Method and apparatus for detecting failure of an actuator switching device

Method and apparatus for detecting failure of an actuator switching device

A circuit breaker includes an actuator, a switching device connected to the actuator, and a test unit configured to test a connection between the actuator and the switching device by detecting a first connection voltage at the connection between the actuator and the switching device. The test unit i...

description A circuit breaker includes an actuator, a switching device connected to the actuator, and a test unit configured to test a connection between the actuator and the switching device by detecting a first connection voltage at the connection between the actuator and the switching device. The test unit is further configured to test the operation of the switching device by turning the switching device on without operating the actuator.
