متن کاملOn-line Partial Discharge Monitor System of XLPE Power Cable Based on Virtual Instrument
High voltage XLPE power cable is a very important part of power system. The degree of electric-tree aging in the cable can be estimated effectually by measuring partial discharge. An on-line partial discharge monitor system of XLPE power cable was developed based on the virtual instrument designing conception. This system has the advantage of wide analog bandwidth, excellent anti-interference a...
متن کاملDSP Based On-line Partial Discharge Monitoring System for High Voltage Power Cable
In high voltage power cable system, partial discharge (PD) is a common phenomenon which reflects the degradation of insulation. When partial discharge happens inside the cable, leakage current will flow through the grounded conductor. To couple the partial discharge current, one feasible and effective method is placing a clamp-on high frequency current transformer around the grounded strap. In ...
متن کاملOn-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...
