Abstract—The scope of this paper is to focus on cost effective design, reliable and environment friendly distribution transformer. The huge number of distribution transformer is required for electrification of any country so cost effective design is required. Oil immersed distribution transformer can be built with very low losses compared to dry- type transformers. Planning long tem responsibility to global environment this should be emphasized together with low fire risk, non-toxic biodegradable or recyclable materials. Envirotemp FR3 is a natural ester made from edible seed oils and is 99% biodegradable [1]. Use of the FR3 oil for transformer cooling, makes transformer reliable and environmental-friendly.
