Oil testing in traction transformers involves collecting oil samples and analyzing them for indicators of transformer health. Key tests include Dissolved Gas Analysis (DGA) to detect gases produced by insulation breakdown, moisture content measurement, acidity testing, and dielectric strength assessment. The results help identify issues like overheating, insulation degradation, and contamination. Regular oil testing is crucial for predictive maintenance, allowing operators to address potential problems before they lead to transformer failure.
