Analysis of alternative parameters of dynamic resistance measurement in high voltage circuit breakers

Analysis of alternative parameters of dynamic resistance measurement in high voltage circuit breakers

Throughout its lifetime, high-voltage circuit breaker (HVCB) contacts suffer from inevitable degradation processes, especially during the formation of electric arcs. Highly degraded contacts can reduce the current interruption capacity and increase the chances of operational faults, which might lead...
