Active Standard

IEEE C57.109-2018

IEEE Guide for Liquid-Immersed Transformers Through-Fault-Current Duration

Recommendations believed essential for the application of overcurrent protective devices applied to limit the exposure time of transformers to short circuit current are set forth. Transformer coordination curves are presented for four categories of transformers. There is no intent to imply overload capability.
