Abstract

Discusses the current transformer performance and the effect that the direct current (dc) component of an assymetrical fault current will have on current-operated protective relays. Effect of the dc tail on the fault-detector function of the relay; Different reaction of two specific breaker failure relays under the same input waveform.
