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

However, the same zero sequence voltage measured both devices.
– Phase U-Sync
The value determined during commissioning testing the polarity the current and
voltage channels.
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. Because the phase the only thing that is
important U-Sync, knu can used here. The current Ici already measured the sec-
ondary side the current injection controller
