A small industrial unit draws an average load of 100 A at 0.8 lagging pf from the secondaries of its 2000/200 V, 60 kVA Y/? transformer bank. Find:
(a) The power consumed by the unit in kW,
(b) the total kVA used,
(c) the rated line currents available from the transformer bank,
(d) the rated transformer phase currents of the ?-secondaries,
(e) per cent of rated load on transformers,
(f ) primary line and phase currents, and
(g) the kVA rating of each individual transformer.
