VOLTAGE SAMPLING CABINET (VSC) WITH INTEGRATED COMMUNICATION CAPACITOR MONITORING SENSOR Russian patent published in 2020 - IPC G01R27/26 G01R17/02 H01G13/00 

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. Essence of the disclosed solution is that the voltage sampling cabinet (VSC), the input of which is connected to the output of the communication capacitor, and the output to the connection filter, includes two transformers, one intended for feeding synchronism devices, another for supply of synchronism monitoring relay and voltage, wherein one of transformers is equipped with additional separate winding, to which is connected sensor of coupling capacitor, consisting of diode bridge, to which are connected outputs of additional separate winding of transformer VSC, first resistor and two capacitors connected in parallel and connected to outputs of diode bridge, second resistor, which generates output current, output connector, to contacts of which sensor output is connected.

EFFECT: simplifying the process of monitoring the condition of communication capacitors by creating a voltage sampling cabinet (VSC) with an integrated sensor of monitoring a communication capacitor.
