Example application: Ungrounded power system insulation monitoring and the alarm output is sent to a supervisor

You can use an IMD to monitor an ungrounded power system and send the alarm to a supervisor.

An ungrounded power system is a system involving the use of a transformer whose neutral is not connected to ground.

The insulation is monitored by an IMD whose insulation alarm and preventive insulation alarm outputs are connected to an available input on a networked device (For example: PLC). This device is connected to a supervisor via a communication network.

NOTE: In this scenario, only the insulation alarm and preventive insulation alarm information are available to the supervisor.
