star phase voltages

3-phase power star connection. Measure the phase voltages and line voltages (Vp & VL). In this circuit, was cannot get the true result of the line voltage, the line voltage should be around 26V.(Regard the phase voltage is 15V) In star network, VL(line voltages) = √3VP(phase voltages) When a star-connected system is balanced, then the neutral conductor is unnecessary and is often omitted.
