Example application: Locating the insulating alarm with IMD
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. The device has a single relay output to control a light or a buzzer.
