Figure 27: A Two phase-to-phase connected VT
Where:
1) shows how to connect the secondary side of a phase-to-phase VT to the VT inputs on the IED
2) is the TRM where these three voltage inputs are located. It shall be noted that for these three
voltage inputs the following setting values shall be entered:
VTprim
=13.8 kV
VTsec
=120 V
Please note that inside the IED only ratio of these two parameters is used.
