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secondary circuits when a IED unit is withdrawn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.
