What maintenance is required for oil filled transformers?

Maintenance for oil filled transformers includes regular monitoring of transformer oil quality, including tests for dielectric strength, moisture content, and acidity. Additionally, periodic sampling and analysis of the transformer oil can detect contaminants and degradation. Routine inspections of the transformer’s physical condition and ensuring proper cooling and ventilation are also essential. Maintaining the integrity of seals and gaskets helps prevent oil leaks, ensuring the reliability of oil filled transformers.
