What maintenance is required for oil cooled transformers?

Maintenance for oil cooled transformers involves regular monitoring of transformer oil quality, including tests for dielectric strength, moisture content, and acidity. Additionally, periodic sampling and analysis of the transformer oil are essential to detect any degradation or contamination. Routine inspections of the cooling system, including checking for leaks and ensuring proper circulation, are also critical. Maintaining the integrity of the oil ensures optimal performance and longevity of oil cooled transformers.
