About This Duval Triangle Calculator

TriboTech's Duval Triangle tool includes all 7 triangle variants in a single interface, making it the most comprehensive free DGA interpretation tool available online. This tool implements the latest CIGRE 2023 corrections including refined arcing sub-zones (D1-H, D1-P, D2-H, D2-P) and the OC-zone toggle for mineral oil carbonization detection.

Triangle 1: Primary mineral oil analysis (CH4, C2H4, C2H2)
Triangle 2: OLTC (On-Load Tap Changer) diagnostics
Triangles 3 & 3b: Alternative fluids (Silicone, Midel 7131, FR3, Biotemp)
Triangles 4 & 5: Low-temperature and thermal fault refinement
Triangles 6 & 7: FR3 natural ester specialized analysis
