Power industry on the introduction of energy-efficient distribution transformers industry standard technical and economic evaluation guidelines, to promote the replacement of old transformers, energy efficiency decreases, played a positive role.

On the technical performance of energy-saving transformer has a very prominent advantages, also vigorously promote the popularization of China’s current stage, but it is accepted by the market situation is not optimistic.

Electrical power transformer is a key power transmission equipment, transformer losses account for 30% to 40% in power consumption, whereas the loss of all transformer itself accounts for more than 3% of the country’s electricity. Therefore, the state has been concentrating on saving energy in the transformer, and vigorously promote energy conservation.

The State Council issued the "energy saving Twelfth Five Year Plan" detailed draft, clear energy saving during the second five specific objectives and investment planning, reduce power requirements during the second five transformer losses, which load loss reduced by 10% to 13 % load loss reduced by 17% to 19%.

Ministry of Finance, the National Development and Reform Commission, Ministry of Industry and Information Technology to Finance Building [2012] No. 854 issued "Energy Efficient Appliances energy efficient distribution transformers promote the implementation details." The "Rules" of the scope and conditions of the promotional products, promotional business conditions, the promotion period, promotion allowances, promotion eligible to apply for funding and disbursement of subsidies, penalties seven parts, promotional products to apply pressure level of 10 kV three-phase, No excitation voltage, energy efficiency rating 2 and above, the rated capacity of 30 kVA to 1600 kVA oil-immersed and rated capacity 30 kVA to 2500 kVA dry-type transformers with Shen.

In fact, the transformer energy efficiency standards is one of the key power standardization work. In 2005, the power industry on the introduction of energy-efficient distribution transformers industry standard technical and economic evaluation guidelines, to promote the replacement of old transformers, energy efficiency decreases, played a positive role.
