GIS 부분방전 검출을 위한 UHF 신호측정법 현장 적용

  • Published : 2000.07.17

Abstract

Laboratory experiments and on site measurements were conducted to detect partial discharges in GIS(Gas Insulated Switchgear) using the UHF(Ultra High Frequency) technique that has been applied many places in the world. Experimental results were in good agreement with calculation in locating a partial discharge source using mock-up GIS. Defect type and its location were inferred after a measurement on 345 kV GIS that showed some abnormal phenomenon. Precise examination inside the GIS coincided with the results inferred from the measurement. High reliability of UHF technique for site application was confirmed.
