On the basis of in-depth analysis on data acquisition condition in all kinds of sensor device of distribution network equipment

comprehensively considering the influence factors of energy efficiency of the equipment

the index system of energy efficiency evaluation of distribution network equipment is established.According to each index has different energy efficiency influence degree on the distribution network equipment in the energy saving potential

cost and difficulty aspects

hierarchical structure model is established

and the analytic hierarchy process（ AHP） is used to calculate index weights. According to the characteristics of the quantitative indicators

which are easy to quantify

the benchmarking function is established

the energy efficiency index calculation of quantitative indicators is completed. Thus

energy efficiency evaluation for distribution network equipment is achieved. And an actual distribution transformer example is taken to verify the practicability and effectiveness of the proposed method.
