Abstract: This paper describes a new ac-dc current-shunt calibration system with a current range of 1 mA-100 A and a frequency range from 10 Hz to 100 kHz. The new system consists of an ac-dc ...

Abstract: The dielectric recovery strength (DRS) of vacuum circuit breaker (VCB) interrupter is closely related to the travel characteristic of contact, which determines the overvoltage caused by ...
