Abstract: In order to evaluate the quality level of resistive current tester products for zinc oxide arrester scientifically and effectively,and distinguish between strong and weak suppliers,a comprehensive quality evaluation method of tester based on Analytic Hierarchy Process（AHP）-entropy weight method is proposed in this paper. By means of mathematical statistical analysis,quantitative assignment and weighted adjustment of test results,the quality evaluation index is extracted from two dimensions of technicality and economy. Finally,through the subjective and objective combination of weights,combined with the objective data,the comprehensive evaluation index of each product is obtained and comprehensive quality ranking of different manufacturers’ products is achieved.The example results show that this method can better distinguish the quality levels of testers from different manufacturers,and highlights the quality shortcomings or weak links of some products such as large dispersion,poor anti-interference performance,and poor maintenance economy of measurement results,which can provide reference for quality improvement,bidding and procurement and network access testing of related products.
