FSA를 적용한 초고압 지중송전 XLPE케이블의 부분방전 진단기술

Partial Discharge Diagnosis technology of EHV Underline Transmission XLPE cable applied FSA

We studied the improved detecting method on Partial Discharge occurred in EHV power cable. In this field, we usually applied the several sensor for partial discharge. This is metal foil employed with the capacity foil-sensor. We detected the partial discharge through regularly array standard foil-sensor for the better improvement of existed foil-sensor in this research. This test is progressed in real EHV liveline, we analyzed that compare existed foil-sensor to detect character of FSA(Foil Sensor Array) for this test. From this result, detective character of fabricated FSA showed better result than existed foil-sensor.
