ecuador Acrel AIM-T500 Industrial Insulation monitoring instrument
Product Description
Overview
AIM-T500 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.

Features
1. Function of insulation resistance monitoring, warning and alarm for the monitored IT system.
2. Multiple fault indication function, such as relay alarm output and LED alarm output.
3. Advanced field bus communication technology, and it can communicate with the host computer management terminal and monitor the operation status of the IT system in real time.
4. Fault event recording function. It can record the time and type of failure to provide convenience for operators to analyze the operation status of the system and eliminate faults in time.
5. Applicable for insulation monitoring of AC, DC and AC / DC hybrid IT systems.
6. Self checking function. realize the fault self-inspection of instrument hardware circuit.
7. Broken line monitoring function. Monitor the connection condition of the PE/KE.
8. The free option of manual reset/automatic reset.
9. Wide range of measurement, Allowable leakage capacitance of the system is large.
