About This Item

 

Full Description

Scope

Squirrel Cage Induction Motors, 250 HP and above and designed for specified load an application conditions will be covered.

Purpose

The purpose is to define thermal limit curves and to establish a standard procedure for the construction and presentation of these curves. The working group will also attempt to harmonize this standard with ANSI/IEEE 37.96. This guide will replace the ANSI/IEEE Std. 620 (Trial Use Guide).

Abstract

Revision Standard - Inactive-Reserved. The purpose of this standard is to define thermal limit curves and to establish a standard procedure for the construction and presentation of these curves. The working group will also attempt to harmonize this standard with ANSI/IEEE 37.96.
