A three phase star connected alternator develops an rms voltage of V1 per phase at the fundamental frequency. It also generates a third harmonic component whose rms value is V3 . What is the line voltage of the alternator?

Question

TuteeHUB · Accepted Answer

$\sqrt {(V_1^2 + V_3^2)}$

TuteeHUB · Answer

$\sqrt {3(V_1^2 + V_3^2)}$

TuteeHUB · Answer

$\dfrac{\sqrt {V_1^2 + V_3^2}}{\sqrt 3}$

TuteeHUB · Answer

$\sqrt {2(V_1^2 + V_3^2)}$
