Bahrain Acrel AIM-T500L Industrial Insulation monitoring instrument
Product Description
Overview
With the development of industrial science and technology, residual current poses a great threat to industrial production safety. In order to improve the continuity and reliability of power supply, many important production sites adopt IT distribution system (ungrounded system).
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.
The products conform to the requirements of enterprise standard Q/VDCL-26-2017 IT System Insulation Monitor.
