In addition, the measurement the zero sequence voltage should reflect the real value on the primary side and not just the voltage the PAW.Page 195 Commissioning current injection 13.1 Impact the P-coil's design the results of current injection air-gap d higher lower Imin Imax moveable core spindle moveable core fixed core primary winding PAW MW Figure 132: Basic design continuously adjustable P-coil PAW Power auxiliary winding W Winding P-coil with PAW In this case, the P-coil functions transformer. The ratio between the secondary current injection and the primary measured current value should stay the same regardless the coil/plunger position. .
