Transformer oil is a petroleum product that is used as a heat transfer medium in the transformer\u2019s core and windings as well as an insulating fluid preventing short circuits and arching inside the transformer.<\/p>\n

One of the important parameters of transformer oil is viscosity. \u00a0Higher viscosity reduces the oil\u2019s heat dissipation efficiency. \u00a0The oil you are using, or want to use, should be checked for compliance with the required specifications before using the oil in a transformer.<\/p>\n

Dielectric properties of the oil are defined by several parameters: dielectric strength, acidity, dissipation factor, particulate matter content, the content of water and water soluble acids, alkali, and flashpoint. \u00a0The established parameters must not fall below the required specifications. \u00a0Critical limits are usually given in regulatory documentation and will reflect national and international industrial standards.<\/p>\n

Why does the transformer oil degerade over time?<\/b><\/h2>\n

During the operation of a transformer, several adverse factors influence the transformer oil that cause contamination, ingress of moisture and oxidation. The result is the progressive degradation of the dielectric fluid that includes both the chemical and physical properties the oil. \u00a0The adverse elements affecting the oil are oxygen, high temperature and metal salts that become the catalysts of the detrimental oxidation process.<\/p>\n

Degraded transformer oil cannot function correctly; it must be either replaced or regenerated using specialized equipment.<\/p>\n

Replace or Restore?<\/b><\/h2>\n

Simple replacement of old oil with new oil does not completely solve the transformer\u2019s existing problems entirely. \u00a0When used oil is drained from the transformer, contamination will remain in the tank, core, winding, and solid insultaion. \u00a0The remaining contamination will accelrate the degradeation of the new oil. \u00a0Additionally, the remaining contamination will continue to harm the solid insulation.<\/p>\n

Once the oil has been drained from the transformer, the old oil must be disposed of properly. \u00a0It cannot be simply dumped into the ground or \u00a0water.<\/p>\n

Oil products are a hazardous waste pollutant. Used oil will disrupt and harm the lives of animals, fish and birds and cause serious diseases in humans that include cancers. \u00a0Properly disposing of used oil is mandatory, and expensive.<\/p>\n

A less expensive alternative is the restoration of old transformer oil. \u00a0Restoration will extend the service life of the oil without the need to \u00a0replace the oil and is free from the many drawbacks of removing and replacing the used oil. \u00a0Some methods of restoration include drying, purification and regeneration.<\/p>\n

Transformer oil can be purified by removing particulate matter and moisture through the use of centrifuges and filters. \u00a0The oil can be dried by sorbent materials with high water adsorption and retention such as zeolites and silica gels.<\/p>\n

Essentially, regeneration involves the completerestoration of oxidized oil by removal of the aging products.<\/p>\n
