Abstract

Dissolved gas in oil analysis has been used for fault diagnosis of oil immersed insulation. In this paper to improve the reliability in deciding the degradation causes of the oil immersed insulation, we carried out electrical and thermal degradations for the insulations, and analyzed the characteristics of dissolved gases distribution on each situation. As a result more reliable faults discrimination is possible if we use the interrelation of factors like key gases and gas compositions of hydrocarbon gases and ratios of CO/$CO_2$.

본 논문에서는 유침절연에 대한 열열화와 전기적열화 실험을 실시하여 유중가스분석법을 이용한 유침절연의 고장원인 진단에 대한 신뢰성을 향상시키는 방안에 대하여 연구하였다. 유침절연의 고장원인에 대하여 주도가스법과 탄화수소가스의 구성률, CO/$CO_2$비와 같은 진단요소를 단독으로 사용하는 것보다는 진단요소들의 상호관계를 이용하는 것이 유침절연의 고장원인을 신뢰성 있게 진단하는 것으로 나타났다.
