On-line Pd Spot Testing and Continuous Monitoring for in Service Power Cables – Techniques and Field Experiences
نویسندگان
چکیده
Applications of on-line PD spot testing and monitoring for in service power cables are presented. The motivation and advantages of the on-line approach to the cable insulation assessment are covered. The different aspects of PD testing are discussed: detection, location and continuous monitoring. The test techniques for different types of transmission and distribution cable circuit are shown with field examples. Integration of continuous monitoring with existing test techniques such as off-line testing and PD localisation is also shown.

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...
