📡 IEEE C57.104 DGA (Duval Triangle 1/4/5 Acetylene/Ethylene/Methane Fault Diagnostic)

Transformer DGA & Duval Triangle Calculator

Evaluate Dissolved Gas Analysis (DGA) in transformer insulating oil under IEEE C57.104 & IEC 60599 using the Duval Triangle method: plot relative percentages of Methane (CH4), Ethylene (C2H4), and Acetylene (C2H2) to differentiate high-energy arcing (D2), thermal faults ($T_1 ext{ to }T_3 > 700^circ ext{C}$), or partial discharge (PD), and diagnostic profits.
