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.

No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
