Paraffin oil, like mineral oil, is a by-product from the petroleum distillation process paraffin based products are relatively non-reactive and have excellent oxidation stability paraffinic oils have relatively high wax content, high pour point, and typically a high viscosity index (vi. Transformer protection 1 when a fault develops slowly,it produces heat, thereby decomposing solid or liquid insulating material in the transformer • the decomposition of the insulating material produces inflammable gases • this produces arcing which in turn overheats the insulating oil and causes the tanks to rupture further. This report emphasizes methods for determining, minimizing, and uniformly distributing the stress for cable joints and hv bushings the analysis is intended to reduce the failures caused by high stressed, to provide maintenance cost reductions, and to improve service reliability.

Transformer oil is a mixture of paraffinic, naphthenic and aromatic hydrocarbons is prone to oxidation many polar compounds such as acids, aldehydes, ketones, peroxides and alcohols are formed due to the.
Oil based cb: the insulating oil (eg, transformer oil) is used as an arc quenching medium the contacts are opened under oil and an arc is struck between them the heat of the arc evaporates the surrounding oil & dissociates it into a substantial volume of gaseous hydrogen gas @ high pressure. For small units of transformer, coil wire can be round and laminated with cotton, enamel, paper, varnish etc whereas for larger units coil wire taken is usually square or rectangular ribbon insulated with oil impregnated paper, for higher temperature applications glass or plastic is used for insulation. The proposal offers a simple, a quick, and an accurate of diagnosis through machine-human interface, while which was quickly, simply, and accurately proved on october 25th, 2012 nan cou e/s #4 atr's insulating oil of diagnosis. Transformer oil is used in the oil filled transformer and in some other system such as high voltage capacitors, fluorescent lamp ballasts, circuit breaker etc basic requirement of transformer oil is that it should be stable at high temperatures with excellent electrical insulating properties and suitable cooling property.
In view of difficult for the power transformer insulating oil level in the real-time online monitoring of the artificial using fiber bragg grating as the insulating oil level sensor tms320f2812 digital signal processor was used as the processing and control core. For example, transformer oil, hydrogen and helium are used for both insulation and cooling purposes for such materials, good thermal conductivity is desirable the insulators should also have small thermal expansion to prevent mechanical damage. For illustration, transformer oil, hydrogen and helium are used for both insulation and cooling purposes for such materials, good thermal conductivity is desirable the insulators must also have small thermal expansion to prevent mechanical damage.
