The oil is very important to the reliability of the transformer, particularly its long-term reliability. So we were keen to use a very good oil. EDF Energy is part of the wider EDF group which is based in France, so they have a very good research and development department. They gave us some confidence that it was a good oil and that it was suitable for use in our transformers.

The dielectric constant - also called the relative permittivity indicates how easily a material can become polarized by imposition of an electric field on an insulator. Relative permittivity is the ratio of "the permittivity of a substance to the permittivity of space or vacuum".. Relative permittivity can be expressed as ε r = ε / ε 0 (1) ...

Transformer oil is a mineral based oil that is commonly used in transformers for its chemical properties and dielectric strength. This oil in your transformer acts as an insulator and a cooling agent. Over time, the oil will degrade resulting in the potential for faults and costly repairs. With a proper preventative maintenance program, you can avoid any costly down time and expensive repairs.

Hence, considering above mentioned properties commonly used dielectric fluids in EDM are hydrocarbon oil, e.g., transformer oil, paraffin oil, kerosene; lubricating oil, gas, air and also deionized water. Dielectrics can be classified into the following three groups as follows: (i) Hydrocarbon oil based dielectrics: This type of dielectrics of EDM is normally used in sinking EDM.

Transformer Oil is basically an Insulating Oil. Insulating Oils or Transformer Oils are mineral electrical insulating oils processed from fractional distillation and treatment of crude petroleum. An Insulating Oil must have the following properties: 1) Excellent dielectric properties resulting in minimum power loss. 2) High resistivity leading to better insulation values between windings. 3 ...

The oil test in which spark occurs and the testing set trips is known as transformer oil dielectric strength test. This test is performed in the oil testing set. Suitable oil testing sets, stationary as well as portable, are available for testing the oil under the specified conditions. A sample of the oil is drawn from the transformer and tested in the oil testing set. A lower than

A car requires oil for lubrication while a transformer requires oil for insulation and cooling. Just as a car requires regular checks of both oil quality and oil level, a transformer requires the same proactive treatment. Oil in each instance degrades over time resulting in the potential for failure or costly repair bills. Regular maintenance and upgrading of the oil will add years to the life ...
