Abstract

Distribution Transformers are one of the imperative equipment used in the power system. The insulation design of the transformer plays an important role, because it is continuously energized in a day. Due to the electro mechanical stresses, the operating temperature of the distribution transformer will be increased and it is also maintained within the limit using liquid dielectrics. Traditional mineral oil is the one which is used as the liquid dielectric in the Distribution Transformers. Due to its limited fire resistant characteristics, lesser biodegradability characteristics and also due to the lack of fossil fuels, the alternate liquid dielectrics are very important in an insulation design of the Distribution Transformers. This research work has been proposed on non edible Pongamia Pinnata Oil as an alternate liquid dielectric which can be used in Distribution Transformers. This paper Pongamia Pinnata Oil (PPO) Electrical, Physical and chemical properties has been estimated according to Indian standard to study the feasibility of alternating liquid dielectrics. The experiments results are compared with traditionally used mineral oil. It has been found that PPO has better Electrical, physicochemical characteristics than that of mineral oil.
