The status evaluation of distribution transformers is a systematic process, and selecting appropriate methods can quickly and accurately evaluate its operating status. In this paper, the characteristics of the transformer are integrated and a method for evaluating the state of the transformer before delivery based on the analytic hierarchy process (AHP) is proposed. This method calculates the weight through the analytic hierarchy process, collects the field state quantity data, and adds the weighted sum of the state scores at each level, and finally determines the overall health state of the transformer. The calculation result of this method is accurate and the process is clear. After substituting actual data, the calculation results show that the method can accurately assess the health status of the transformer. The proposed method has broad application prospects in the evaluation of the transformer status.
