Abstract: As the Optical Current Transducer (OCT) is gradually and widely used in power systems, how to scientifically and accurately ｓｅｌｅｃｔ OCT products with superior performance, high quality and low price plays an important prerequisite role in reducing maintenance costs, realizing the stable operation of the power sys-tem and improving economic benefits. Based on the characteristics of Optical Current Transducer, this thesis selects four index factors of functional stability, maintainability, price and electronic component quality, si-multaneously using the Analytic Hierarchy Process(AHP) to analyze and evaluate each index factor. Finally, in the overall sorting screening stage, according to the principle of maximum membership degree, the element with the largest total sorting weight value is selected to be the optimal product decision plan.
