Due to the influence of the process and production equipment itself, the transformer oil produced contains a certain amount of water, and the external water will enter the transformer oil to varying degrees during the transportation, storage and use of the oil. The water in the transformer oil includes three states: suspended water, dissolved water and deposited water, and the three can be transformed into each other to a certain extent. The presence of water in the transformer oil reduces the breakdown voltage, increases the dielectric loss and acid value, deteriorates the oil quality, and also brings the hidden danger of causing serious failures and affecting the normal operation of the transformer.
