摘要：

On-site Partial Discharge detection on XLPE cables accessories is very difficult because of pulse noise interference, such as pulse interference created by automobile ignition coils on the street, etc. A suitable solution for the monitoring of cable accessories during operation is a sensitive on-site PD detection method. This can be realized in an advantageous way with combinatorial sensors, an antenna sensor, a UHF sensor, and two VHF split-core PD sensors. These sensors are not connected to the high voltage directly, a UHF sensor can be placed near the cable joint and two split-core sensors can be installed on both sides of the cable joint easily and safely. The detection making several windows in the time domain towards multiple wide-band pulse signals can achieve reliable discrimination of real internal PD and external noise under noisy on site conditions. More than twenty cases of on-site PD detection for HV XLPE cables have been proven this way. This method has high detection sensitivity and high noise recognition ability.
