PC37.96
Guide for AC Motor Protection

This application guide presents generally accepted methods of protection and monitoring of ac motors. It identifies and summarizes the functions necessary for adequate protection of motors based on type, size, and application. The methods discussed in this guide are based on typical installations. Information relating to protection requirements, including microprocessor-based protection systems, applications, and setting philosophy is provided to enable the reader to determine required protective functions for motor installations. Relay protection of squirrel-cage, wound rotor induction motors, and synchronous motors is presented herein. This guide also summarizes the uses of relays and devices, individually and in combination, so the user may select the necessary equipment, to obtain adequate motor protection. This guide is concerned primarily with the protection of three-phase integral horsepower motors and motors associated with adjustable-speed drives. This guide does not purport to detail the protective requirements of all motors in every situation. What it does provide is enough information and guidance for the user to implement adequate protection for most applications.
