22. 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IED unit is withdrawn from its case.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.
23. Selection and
ordering data
The IED type and serial number label
identifies the protection IED. The label is
placed above the HMI on the upper part of
the plug-in-unit. An order number label is
placed on the side of the plug-in unit as well
as inside the case. The order number consists
of a string of codes generated from the IED's
hardware and software modules.
Use the ordering key information to generate
the order number when ordering complete
IEDs.
