Abstract: Mineral transformer liquids are used as dielectric liquids from a long time and preferred by power utilities worldwide because of its good physical, mechanical & dielectric properties, ease of accessibility and low cost. But due to environmental constraints, non-biodegradability nature and less fire resistive nature of it proves to be destructive for surroundings as well as to the manpower dealing with it. Number of alternatives were suggested by researchers have been implemented in distribution and power transformers. In current research work, biodegradable modified synthetic ester fluid is proposed as an alternative to mineral transformer oil because of its electrochemical properties such as; dielectric strength, resistivity, flash and fire point, acidity and water content which have been practically analyzed in laboratory. Analysis reveals that ester oil has astounded fire resistive properties and moisture tolerant liquid over mineral oil.
