AIM-T500L Industrial Insulation Monitor
General
AIM-T500L series industrial insulation monitoring and fault is specially developed by Acrel for IT distribution system in industrial occasions such as mine, glass factory, electric furnace and test equipment, ship, metallurgical plant, chemical plant, explosion hazard site, computer center and emergency power supply. The system has rich functions, including insulation resistance monitoring, insulation fault warning, insulation fault alarm, event recording, parameter setting, communication networking, etc. When the system has grounding fault, it can give a timely alarm and accurately locate the specific circuit of the fault to remind staff to check the fault in time.
