Full Description

New IEEE Standard - Inactive-Withdrawn.Recommendations for the application of overcurrent protective devices to limit the exposure time of dry-type transformers to short circuits are provided. The transformer coordination curves in this guide pertain to the temperature rise of the windings during time intervals less than 100 s, wherein nearly all the heat generated is stored in the conductors.
