Abstract

See full text

A testing system includes a truck carrying a circuit breaker, a fixed contact, and an actuator piston connected to a movable contact. A test platform supports the truck in a contact testing position and includes a sensor circuit mounted on the test platform and positioned under the truck and aligned with the circuit breaker when the truck is on the test platform in the contact testing position. The sensor circuit is configured to acquire displacement data of the actuator piston when the movable electrical contact is moved between the open and closed positions. A controller is coupled to the sensor circuit and configured to receive the displacement data and determine electrical contact erosion within the circuit breaker.
