Research on Partial Discharge Localization in XLPE Cable Accessories Using Multi-Sensor Joint Detection Technology
نویسندگان
چکیده
A multi-sensor joint detection technology was proposed based on the theory of the high frequency current transformer (HFCT) method, Ultra-high frequency (UHF) method and acoustic emission (AE) method. An experimental partial discharge (PD) testing was applied on XLPE cable with artificial defect signals. The experimental results show that the multi-sensor joint detection technology will help to identify the PD signals from the interference noises and improve the localization accuracy. Streszczenie. Zastosowano wielosensorową metodę badania wyładowania niezupełnego: wysokoczęstotliwościowy transformator prądu oraz metodę emisji akustycznej. Badania przeprowadzono na kablu ze sztucznym sygnałem defektu. Umożliwiło to wydzielenie sygnału z szumów i poprawe dokładności pomiaru lokalizacji. (Badania lokalizacji wyładowania niezupełnego w kablu XLPE przy użyciu techniki multiczujnikowej)

On-line Partial Discharge Monitoring System and Data Processing Using WTST-NST Filter for High Voltage Power Cable
Defects inside insulation of HV XLPE cable accessories can lead to partial discharge (PD) activity. When PD activity happens, leakage current may flow through the grounded line. To acquire the PD current signal, one practicable and effective method is placing a high frequency current transformer (HFCT) winding the grounded line. In order to measure the insulation degradation, a partial discharg...

متن کاملThe Propagation of Partial Discharge Pulses in a High Voltage Cable
Partial discharge within the dielectric of HV solid dielectric power cable greatly shortens the cable life. It is desirable to detect and locate the PD in the cable before breakdown occurs. Understanding the phenomena of propagation of the PD pulse in a power cable is fundamental to the detection and location of PDs. In this paper a power cable model represented by a coaxial transmission lossle...
