Consider the three-phase transformer shown in Fig. 13.136. The primary is fed by a three-phase source with line voltage of 2.4 kV rms, while the secondary supplies a three phase 120-kW balanced load at pf of 0.8. Determine:
(a) The type of transformer connections,
(b) The values of ILS and Ips,
(c) The values of ILP and IPP,
(d) The kVA rating of each phase of the transformer.
