A New Evaluation System Method for Small Current Grounding Line Selection Device

Abstract: The evaluation of small current grounding line selection device plays an important guiding part in fault diagnosis and device promotion. But the current methods focus on the evaluation of individual indicator and can not form systematic evaluation of the programs.This paper firstly makes use of AHP method to evaluate small current grounding line selection device, and establishes the evaluation system of small current grounding line selection device. During the weight solution process, this paper uses three scale method to determine the comprehensive weight of individual indicator, and achieves a combination of expertise and quantitative, qualitative assessment of the results. The practical case analysis of small current grounding line selection device proves the validity and practicability of this method, which is of great theoretical and practical significance.
