Abstract
This paper introduces a way of detecting zero and low resistance insulators defects in a 500 kV substation and studies the applicability of infrared thermal image technology used in deterioration insulator test area.The voltage distribution of the insulator strings among various voltage levels are analyzed,the heat produced by the deterioration insulators under different resistance and location are calculated,the boundary of blind zone of detection and a new field test method are proposed.Practical tests show that the new method make the success rate of detection based on infrared thermal image technology improve remarkably in its applicable range.关键词
