The IED fully supports all of these values and most of them will be shown in the following
examples.
4.2.4.3 Examples on how to connect a three phase-to-ground connected VT to the
IED
Figure
20 gives an example on how to connect the three phase-to-ground connected VT
to the IED. It gives an overview of required actions by the user in order to make this
measurement available to the built-in protection and control functions within the IED.
For correct terminal designations, see the connection diagrams valid for
the delivered IED.
