SparksElectricalNews#WozaDecember

We are at the time of year when we are all counting the days till December, more specifically, 15 December when many companies will be closing for a well-deserved, end-of-year break.

To celebrate the holidays and to welcome the year end, our generous advertisers have donated a wonderful selection of gifts which include two Samsung Home Entertainment Systems; a Genmart 7.5 kVA generator blue; and a host of useful, top quality tools; multimeters; and lamps.

To stand a chance of winning one of these gifts, simply email your name, company name, postal address and telephone number to promotions@crown.co.za. Only one entry per person please. Neither Crown Publications’ staff nor the advertisers’ agencies will be eligible for the draw.

Entries close at 17h00 on 16 January 2018. The advertisers who donated the gifts will join the Sparks team on 17 January to draw 21 lucky winners, whose names will be published in our February issue.

Personality of the Month

For Ian Greyling, CEO of Electrahertz, mistakes are part of the game and he identifies a great player by how well he or she recovers from them. A people’s person, he is passionate about training and development, and if he ‘could do it all over again’, would spend even more time involved in skills development within the electrical industry as he firmly believes the field offers a great background from which people can spread their wings into many different areas. Ian has successfully run Electrahertz for 35 years and still enjoys solving problems for customers. He plans for the future include flying a helicopter, sitting atop Mount Everest, fishing in Alaska and seeing the Northern Lights.

Column: Transformers... not as simple as they seem

To end off the year, Terry Mackenzie Hoy discusses transformers in electrical installations and reminds us that when it comes to transformers, all is not as simple as it seems. There are three broad categories of transformers, namely, power distribution transformers, voltage transformers and current transformers. Power transformers are made to SANS specification SANS 60076-1:2011 Power transformers – Part 1: General. 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 and most distribution transformers have a primary voltage rating of 6 600 V, 11 000 V, 22 000 V or 33 000 V, three-phase. Terry outlines the variations in power distribution construction and provides a checklist of things to bear in mind.
