: coil nominal voltage/500 power auxiliary winding (PAW)
Kni 24
In the example, the coil's nominal voltage kV, the transformer's nominal value 100 V
and the PAW's 500 V.

Ex.
Values increments 15° can entered.
The reason for this that the synchronization voltage Usync the REG-DP/ REG-DPA may
not have the same phase the synchronization voltage the current injection controller.
The conversion ratio knu for the value Uns_Coil then 120.

Current transformer HPCI module
The current through the power auxiliary winding measured directly the HPCI with a
200/1 current transformer.
However, the same zero sequence voltage measured both devices.Page 240 Commissioning the HPCI

.
Because the current injected the PAW, the ratio 12000 V/500 for the current
transformer factor (kni) can set there.
