Switching Systems (Pty) Ltd Unclaimed

As an industry leader in industrial electronics, Switching Systems was approached in 1989 by ESKOM to develop a solution to problems they were encountering within their own power plants due to voltage dips. Currently the fifth largest utility in the world, they were experiencing drives and motors tripping due to voltage dips caused primarily by short circuits. They had suffered many trips on large fossil generating units and even tripping of complete power stations due to short circuits in the 22kV switchyard. The depression in supply voltage to the auxiliary system resulted in the contactors dropping out, stopping drives, which are critical to the continuous running of the generating units.
