This guide covers general recommendations for loading mineral oil-immersed, 55°C rise, step-voltage and induction-voltage regulators manufactured in accordance with ANSI/IEEE C57.15-1986. Some users may choose to load regulators as though rated for 65°C rise, although this operation is not recognized by ANSI/IEEE C57.15-1986. This guide treats the loss of life to be anticipated under such operation. Loading recommendations in tabular form are contained in this guide. These recommendations cover a wide range of ambient conditions and loss of life. The method and equations used for calculation of the tables are given. This guide is only applicable for regulators having inherent capability to permit the loadings covered.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
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No Superseded Standards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No Inactive-Withdrawn Standards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
