A question for many is what transformer oil is, what it consists of and what are its main functions inside the transformer. Transformer oil is a type of insulation oil made by fractination of crude oil. It mostly consists of parrafin, saturated oil hydrocarbons and many other components.
The main functions of transformer oil are:
Insulation. Transformer oil is a better dielectric than air. Insulation covered with oil not only performs better, but is also protected from erosion.
Heat dissipation. Transformer generates a lot of heat, so the oil is used as a coolant. The oil is essential to correct operation of a transformer.
Transformer oil is essential for arc interruption and extends transformer lifetime.
The most common contaminants, apart from gas, are water and solid particles. Degassing also helps to remove water molecules from the oil.
The first question is why transformer oil degassing is necessary? The gases solved in the oil can cause sparks, arcing, corona and, of course, overheating, which degrade equipment efficiency and shortens transformer service life. Besides, water in the oil decreases oil’s dielectric strength.
In the future, with the ever increasing standard requirements for distribution transformers, the need for efficient degassing will continue to grow. Gas exists in the oil in the form of separate or attached molecules, invisible to the naked eye.
The main technique for removal of gas from the oil is pressure decrease. As pressure drops, the molecules gather together and the gas starts to form into bubbles. The bubbles grow as pressure decreases and float to the oil’s surface or are pushed through the coagulant.
To ensure efficient function of transformers, proper and timely purification of oil from gas and solids is essential. All the processes inside the transformer degrade the oil, which may lead to many malfunctions and problems with equipment.
