With the development of industrial technology, leakage current brings a great threat to the safety of industrial production. In order to improve the continuity and reliability of power supply, ungrounded power supply system is adopted in many important production sites. AIM-T series industrial insulation monitoring device is mainly used in AC ungrounded system in industrial fields such as mine, glass plant, electric furnace and test equipment, metallurgical plant, chemical plant, explosion dangerous place, computer center and emergency power supply. It is used to real-time monitor the insulation conditicxi of the system to the ground When the grounding fault occurs in the system, it will alarm in time to remind the relevant person to troubleshoot.
