IEEE Std C37.96-2000 Guide for AC Motor Protection

Power System Relaying Committee of the IEEE Power Engineering Society.
Approved 30 March 2000 IEEE-SA Standards Board.Generally accepted methods of protection for ac motors are provided. This guide identifies and summarizes the functions necessary for adequate protection of motors based on type, size, and application. This guide does not purport to detail the protective requirements of all motors in every situation.Keywords: AC motor protection, adjustable-speed drive motor protection, induction motor protection, microprocessor-based motor protection, motor, rotating machinery protection, synchronous motor protection, wound rotor motor protection C37.96-2000ScopeAC motor terminology glossary
