Three single-phase, 78 kVA, 19.05 kV/415 V, 50 Hz transformers are connected to form a threephase transformer bank as shown in Figure 1. As shown
Three single-phase, 78 kVA, 19.05 kV/415 V, 50 Hz transformers are connected to form a threephase transformer bank as shown in Figure 1. As shown in Figure 1, three 78kva, 19.05kV / 415V, 50hz single-phase transformers are connected into a three-phase transformer group. Primary windings pl, p2 and p3 are connected in Star and secondary windings s1, s2 and s3 are connected in Delta. The primary windings pl, p2 and p3 are connected in a star shape, while the secondary windings s1, s2 and s3 are connected in a triangle shape.

The three-phase transformer feeds the three-phase load through a cable. The three-phase load, represented by three star-connected Zlood elements, consumes a total of 110 kVA apparent power at the rated secondary voltage, with a lag power factor of 0.8. Determine the total three-phase reactive power consumed by the load [kVAr]: Determine
