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.
