Guidance in applying relay protection to squirrel-cage and wound-rotor induction motors and synchronous motors is provided. The generally accepted forms of motor protection are reviewed, and the use of relays and devices, singly and in combination, is summarized so that the user can select the necessary equipment to obtain adequate motor protection. This guide is concerned primarily with the protection of three-phase integral horsepower motors and variable-speed motors where specifically indicated. It does not detail the protective requirements of all motors in every situation. The recommendations are of a general nature, designed to cover the usual or typical motor installations.

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No Superseded Standards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No Inactive-Withdrawn Standards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
