Abstract

Oscillating voltage is an effective method for PD detection in XLPE cable. In this paper, it mainly described the principle of oscillating waveform test system (OWTS) for PD detection and proposed the peak-correlation method for the location of partial discharge points. Then, an oscillating waveform test system for 10kV cable was established in the laboratory. It was used for the PD testing of a 500 meters long cable. In the end of the paper, the waveform characteristics of the direct pulse and reflect pulse were analyzed. With this feature, the problem caused by multi PDs in a single time window could be effectively solved which greatly improved the reliability and automation of the PD location algorithm. Experimental results show that oscillating voltage can effectively excite the generation of partial discharge and peak-correlation is a valid method for PD location with sufficient accuracy and reliability.
