Transformer Oil Purification methods and Standard
Small samples are taken to the test and kept air tight. Gases are extracted from the oil with a vacuum pump and the gases are identified using gas chromatography. Hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, methane, ethylene, ethane and acetylene are the most common gases found in the oil.

The Functions of Transformer Oil And Oil Restoration Methods
Transformer oil is a petroleum product that is used as a heat transfer medium in the transformer’s core and windings as well as an insulating fluid preventing short circuits and arching inside the transformer. One of the important parameters of transformer oil is viscosity. Higher viscosity reduces the oil’s heat dissipation efficiency. The oil
