Out of Phase Voltages

07/18/2010 8:39 AM

geometric sum of three equal sinusoidal voltages that are out of phase..how can it be solved out?

By knowing the phase angle of the three voltages, converting the voltages to the real and imaginary components and adding. Now finish your homework.

You didn't specify phase angles.

Crayons and a ruler can be used to find resulting phasor R=A+B+C graphically...

Hint: the resultant vector sum is the voltage between neutral and earth....

The previous post showed you how to do it. With a vector diagram. You should thank them.

If all three are not only equal in amplitude, but 120 degrees apart, they will sum to zero.
