The PME 700 TR combines 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.

A comprehensive range of options will let you choose the combination that best accommodates your technical needs as well as your budget.
