Abstract :
This paper proposes a new method of DGA diagnosis, using IEC TC 10 and related databases. We analyzed five gas components (hydrogen, methane, acetylene, ethylene and ethane), which are used for analysis in the standards, with 10 types of gas ratios, and came up with 6 types of gas ratios among them, that can classify faults. Then, we reorganized and analyzed the 6 gas ratios with 15 gas-ratio combinations. From the results, we can suggest a new diagnosis method using 3 gas-ratio combinations that are able to classify fault areas clearly.
