Schneider Electric South Africa has teamed up with the French Ministry of Education and the Vaal University of Technology (VUT) to launch a centre aimed at developing programmes to train technicians and higher technicians in the fields of energy, electricity and maintenance of automated systems. Named the French–South African Schneider Electric Education Centre (F’SASEC), the new facility is in line with the Department of Higher Education and Training’s vision of accelerating artisan training across the country and will focus on preparing young South Africans from disadvantaged backgrounds for the job market… (more)

System planning is the Achilles’ heel of a data centre physical infrastructure project. Planning mistakes can magnify and propagate through later deployment phases, resulting in delays, cost overruns, wasted time, and ultimately a compromised system. Much of the trouble can be eliminated by viewing system planning as a data flow model, with an orderly sequence of tasks that progressively transform and refine information from initial concept to final design… (more)

Today’s rapidly evolving industrial climate demands machines that are compact, inexpensive and easy-to-use. The system integrator is put in the position of providing the marketplace with machines that meet these criteria quickly… (more)

Over the past few months there has been much written about renewable energy, more efficient use of energy, sustainability and many similar buzz words. Perhaps the reality for us in South Africa is the fact that electricity is now expensive and this is starting to affect our pockets and companies’ bottom lines.It is ironic that for a nation that considers itself environmentally conscious, it has to be the effect on our pockets that spurs us on to take some action… (more)
