Abstract In order to improve the effectiveness, accuracy and efficiency of infrared detection of substation insulators. In this paper, the equivalent circuit simulation model of insulator string is established by Matlab/Simulink dynamic system modeling and simulation software, and the relationship among potential distribution, insulation resistance, heating power and temperature rise of insulator string is deeply studied. The main points and discriminant methods of infrared detection of insulators are obtained, which provide theoretical basis and technical reference for the infrared detection technology of substation insulators.
