Transformer Oil Filtration - is it good or bad?

A static device which transfers electrical energy from one circuit to another through the process of electromagnetic induction is know as Transformer. It is most commonly used to increase or decrease voltage levels between circuits. Since transformer oil also know as insulating oil works as a coolant also, so it has to be stable at very high temperatures, in both electrical and chemical conditions. Therefore, the transformer oil must have a high flash point of about 140° Celsius or higher, a low pour point of about -30° Celsius or less, and a dielectric breakdown voltage of about 28 to 30 kilo volts or higher. Advantages of Transformer Oil Filtration The transformer oil filtration becomes necessary as with time the transformer oil or insulation oil gets contaminated with dirt, moisture and dissolved gases. The timely and regular filtration of transformer oil ensures longer transformer's life. Transformer oil filtration process not only maintains but also increases its
