During normal operation, the neutral voltage in a three-phase system is close to zero, regardless of whether the neutral point is tied to the earth. .
The positive sequence reactance of a synchronous generator is defined by the generator inductance. The use of the inductance value to calculate the positive sequence impedance is. .
a) Circuit Configuration VA VCA G VAB VA = VG VC VBC VB VC VBC VB b) Vector Diagram Figure 2. Single-Line-to-Ground Fault on a System with a Grounded Transformer. .
Many grid tied PV inverters have an internal transformer. If the transformer is wye-delta configured with the wye on the grid side, the neutral terminal can be used for effective grounding as shown in Figure 3 a). In most of the cases,. [pdf]
