COUPLING CAPACITOR CONTROL SENSOR Russian patent published in 2018 - IPC G01R27/04 

FIELD: electrical equipment.

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. To achieve the said technical result, a coupling capacitor monitoring sensor is proposed, which includes input and output connectors, a transformer, which primary winding through the input connector is included in the gap between the coupling capacitor bottom plate and the connection filter, a diode bridge, to which the transformer secondary winding terminals are connected, first resistor and two capacitors, connected in parallel and connected to the diode bridge terminals; forming the output current the second and third resistors, one of which is the trimming resistor, which second terminals are connected to the output connector pins.

EFFECT: technical result of the claimed invention is development of the device providing the coupling capacitors condition continuous monitoring at a power facility in order to determine their destruction process beginning, and the corresponding signal generation about this process beginning and development in the current time mode.
