– Phase U-Sync (parameter hidden) The value determined during commissioning testing the polarity the current and voltage channels. The absolute value and especially the phase must the same both measurement inputs. This transformer factor integrated the HPCI's firmware. The conversion ratio knu for the value Uns_Coil then 120. However, the same zero sequence voltage measured both devices. Configuration voltage channel 2 Measurement channel Default allocation and settings U2 Uns_Coil Ex. Default value: 30° . Values increments 15° can entered.: 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.  Setting for current input: Setting Description Ici Current injected PAW - wired cabinet default current channel 1 Default allocation current channels Measurement channel Default allocation and settings I1 Ici Ex. 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.Page 240 Commissioning the HPCI We take care it. Because the current injected the PAW, the ratio 12000 V/500 for the current transformer factor (kni) can set there. The current Ici already measured the sec- ondary side the current injection controller.: coil nominal voltage/100 V Knu 120 – current measurement inputs Current transformer HPCI module The current through the power auxiliary winding measured directly the HPCI with a 200/1 current transformer
