A Comparative Diagnosis Approach on Transformers Insulating Oil
The immersed oil power transformer is so vital equipment in power system that maintenance-engineers take more cautious on transformers insulating oil as the criterion of maintenance.The dissolved gas analysis (DGA) is known for an effective technique to detect transformers incipient faults.In this paper,a practical method is presented that it took the data of Past Fault Record and ANSI/IEEE C57.104 Standard Rule to combine an approach by EXCEL software to diagnose transformers insulating oil.The user only keys H2,CH4,C2H2,C2H4,and C2H6 those gases were decomposed via ASTM-D3612.The diagnosis result was showed in texts and the plotted figures through Pearson product moment correlation coefficient.This paper took some dates from Taiwan Power Company to verify that is validation and accuracy on the transformers insulating diagnosis approach.
