Question:
A three-phase transformer in a large building steps down the primary voltage of 13.8 kV (line-to-line) to a secondary voltage of 208 V (line-to-line). The transformer rating is 5000 kVA. Specify the line and phase voltages and currents of the transformer’s primary and secondary windings for the following connections:
(a) Low-voltage windings Δ, high-voltage windings Y
(b) Low-voltage windings Y, high-voltage windings Δ
(c) Low-voltage windings Y, high-voltage windings Y
(d) Low-voltage windings Δ, high-voltage windings Δ
