Hi,
I'm studying transformer and am a bit confused. Say for vector group: Dy11, I guess it's the line voltage of LV leads the Line voltage of HV by 30 degrees. Book says phase angle. The phase angle is line voltage right,
since the phase voltage of HV and LV will always be in phase with each other.
I googled up for it, but everywhere it says phase angle. Just wanted to clarify whether phase angle is angle between line voltage of lv and hv side.
Thanks in advance for the answers.
