“…For transformers, Islam et al [50] present the diagnosis of several transformer faults using dissolved gas in oil analysis (DGA) and an FLS for its interpretation. An overview of different FLSs for DGA is presented in [51], where it is indicated that there is not a single technique that can enable the detection of the full range of faults, therefore the combination of different methods has to be explored as a promising solution. Although promising results have been obtained using FLSs, a relatively high superiority of an adaptive neuro fuzzy inference system for DGA is presented in [52], obtaining an accuracy of 98% for all the 100 fault cases under study, while FL obtained 95%.…”

“…C 2 H 2 /C 2 H 4 and CH 4 /H 2 ratios provide a good discriminating power with respect to thermal faults and discharge faults; C 2 H 4 /C 2 H 6 and C 2 H 4 /CH 4 ratios perform well in distinguishing between low-, medium-, and high-temperature thermal faults; C 2 H 2 /C 2 H 4 and C 2 H 4 /C 2 H 6 ratios are suitable for distinguishing between medium-temperature and high-temperature thermal faults. C 2 H 2 /C 2 H 4 and C 2 H 4 /C 2 H 6 ratios are good indicators to distinguish partial-, low-, and high-temperature discharge faults [4,17,22,[48][49][50].…”

“…The improved/new three-ratio (IEC three-ratio) and Dornerburg method are effective methods for oil-immersed transformer fault diagnosis, being easily implemented and widely used. These traditional DGA methods mainly use operational experience and expert knowledge to establish the diagnosis rules of "code-fault type" based on the ratio (or content) of dissolved gas and fault types, but these methods suffer some drawbacks in their engineering applications, such as their code boundaries being excessively absolute and faults not being completely covered by the defined codes [4,5].…”
