Abstract
An arc flash mitigation system for use with a generator excitation system is provided. An exemplary arc flash mitigation system includes three semiconductor fuses, three current transformers, an overcurrent detection circuit, a gate firing circuit, and three pairs of thyristors respectively arranged in an anti-parallel phase-to-phase configuration. An exemplary method includes detecting an overcurrent and providing a gate signal to each of a plurality of thyristors included in a crowbar circuit.
