Investigations on the dielectric behavior of vacuum circuit breakers after switching operations (original) (raw)

24th ISDEIV 2010, 2010

Abstract

The dielectric behaviour of vacuum interrupters (VI) before and after switching operations has been investigated. At first, switching operations with different intensities of load with short circuit currents at 50Hz frequency were performed. The test objects were a standard VI with a rated voltage of 12kV, a rated current of 1250A and a short circuit interruption current of 20kA. In
