Chromatographic Analysis of Transformer Oil Based on the Three-ratio Method
It is an important work to study the online monitoring of the transformer,timely find the abnormal state of the transformer and make fault diagnosis,and reduce the consumption of human and financial resources,but also effectively guarantee the safe and reliable operation of the transformer.The paper studies the principle of gas pro-duction in oil,the sampling process and degassing process of transformer oil,and analyzes the oil chromatography of different operating states based on three-ratio method.The study shows that the transformer fault type can be effec-tively diagnosed by the three-ratio method.
