Fault Diagnosis System of Transformer Based on GAS Chromatography

In a certain extent, the gas component and content dissolved in the transformer oil indicate the insulation aging and fault degree of the transformer. The fault diagnosis system of transformer based on gas chromatography applies the analysis method of gas chromatography to transform each of the concentration into corresponding electric signal. After data processing, the signal is transmitted into working station to form chromatogram and made a fault diagnosing with grey relational theory. The system can detect the gas component, content, and speed of gas producing. It can find out the potential fault in the transformer as soon as possible and forecast the development trend of fault to ensure safe and economical running of the transformer
