Abstract：It was introduced that a typical case of discovering arrester detect which was used by infrared thermal imaging and resistance current. The detection results were confirmed by de-energized tests and disassemble check. The reasons of the defects are that the valve plates at the middle and lower parts of the arrester are affected with damp and the drying of the insulating wood blocks of the base is not complete, resulting in corrosion of the base and damage to the insulation of the arrester. Resistance current with infrared thermal imaging can discover the inner defect of arrester effectively. Finally, suggestions on manufacturing, acceptance and live detections are put forward.
