Insulation Monitoring Devices
Insulation monitoring devices are normally used in IT mains with insulated
neutral point. The aim is to have a monitor triggered in the case of ground
fault - i.e. in the case of error - without having to switch off the electrical
equipment.
When the monitor signals an error, the ground fault is detected and
removed without operation being switched off. Switch-off only takes place
if a second ground fault occurs before the first one has been removed.
As insulation monitoring devices are also measuring the ground current at
the mains input of the building, too high leakage current can cause
accidental false triggering.
There are the same notes on application applying as mentioned in the
previous section "Use of Residual-Current-Operated Circuit-Breakers
(RCCB, RCD) as Additional Fusing".
