Abstract
There is provided a method for measuring abnormality detection parameters of a disconnect switch, comprising: releasably connecting a first sensor to the disconnect switch, the first sensor adapted to measure a first parameter related to a position of an arm of the disconnect switch, the disconnect switch comprising a rotating actuation element operatively connected to the arm for moving the arm between a closed position and an open position; releasably connecting a second sensor to the rotating actuation element, the second sensor adapted to measure a second parameter related to a torque of the rotating actuation element; moving the arm using the actuation element; measuring and storing in memory the first and second parameters while the arm is moving; and disconnecting the first and second sensors.
