Transformer oils are characterized by purity, oxidation stability and dielectric strength, so that they can have an insulating effect.
Diagnosis of power transformers due to their long-term maturity is critical to your ability and lifetime operation. For this purpose, an analysis method will be wall to determine the state of a transformer. The basis of the analysis systems models of the individual components of the insulation system of a transformer. These include the cellulose layers and the oil.
