The relationship between line and phase voltages and currents in star connected networks is given by
1
\({V_{ph}} = {V_L},{I_{ph}} = \frac{{{I_L}}}{{\sqrt 3 }}\)
2
\({V_{ph}} = \frac{{{V_L}}}{{\sqrt 3 }},{I_{ph}} = \frac{{{I_L}}}{{\sqrt 3 }}\)
3
Vph = VL, Iph = IL
4
\({V_{ph}} = \frac{{{V_L}}}{{\sqrt 3 }},{I_{ph}} = {I_L}\)
