APPARATUS FOR NOISE GATING FROM PARTIAL DISCHARGE AND DETECTING PARTIAL DISCHARGE AREA OF POWR EQUIPMENT

摘要

PURPOSE: An apparatus for noise gating from partial discharge and detecting partial discharge area of power equipment are provided to detect easily the part discharge generation section of the electricity in the device. CONSTITUTION: The partial discharge signal detector(10) detects the partial discharge signal of the electric power equipment. The peak of the partial discharge signal is detected according to the preset time interval. The noise signal detector(20) detects the noise signal at the outside of the electric power facilities and detects the peak of the noise signal according to the preset time interval. The noise eliminator(30) eliminates the peak of the partial discharge signal locating in the same time interval as the time interval of the peak of the noise signal detection unit.
