On Line Monitoring of Partial Discharge in High Voltage Cables
Abstract: Now China vigorously
develop urban underground cable, the scale of the underground power grid is
gradually expanding, the voltage level of the high voltage cable from the
original 23 35kV to kV, and then to 110kV and even 220kV rising. In cable
trench, different levels of voltage cable mixed, ditch perenniallyhumid, even
perennial water and power cable trench no monitoring equipment for use, thus
for on-line monitoring caused a lot of difficulties. On line detection is the
key technology for signal extraction and anti interference technology. In this
paper, a scheme of real-time partial discharge on-line monitoring for high voltage
cables is designed.
Keywords: Real time partial
discharge on-line detection, High voltage cable, Signal extraction technique, Anti
interference technology
