Disclosed herein is an approach that uses a motor protection system to protect a process operation. In one aspect, a motor protection system in conjunction with a controller monitor the performance of redundant motor-driven prime movers having a lead motor-driven prime mover and a lag motor-driven prime mover. In one embodiment, the controller controls operation of the redundant motor-driven prime movers as a function of motor protection measurements generated from the motor protection system. In particular, the controller uses the motor protection measurements to determine if the lead motor-driven prime mover is in distress. The controller activates operation of the lag motor-driven prime mover in response to determining that the lead motor-driven prime mover is in distress. In one embodiment, the controller activates operation of the lag motor-driven prime mover prior to tripping the distressed lead motor-driven prime mover.
