Environment Friendly Distribution Transformer is offered with on load tap changer for voltage variations and for long distance ruler power distribution lines, autotransformers with automatic tap changing equipments are inserted as voltage regulations, so that user at the far end of the line receive the same average voltage as those closer to the source. The Transformer has low flux density to withstand severe over excitation and has use of magnetic shields to control strong flux. The Transformer has good shield circuit strength and is environment friendly type in nature. The Environment Friendly Distribution Transformer has large overload capability depending on the ambient temperature, large over voltage capability on generator side to withstand the over voltage coming for load rejections.
