Vacuum Arc Commutator for Resistive Fault Current Limiter. Final Report

摘要

A triggered vacuum arc commutating switch, based on magnetic modulation, has been evaluated for application to a resistive fault current limiter at transmission voltages. A self-contained turn-on, turn-off switch has been demonstrated for the multi-MW power level. Up to 9 kA have been interrupted. Transient recovery voltages ranged up to 20 kV. Parallel shunt capacitance increases the interruption ability, particularly at higher source voltages. (ERA citation 05:013536)
