In 2011 we had started to negotiate with distribution untility PRE to integrate regular testing purposes by installing Cicuit Breakers from vaious suppliers. By mid of 2011 we performed on site at 110kV s/s in Prague a demonstration of KoCoS Test and Measurment system – ACTAS, in combination with PROMET, to perform a total circuit breaker test.

The 110 kV circuit breaker had been tested successfully, according customer requirements and needs.

This frequent testing will help PRE in evaluating their technical need on each circuit breaker → fast, easy and cost effective.
