Breaker Analyzer Control

Breaker analyzer control is an application to control PME-X00-TX devices

The PME family of circuit breaker analyzers combine portability, ease of operation and remarkable accuracy for the task of evaluating the condition and performance of medium and high voltage three phase circuit breakers of any kind.

These small, lightweight yet sturdy instruments will record the transition of the circuit breaker’s poles between OPEN and CLOSE positions with a resolution of 0.1 milliseconds to reveal graphically and numerically any unbalance or misallignment in the three phases. Another two auxiliary inputs allow the recording of the activity by other moving contacts during the same analysis to provide additional information about the syncronization of important elements in or outside the circuit breaker itself. The recording process can be triggered by the user or by the change of status of a voltage or dry contact signal. The duration of OPEN and CLOSE commads can be set to accurately match that of the circuit breaker’s control device, in order to test the machine’s driving mechanism against requirements.

Breaker analyzer control is an application to control PME-700-TX and PME-600-T devices:

1) Open / Close time measurement in main and auxiliary contacts.

2) Graphical and numerical evaluation of coil currents.

3) Three-phase, 4-wire measurement of contact resistance.

4) Substation’s auxiliary DC supply condition evaluation.
