Abstract
There is provided a method for determining an abnormality during operation of a high voltage disconnect switch, the method comprising: determining a current position of an arm of the high voltage disconnect switch operatively connected to a motor, the motor being operated for driving the arm of the high voltage disconnect switch; determining a torque of the motor corresponding to the current position of the arm; comparing the torque of the motor to a torque threshold for the current position of the arm; and outputting an abnormality signal based on the comparison.
