70 kVA. The project is one of the largest this year for Low Voltage Switchboards.
T he advantages offered by dry-type or cast resin transformers played a role in Trafo Power Solutions securing an order for thirteen custom designed units. These dry-type transformers are destined for installation in a large-scale Rand Water Zuikerbosch Water Treatment Works.

David Claassen, managing director of Trafo Power Solutions, says it is most gratifying for the company to have received this order only months after the business was established. Claassen, an electrical engineer with broad-ranging and high-level experience in many sectors, recently estab- lished Trafo Power Solutions to distribute and service transformer products from Canada-based Hammond Power Solutions (HPS), in Africa. The contract to supply cast resin transformers for the waste treatment facility will include units that range from 100 kVA to 1 600 kVA. Included in the scope of supply is the complete earth fault protection system that will be in the transformer enclosures. Claassen says that projects go the route of cast resin or dry-type trans- formers for a number of reasons. “Prime among these, is the inherent safety offered by the units as well as ease of installation, given the fact that they are installed inside built substations as opposed to outdoors with as- sociated special bunding and civils.” Dry-type transformers are categorised as F1 in terms of international fire resistance ratings, making them low risk as they are self-extinguishing and flame-retardant by nature. With zero risk of fire, the high safety rating of dry-type transformers allows them to be installed indoors, avoiding the cost and inconvenience of the special structures normally required to ac- commodate the safety and environmental hazards related to oil-filled units. “And this results in savings because there is no need for costly civils and site work to be done,” adds Claassen. Less maintenance is another advantage. Dry-type transformers are low in maintenance and could last for 25 years without significant attention, while oil-filled transformers require regular maintenance, including oil sam- ple analysis to ensure operational consistency and safety.
