ABSTRACT:
A method for recording and having analyzed waveform data associated with an electronic circuit breaker having an electronic trip unit is disclosed. The electronic trip unit has a communication port and is capable of providing to the communication port a first signal representative of a phase current passing through the circuit breaker, and a second signal representative of a conditional event at the circuit breaker. The method includes facilitating the connection of a waveform recorder device to the communication port of the electronic trip unit; facilitating recording in a first memory of the waveform recorder device in a circular queue fashion information relating to the first signal received from the electronic trip unit; and, in response to the second signal received from the electronic trip unit, facilitating the stopping of the recording in the first memory.
