Direct and automatic measurement of the overlapping time in GCB applications


The overlapping time of double-contact circuit breakers is defined as the time delay elapsing between the opening of the nominal and the arcing contacts. It is an important criteria for the circuit breaker lifetime. It is usually determined indirectly on live breakers, e.g. derived from the number of breaking operations and the interrupted current amplitude… (More)
