isolated neutral is presented. The method uses controlled switching and requires independent-pole-operated circuit breakers. Two switching operations are proposed at time instants that achieve optimal mitigation of inrush current.
Abstract
In this paper, a new method for inrush current mitigation of three-phase transformers with isolated neutral is presented. The method uses controlled switching and requires independent-pole-operated circuit breakers. Two switching operations are proposed at time instants that achieve optimal mitigation of inrush current.
