Motors and their associated equipment must be protected against both overload and overcurrent (short circuit or ground fault). This function is usually split, with ...

Thanks to ongoing innovations in technology, electrical engineers' approach to motor protection has changed over the years. The traditional strategy to large AC motor protection (e.g., over 500 hp), ...

Electronic overload protection has long been employed on industrial electric motors. In some cases, this internal protection may serve as a viable torque limiting mechanism. Many applications, however ...
