AB Through analysing the infrared temperature measurement data obtained from composite insulators for overhead lines in actual operation state and atmospheric environment, detection requirements of infrared accurate temperature-measuring technology of composite insulators for overhead lines were discussed, such as the detector, detection environment, and position. According to the local detection, two kinds of insulators' local heating, caused by insulation deterioration and damp contamination on the surface, were researched. A judgment method was proposed, and overheat of the electric equipment, which was caused by voltage effect, should be judged from both the contrast of similar equipment and the thermal image characteristic. This method can greatly reduce the insulators overheat error rate, improve the detection efficiency of composite insulators, and enhance the accuracy of composite insulators' insulation defects judgment.
