In this video, we review a four-wire, three-phase, 240 volt delta connected transformer secondary with a 208V "high leg" created by center tapping the B phase winding.
Do you know what the most common mistake is when calculating the high leg voltage magnitude from a four-wire delta transformer with a center-tapped phase winding?
It is making the mistake of NOT using complex numbers (only using magnitudes), or, forgetting to include the angles in your calculations.
