(usually 230 AC)
Uns_Coil Zero sequence voltage directly the P-coil (usually 100 UNE
Uod_Grid Zero sequence voltage measured directly the busbar using the delta wind-
ing (usually 100 V)
Uci Voltage measured directly where the current injected.
The transformer factor must defined for each input.Page 204 Commissioning current injection
