APPARATUS FOR MEASURING PARTIAL DISCHARGES Russian patent published in 2021 - IPC G01R31/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in high-voltage electric power networks. Proposed is an apparatus for measuring partial discharges, containing a static converter intended to supply voltage to the tested object, equipped with a discharge sensor, connected whereto via a connector is a first interference-resistant wire pair connected at the other end to the measuring apparatus through a filter with one conductor, a second noise-resistant pair linked with the second connector, connected to the input whereof is a capacitor, the capacitance whereof is equal to the capacitance of the sensor, both wire pairs are located nearby, wherein connected to the second end of the conductors of the second pair is the primary winding of the transformer, the secondary winding whereof is included between the output of the second conductor of the first pair and the second input of the filter.

EFFECT: provided effective measurement of partial discharges.
