2 Functional characteristics
2.1 AIM-T500L insulation monitor
■Monitor resistance of IT system real time, warning or alarm when the resistance exceeds the limit;
■Relay alarm output, LED alarm output and other fault indication modes;
■SOE function, convenient for staff to check and analyze the failure type and occurrence time, and
judge the operation status of the system;
■Self-check function, which can realize fault self-check of instrument hardware circuit;
■ Disconnect monitoring, real-time monitoring of PE/KE function grounding wire connection status;
■ RS485 interface, standard Modbus-RTU protocol;
■ CAN interface, custom protocol, used to interact with signal generator and fault locator;
■ Support manual/automatic reset modes;
■ Wide range of applications, suitable for AC, DC and AC-DC hybrid IT systems.
2.2 ASG200 test signal generator
■ Generate positioning signals and inject them into the ungrounded system;
■Indicate the phase line where the fault is;
■Manual startup positioning is supported;
■CAN bus technology is adopted to facilitate data interaction with other devices in the system.
2.3 AIL200-12 insulation fault locator
■ Locate and indicate the loop where the fault is;
■ A single AIL200-12 can locate up to 12 loops;
■ Each IT system can be connected to a maximum of 90 locators, with a total of 1080 loops;
■CAN bus technology is adopted to facilitate data interaction with other devices in the system.
2.4 AKH-0.66L series current transformer
■Rated current ratio 5A:5mA , select model according to the rated current of the loop;
■Coordinate with AIL200-12 insulation fault locator to achieve fault location.
