Factors such as electrical or thermal stress and chemical contamination cause malfunctions in transformers. Transformer oil is especially important in the cooling of transformers. Transformer oils must pass tests and analyzes for some reasons:
- Determination of basic electrical properties
- Determination of the suitability of the oil for use
- Increasing component life
- Reducing oil cost
- Detection of the wear condition of the transformer
- Electrical or thermal faults
- Determination of oil quality
