Transformer mineral oil (TMO) is a clear liquid with an odour of petroleum. 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. Density of Transformer Oil at 29.5oC is 0.89g/cm3. Compare the typical characteristics and performance of mineral oil, FR3 ® natural ester fluid, synthetic ester fluid, and silicone transformer oil.. For a more precise estimate tailored to your needs, contact us. Transformer Dielectric Fluid Comparison. Transformer Oil Description Castrol Insulating Oil is a pure mineral hydrocarbon oil, specially refined and blended from selected crudes. Mineral oil varies in specific gravity from 0.818 to about 0.920, depending on how refined it is. "State system for ensuring the uniformity of measurements for the density of oil. Most power transformers are filled with mineral oil refined to achieve the desired electrical and chemical properties. The choice of a new mineral oil is guided by the IEC 60296 standard. Yes. 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. This increases the possibilities for a longer transformer life with less maintenance. An American leading oil refinery that manufacture and sells transformer mineral oil. Crude oil or petroleum has always been the primary source of TMO. 2.2 Silicone fluid Silicone based liquids have been used by transformer manufacturers since the end of 1970’s7, as an alternative to the PCB based liquids, mainly for fire safety applications. Oil is used to cool the transformer, because it also provides part of the electrical insulationbetween internal live parts, transformer oil must remain stable at high temperatures for an extended period. Higher viscosity may mean better dielectric strength, but may reduce the ability of the oil to transfer heat and cool the transformer. It has a density of around 0.8–0.87 g/cm 3. Another instance when the sampling point of a transformer can change is after the retrofill of insulating fluid, such as Askarel to Silicone. The basic chemical structures of all the oil are more or less the same. h�bbd``b`�$���0 �n $Xw � @��Dl�Ab�AHI>H�2���������b``�5���� q0 Transformer oil or insulating oil is an oil that is stable at high temperatures and has excellent electrical insulating properties.
