CONNECTION FILTER WITH INTEGRATED COMMUNICATION CAPACITOR MONITORING SENSOR Russian patent published in 2020 - IPC G01R27/00 G01R31/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment and is intended for the coupling capacitors at power facilities condition monitoring, can be used to determine the coupling capacitor destruction process beginning and its timely replacement. Disclosed is a connection filter with an integrated monitoring sensor of a coupling capacitor, consisting of a transformer, one of whose winding leads is connected to a coupling capacitor, and the other is grounded. At that, the transformer is equipped with an additional separate winding, to which the communication capacitor monitoring sensor is connected.

EFFECT: simplified monitoring system of communication capacitors state due to creation of connection filter, which is part of the above system, with integrated sensor of control of communication capacitor.
