Water in transformer oil leads to a number of undesirable consequences:
– reduced dielectric strength and partial discharge stability;
– intensive aging of paper insulation;
– acceleration of oil oxidation;
– increased formation of carbon with electric arcing;
– increased corrosion of transformer metal parts caused by the oil;
– reduced fluidity of the oil at higher temperatures.
These can be avoided by scheduled moisture content control and transformer oil dehydration.
