Transformer Insulating Oil

First it serves as electrical insulation to withstand the high voltages present inside the transformer.

Transformer insulating oil.

Second it functions as a heat transfer medium to dissipate heat generated within the transformer windings. Testing sequences and procedures are defined by various international standards many of them set by astm. Transformer oil also known as insulating oil is a special type of oil which has excellent electrical insulating properties and is stable at high temperatures. Transformer oil is used in oil filled electrical power transformers to insulate stop arcing and corona discharge and to dissipate the heat of the transformer i e.

1 excellent dielectric properties resulting in minimum power loss. This is because it tends to deteriorate over time. Electrical insulating oil 15. Low voltage strip can be bare with paper insulation between layers.

Transformer oil is basically an insulating oil. Now there are two main reasons for using this insulation oil in power transformers. It is a fluid or liquid substance that is common for transformer system and known as the most popular insulating material all over the world. It is used in oil filled transformers some types of high voltage capacitors fluorescent lamp ballasts and some types of high voltage switches and circuit breakers its functions are to insulate suppress corona discharge and arcing and to serve as a coolant.

Insulating oil in an electrical power transformer is commonly known as transformer oil. Act as a coolant. Insulating oils or transformer oils are mineral electrical insulating oils processed from fractional distillation and treatment of crude petroleum. Insulation in oil immersed transformers the most common insulation today for high voltage windings in transformer is an enamel coating on the wire with kraft paper used between layers.

Sasol electrical insulating oil 15 is a naphthenic oil specially refined to have high dielectric strength and good long term oxidation. English south africa safety datasheet. Transformer oil a type of insulating and cooling oil used in transformers and other electrical equipment needs to be tested periodically to ensure that it is still fit for purpose. Introduction of insulating oil.

Transformer oil is responsible for. Electrical transformers need an adequate insulation. English south africa description. This oil used to collect through the partial distillation of crude petroleum.

Transformer oil testing consists of measuring breakdown. It is normally obtained by fractional distillation and subsequent treatment of crude petroleum. Generally the oil we use for the electrical power transformer insulation and cooling purpose is called the transformer oil or insulating oil. An insulating oil must have the following properties.

2 high resistivity leading to better insulation values between windings. Thus the oil must maintain good electrical properties while. The insulating oil in a power transformer performs two major functions.
