 A transformer uses electromagnetic inductionas a means of transferring energy from circuit to circuit. This is generallyused when there is a need for a change in voltage. Transformers that have arating of 500 KVA or higher are called power transformers, and these areusually oil-filled to facilitate cooling and insulation. In fact, thesetransformers may contain gallons of oil,…

Maybe three are many kinds of Contaminants in transformer oil: Solid particles like rust scales, dust and fibres Generation of carbon particles due to ageing of switchgear Aging fluids produce absorbed gases, causing equipment failure and arc suppression in switchgear Sludge formation Increase in acidity level Oil absorbs moisture resulting in free and dissolved water…
