XFMR Calculation. What voltage is expected across points A and B? Across points B and C

[From: ] [author: ] [Date: 11-12-15] [Hit: ]
X2 and X3 and the neutral would be connected to X0.In this case, you would measure 208 volts across X1 and X2 (points A and B) and 120 volts across X2 and X0 (points B and C).Voltage between phase and neutral = 208 / sqrt(3).......
H side has 600v D and X side has 208v Y.
A and B are X1 and X2 connected and
B and C are X2 and X0 connected.

Im not sure how to do this problem so if possible please explain formula and calcultion with example. Thank you sooooo much.

It is impossible to answer your question without seeing a connection diagram of the transformer. Typically, the phase conductors on the low voltage side would be connected to X1, X2 and X3 and the neutral would be connected to X0. In this case, you would measure 208 volts across X1 and X2 (points A and B) and 120 volts across X2 and X0 (points B and C). Voltage between phase and neutral = 208 / sqrt(3).
