620-2022
IEEE Guide for the Presentation of Thermal Limit Curves for Squirrel Cage Induction Machines
A procedure is established for the presentation of thermal limit curves, and guidance for the interpretation and use of these curves for machine thermal protection is provided in this guide.
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No Superseded Standards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No Inactive-Withdrawn Standards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.
620-1996
IEEE Guide for the Presentation of Thermal Limit Curves for Squirrel Cage Induction Machines
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.
