Insulation Monitoring Device,AIM-T300
Insulation Monitoring Device,AIM-T300
AIM-T300 insulation monitoring device is designed and developed by Acrel gathering the design experience of electric power meter industry for many years to monitor the insulation condition of low voltage IT distribution system (ungrounded system). The product adopts advanced micro controller technology, with high degree of integration, compact size and easy installation, and it integrates intelligence, digitalization and networking. The device, with many functions such as insulation fault warning, fault alarm, event recording and so on, can be used in the mines, glass factories, electric furnaces and test facilities, metallurgical plants, chemical plants, and exploded dangerous places, computer center, emergency power supply and other places to monitor the insulation status of IT system in real time. When insulation fault occurs, it will alarm and remind the staff to check the fault.The products conform to the requirements of enterprise standard Q/VDCL-26-2017 IT System Insulation Monitor.
