PORTABLE DIAGNOSTIC APPARATUS FOR TESTING CIRCUIT BREAKERS

摘要

A portable diagnostic apparatus for performing diagnostic testing on a circuit breaker includes a number of sensor devices structured to generate a number of sensed parameter signals relating to operation of the circuit breaker during an operational sequence, a number of auxiliary input connectors structured to receive a number of auxiliary data signals from the circuit breaker, the number of auxiliary data signals relating to and being generated in response to the operation of the circuit breaker during the operational sequence, and control and diagnostic circuitry. The control and diagnostic circuitry is structured to control operation of the portable diagnostic apparatus, receive the number of sensed parameter signals and the number of auxiliary data signals, and generate a time signature based on the number of sensed parameter signals and the number of auxiliary data signals.
