The analysis is done after the extraction of the gases and a gas chromatography thereafter. The aim of the analysis is an early determination of aging and functional problems of the transformer. 모든정량분석은 변압기 오일을 용해하는것입니다. 이 분석은 가스의 추출과 가스 chromatography thereafter 를 한후에 이루어 집니다. 이 분석의 목표는 변압기의 노화와 기능적결함을 초기에 진단하는 것입니다.
