PC57.109 - IEEE Draft Guide for Liquid-Immersed Transformers Through-Fault-Current Duration
Project Details
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.
