Abstract
The authors review the results from an extensive Electric Power Research Institute (EPRI) project on turn insulation capability of motors and also review other publications in order to quantify the surge environment and the surge strength of typical utility motors. The results are compared with standards for the surge strength of motors. The application of vacuum switchgear are surge capacitors is critically examined. Guidelines for new and existing motor installations, a procedure for analyzing surge related failure, and some recommendations for motor manufacturers are provided
