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, rmS. If the transformer feeds a 120-kVA load, find:

(b) the values of ILS and IPS,

(c) the vales of ILP andIPP

(d) the KVA rating of each phase of the transformer.

(c)
