Abstract: There is provided a system and method for detecting an abnormal operation of a motor controlling an operating parameter of a machine. Both a torque of the motor and the operating parameter are monitored. A memory stores a plurality of predetermined torque values indicative of a normal operation of the motor. A plurality of operating parameter values are also stored in the memory with each operating parameter value having a corresponding predetermined torque value associated therewith. The predetermined torque value corresponding to the monitored operating parameter is retrieved from the memory and compared to the monitored torque value to detect an abnormal operation of the motor.

Abstract: A system for controlling a high voltage switch having at least one connect/disconnect arm, the system comprising: actuating means for displacing the at least one connect/disconnect arm; an optical position sensor for determining a position of the at least one connect/disconnect arm; and a control module operatively connected to the actuating means and adapted to dynamically adjust a speed of motion of the at least one connect/disconnect arm as a function of the position of the at least one connect/disconnect arm.
