So I'm doing a delta wye transformer in simulink and phase shift between these two signals should be 30 degrees, but how to show that, or calculate it? And how to find angle of each signal?
Use the frequency and period of the wave.
Then the equation is:
Phase shift = 360 * time / wave period
Phase shift is in degrees and time is the time difference.
And you don’t want to find the angle of each signal rather you want to find the phase angle difference between the two sine waves.
