8. A single-phase 480 V 600 kVA pf = 0.8 leading load is to be served from a single-phase 2400 V source using a single-phase ideal transformer. Complete the circuit diagram and provide the transformer turns ratio. Place values for the phasor primary and secondary voltages and currents on the diagram. LOAD 9. A three-phase 2.4 kV 9000 kVA load is to be served from a three-phase 12.47 kV source using three single-phase transformers, each with turns ratio 3:1. a. the HV windings should be connected wye delta (circle) b. the LV windings should be connected wye delta c. the HV winding current (A) is 3750 2165 1250 722 417 241 3750 2165 1250 722 417 241 d. the LV winding current (A) is 10. A 3-phase 345 kV transmission line uses a bundle of two cardinal conductors for each phase; the ampacity of a cardinal conductor is 800 A. Positive sequence equivalent circuit values are Z = 160 2; Y/2 = j0.345 mS. Find: SRATED= MVA SIL = MVA SSSL MVA
