Partial discharging monitoring method and device

The invention discloses a partial discharging monitoring method. The partial discharging monitoring method comprises the steps that data collected by preset ultrahigh frequency sensors are obtained and processed, and a processing result is obtained; when partial discharging warning exists in the processing result, the area, where the corresponding ultrahigh frequency sensor is located, is found according to the processing result; the ultrahigh frequency sensor is used for detecting the area; data of the detection of the ultrahigh frequency sensor are obtained and processed; when partial discharging information exists in the processing result, it is determined that the partial discharging phenomenon exists in the area. The partial discharging monitoring method can improve the reliability of monitoring on partial discharging.
