Selection method of distribution transformer capacity

In this paper,factors need to be considered in choosing transformer capacity and several methods in selecting transformer capacity are discussed.The optimum load factor,minimum power loss,energy saving load factor and economic load factor of transformer are determined by technical analysis and calculation.A proper running type and transformer capacity should be selected in view of user load and the first time installation fee,so as to make transformer operate economically and decrease active power loss.Ther...
