* real-time monitoring and fault alarming of the ground insulation resistance,
* transformer load current and transformer winding temperature of the monitored IT system,
* be used with insulation fault locator, remotely starting fault-locating and displaying locating results when there are
insulation faults,
* real-time monitor the line disconnection fault, temperature sensor disconnection fault and the functional grounding line
disconnection fault of the monitored system, and give the alarm indication within 2S after the fault occurs,
* relay alarm output, LED alarm indication and other faults indication functions,
* used for centralized alarm and display instrument, test signal generator, insulation fault locator and upper computer management
software communications, and can monitor the operation status of IT system in real time.
* Events logging function, which can record alarm occurrence time and fault type and is convenient for operation personnel to
analyze the operation conditions of system and promptly eliminate the faults.
