In the given figure, the potential difference between the poles is 230V but in case of star connected network in the household, the potential difference between two phases is 400V. The potential difference between line and phase is 230. So the star connection should be like the following.
a) The line that starts from the common point is called neutral line. The potential of this line is zero.
b) The phase line, neutral line, and earth line are used in the household electrical winding. The voltage difference between a phase line and the neutral line is 230V.
c)The voltage between two phase lines is 400V.
