What are the types of transformer oil tests?

The types of transformer oil tests include dielectric strength testing, which measures the oil’s insulating properties; moisture content analysis, which determines the water content in the oil; and dissolved gas analysis (DGA), which identifies gases produced by potential faults. Other tests include acidity testing, which assesses the oil’s degradation, and flash point testing, which evaluates fire hazards. These tests are crucial for ensuring the reliability and safety of transformer oil in power transformers.
