Typical connection of Industrial Electrical Insulation Safety Meters


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 location system 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.




Function description of Industrial Electrical Insulation Safety Meters

AIM-T500L insulation monitor

1) Monitor the insulation resistance of IT system in real time, warning or alarm when the resistance exceeds the limit;

2) Relay alarm output, LED alarm output and other fault indication modes;

3) SOE function, convenient for staff to check and analyze the failure type and occurrence time, and judge the operation status of the system;

4) Self-check function, which can realize fault self-check of instrument hardware circuit;

5) Disconnect monitoring, real-time monitoring of PE/KE function grounding wire connection status;

6) RS485 interface, standard Modbus-RTU protocol;

7) CAN interface, custom protocol, used to interact with signal generator and fault locator;

8) Support manual/automatic reset modes;

9) Wide range of applications, suitable for AC, DC and AC-DC hybrid IT systems.


ASG200 test signal generator

1) Generate positioning signals and inject them into the ungrounded system;

2) Indicate the phase line where the fault is;

3) Manual startup positioning is supported;

4) CAN bus technology is adopted to facilitate data interaction with other devices in the system.


AIL200-12 insulation fault locator

1) Locate and indicate the loop where the fault is;

2) A single AIL200-12 can locate up to 12 loops;

3) Each IT system can be connected to a maximum of 90 locators, with a total of 1080 loops;

4) CAN bus technology is adopted to facilitate data interaction with other devices in the system.


AKH-0.66L series current transformer

1) Rated current ratio 5A:5mA, ratio 1000:1, select the appropriate aperture according to the rated current of the loop;

2) Coordinate with AIL200-12 insulation fault locator to achieve fault location.
