Application manual
It shall be noted that depending on national standard and utility practices the rated
secondary voltage of a VT has typically one of the following values:
•
100 V
•
110 V
•
115 V
•
120 V
•
230 V
The IED fully supports all of these values and most of them will be shown in the following
examples.
Examples on how to connect a three phase-to-ground connected VT to the
IED
Figure

gives an example on how to connect the three phase-to-ground connected VT
to the IED. It as well gives 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.
