Acrel AIM-T500 Industrial Insulation Monitoring Device
Acrel AIM-T500 Industrial Insulation Monitoring Device
General
Acrel Industrial insulation monitoring device is mainly used to monitor the insulation status of the IT system (ungrounded system) to the ground, and timely alarm when the system has insulation fault to remind the electrical maintenance personnel to check the fault. It is suitable for AC and DC ungrounded systems in industrial fields such as electrolytic aluminum, mines, glass factories, electric furnaces and test equipment, metallurgical plants, chemical plants, explosion-hazardous places, computer centers and emergency power supplies.
