Dissolved Gas Analysis (DGA) of transformer oil is a key parameter in predictive maintenance due to its ability to "read" the internal conditions of the transformer without requiring dismantling or stopping operation. Here's a complete explanation: 1. Early Detection of Internal Faults• Dissolved gases (H2, CH4, C2H2, C2H4, C2H6, CO, CO2) are formed due to the degradation of oil or solid insulation due to heat, excess current, or electrical discharge.• Certain gas patterns ind...
