Abstract :
While on-line insulation monitoring of HV apparatus is giving more and more attention, how to analyze the data and increase the diagnosis veracity is becoming a new problem, for the online monitored data often vary. In this paper, a new on-line insulation monitoring system for HV instrument transformers, power transformers, bushings and MOA is presented. Then the influence of some factors on the monitored results is analyzed through experiments. The influencing factors include potential transformers, adjacent phase apparatuses and ambient factors. Based on the experimental results and analyses, an online insulation diagnosis expert system for HV apparatus is developed
