The amount of dissolve gases liberated in transformer oil produces different faults. Various gases are evolved in transformer. Various methods are used to analyse the faults in transformer like Rogers Ratio Method (RRM), Doernenburgs Ratio Method (DRM), Duval Triangle Method (DTM), Duval Pentagon Method (DPM), and IEC Ratio Method (IRM). The percentage of gases dissolve in oil may lead to different faults on transformer. The health of transformer majorly depends on the state of transformer oil.
