ABB REL650 - Examples on How to Connect a Three Phase-To-Ground Connected VT to the IED

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.
4.2.4.3 Examples on how to connect a three phase-to-ground connected VT to the
IED
Figure
43 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.
For correct terminal designations, see the connection diagrams valid for
the delivered IED.
