Example 33.21. Two electric furnaces are supplied with 1-phase current at 80 V from a 3-phase, 11,000 V system by means of two single-phase Scott-connected transformers with similar secondary windings. When the load on one furnace is 500 kW (teaser secondary) and on the other 800 kW (secondary of main transformer) what current will flow in each of the 3-phase lines (a) at unity power factor and (b) at 0.5 power factor? Neglect phase displacement in and efficiency of, the transformers. (Electrical Engineering, Madras Univ. 1987) Solution. The connections are shown in Fig. 33.26 and the phasor diagrams for unity and 0.5 p.f.
