Figure 11: Example how to set CT_WyePoint parameters in the IED
For busbar protection, it is possible to set the CT_WyePoint parameters in two ways.
The first solution will be to use busbar as a reference object. In that case for all CT
inputs marked with 1 in Figure
11, set CT_WyePoint =
ToObject, and for all CT inputs
marked with 2 in Figure
11, set CT_WyePoint
= FromObject.
The second solution will be to use all connected bays as reference objects. In that case
for all CT inputs marked with 1 in Figure
11, set CT_WyePoint
= FromObject, and for
all CT inputs marked with 2 in Figure
11, set CT_W
yePoint
= ToObject.
