ANSI/IEEE 275-1981 - IEEE Recommended Practice for Thermal Evaluation of Insulation Systems for AC Electric Machinery Employing Form-Wound Pre-Insulated Stator Coils, Machines Rated 6900 V and Below

Description: The purpose of this procedure is to classify insulation systems for the machinery within the scope of this standard in accordance with their temperature limits by test, rather than by chemical composition. Data from such tests may be used to establish the temperature classification of new insulation systems before they are service proven. Service proven systems must also be tested according to this test procedure.
