The input power and output power are continuously changing, so does the operating efficiency of transformer due to the difference between the power supply object and load nature. For this reason, designer should firstly understand the power supply object and operation characteristic of load when selecting the transformer and then correctly select the transformer capacity comprehensively considering other conditions based on acquisition of optimal operating efficiency of transformer. The calculating method proposed in this paper for operating efficiency and optimal operating efficiency of transformer has practical value for the economic and energy-saving operation of transformer.
