With the aim to relieve the problem ofenergy shortage, the State Development and Reform Commission places the great emphasis ofenergy-saving work on improving energy efficiency of industrial energy-consuming products inenergy-saving work. The General Administration of Quality Supervision, Inspection and Quarantine ofthe People's Republic of China (AQSIQ) has issued and implemented two energy efficiency standardsfor three-phase induction motors and displacement air compressor, and will soon issue another twoenergy efficiency standards for clean- water centrifugal pumps and ventilation fans. The transformeris a kind of electric equipment widely used in many industries in national economy, with featuresof great amount of use, long period of operation and tremendous potential of energy-saving. So, itis necessary to develop the standard of energy efficiency for distribution transformers.展开更多
