The use of surge capacitors to protect medium voltage induction motor windings from steep-fronted power surges has long been an accepted industry practice. Claims have been made that motor reliability would be improved without the use of surge capacitors if added interturn insulation were incorporated within the motor winding. This paper explores the surge-withstand ability of motors and the surge standards that have emerged. It presents a survey of industry practices and studies related to current motor applications, and provides the motor user with an economic evaluation to arrive at a cost-effective selection of motors with or without external surge protection.
