# Balanced delta source to Wye source by considering magnitude only is ok?

I read and derived formulas for balanced delta source to Wye source; it is given by Vy = Vd / sqrt(3)<30 but in some places I see people only dividing by sqrt(3) for conversions are keeping angle 0, is it the correct way for conversion ?

$$\ V_Y = \frac {1}{\sqrt 3} V_{\Delta} \$$ is all you need.
