ing a FCL in a transformer feeder location offers great flexibility in reducing substation fault levels to accommodate switchgear ratings. Oneormore FCLs may be installed depending on the fault reduction required and with minimal changes to existing protection settings. A FCL may be included in a transformer protection zone with no additional relaysorCTs required. FCLs may also be used to improve load balancing between feeder transformers with different impedances and/or rated power. FCLs enable
