PME 500-TR
We offer for rent a testing device for high-reliability circuit breakers, recognized for its operational simplicity and ability to perform a complete analysis of the functional status of power circuit breakers.
It has the following features:
Measurement of the closing and/or simultaneous opening time of up to 3 main contacts and 2 auxiliary contacts, including pre-insertion resistances, if any.
Evaluation of the synchronism between the switch poles.
Determination of maximum currents and operating times in both closing and opening coils simultaneously.
Evaluation of the status of the substation’s auxiliary power batteries based on the coil consumption graph.
Automatic determination of the resistance of the three main contacts.
