Maintenance requirements for oil-filled transformers include regular visual inspections to check for leaks, signs of corrosion, and any unusual odors that may indicate problems. Routine tests on insulating oil, such as DGA (dissolved gas analysis) and moisture content assessments, help monitor the condition of the oil. The oil also requires periodic filtration or purification to remove particulates and moisture, thus ensuring optimal performance and longevity. Additionally, maintaining appropriate cooling systems and ensuring that temperature remains within operational limits is crucial for extending the oil filled transformer life expectancy. Lastly, electrical testing such as power factor testing and transformer turns ratio testing should be conducted to assess the electrics and ensure proper functionality.
