IEEE Recommended Practice for Voltage-Endurance Testing of Form-Wound Bars and Coils

Revision Active STD A comprehensive framework for the voltage-endurance testing of form-wound bars and coils used in large rotating machine stator windings is provided in this recommended practice. The procedures for conducting voltage endurance tests on bars/coils with nominal voltage up to 30 000 V, and operating frequencies of 50 Hz or 60 Hz, are outlined. Power supply and voltage requirements, test set-up, specimen preparation, pre-test evaluation methods, as well as temperature and voltage application and measurement methods are specified. Guidelines for failure investigations, suggested test records, and test report requirements are provided.
