19. IED case and IED plug-in unit
For safety reasons, the IED cases for current measuring IEDs
are provided with automatically operating contacts for short-
circuiting the CT secondary circuits when a IED unit is
withdrawn from its case. The IED case is further provided with
a mechanical coding system preventing current measuring
IED units from being inserted into a IED case for a voltage
measuring IED unit and vice versa, i.e. the IED cases are
assigned to a certain type of IED plug-in unit.
