APPARATUS FOR REMOVING THE PARTIAL DISCHARGE NOISE OF AN ELECTRICAL POWER FACILITY AND APPARATUS FOR DETECTING A PARTIAL DISCHARGE GENERATED SECTION

摘要

The present invention relates to an apparatus for removing the partial discharge (PD) noise of an electrical power facility that is capable of quickly removing noise from a partial discharge signal generated from the electrical power facility such as a gas insulated switchgear (GIS) and the like, and an apparatus for detecting a partial discharge generated section. The apparatus for removing the partial discharge noise of an electrical power facility includes: a partial discharge signal detection unit for detecting a partial discharge signal of the electrical power facility, and detecting and outputting peaks of the partial discharge signal at preset time intervals; a noise signal detection unit for detecting a noise signal from outside the electrical power facility, and detecting and outputting peaks of the noise signal at preset time intervals; and a noise removing unit for removing the peaks of the partial discharge signal positioned at the time intervals identical to the time intervals where the peaks of the noise signal of the noise signal detection unit are positioned, thus quickly and easily removing the noise signal from the partial discharge signal.
