IEEE C57.12.59:2015

Revision Standard - Active.
Recommendations believed essential for the application of overcurrent protective devices that limit the exposure time of dry-type transformers to short-circuit currents are set forth in this guide. This guide is not intended to imply overload capability.

This guide for dry-type transformer through-fault current duration applies to dry-type distribution and power transformers built in accordance with IEEE Std C57.12.01.
