Example application: Locating the insulating alarm with IMD, where device and IMD are connected to communication network

You can use the device to locate the insulating alarm of an ungrounded power system with IMD connected to communication network.

IMD is powered by the ungrounded power system that it monitors. IMD is connected to neutral (or to one phase) and ground. The device is connected to the toroids. Toroids are connected to the channels of the system.

IMD monitors the insulation of the system. The device locates the channel where the insulation fault occurs. IMD and the device are connected to a supervisor via Modbus communication. This application can support the following actions from the supervisor level:

  • Display:

    • Product status

    • All the channels insulation alarm (active and acknowledged)
