Product Description

 

 

Overview

     

 

        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.

Features

 

 

1. Function of monitoring, fault warning and alarm the ground insulation resistance for IT system;

 

2. Multiple fault indication function, such as relay alarm output, LED alarm indication and so on.

 

3. Advanced field bus communication technology, communicate with the external alarm and display device or the upper 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 query and 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 between the L1/L2 and the IT system and the connection condition of the PE/KE function grounding wire.
