Effect of Water On the Characteristics of Insulating Oil Appliances

    Sep 12, 2018

The transformer insulation system is composed of insulating paper and insulating oil, both of which are inseparable. The harm of water on insulating oil is very serious. Water in oil will accelerate the deterioration of oil, making its electrical performance deteriorate and lowering the electric strength. This is also a necessary reason to use the Transformer Oil Purifier.

Transformer Oil Purifier

What is the effect of water on the electrical properties of the insulating oil under normal circumstances?

When the water content of oil is greater than 15uL/L, the breakdown voltage decreases rapidly with the increase of water content, which is related to the solid impurity in oil. Because engineering oil always contains a certain amount of solid impurity, if the oil is not affected by moisture, even if there is solid impurity, because its dielectric coefficient is not much larger than the oil's dielectric coefficient, it is difficult to form a small bridge, so the impact on the oil breakdown voltage is not significant. When the impurity is affected by moisture, the breakdown voltage will be significantly reduced. The breakdown electricity of oil not only decreases with the increase of water content and impurity quality, but also relates to the properties of solid impurities. The biggest threat to paper insulation is when water and fiber impurities are present in oil.
