I am experiencing difficulties with a question:
A balanced three-phase load shown in the diagram is connected across a 380V, 50 Hz three-phase supply, ABC phase sequence. The voltage VAB is taken as reference.
Part of the question I am trying to answer includes converting the WYE circuit to a Delta circuit as I have done:
Now, my main question is how do I work out the phase angle of each component?
My textbook does not have notes on how to determine the phase angle. All they say is VBC is generally used as the reference phasor. But in this case, VAB is used as the reference phasor and I don't know how to determine the angles for the phasor diagram. I thought of rotating the reference diagram of VBC so that VAB = 0, VAC = 120 and VBC = 240. Would I be correct on this approach? Please advise
