If I have a fundamental waveform of 110V 50Hz with a 3rd harmonic waveform of 15V 150Hz how do I find the sum of the instantaneous voltages.
For instance if I want to find the sum of the instantaneous voltages at 50deg:
I have
e = Vpeak x sin 50deg
= 110 x 0.766
= 84.26V for the Fundamental waveform
For the 3rd harmonic waveform do I just do the following & then add the two together?
e = Vpeak x sin 150deg
= 15 x 0.5
= 7.5V
Somehow this doesn't seem correct?
Cheers
