Question

5. In #4 H1 and H2 have 4800 volts and turn ratio is 5:1. What is the line voltage on the secondary?

6. In #5 line in amperage is 60 Amps find the line current out?

7. In #3 H1 and H2 have a line voltage 12 kV and phase current of 100 A. The turn ratio is 10:1(pf=.8). What is the apparent power in a secondary load? What is the real power in the primary?

8. In #2 if the secondary load is 120 kVA, turn ratio is 10:1 and line voltage on secondary is 4800 V (pf=.8) Find the line voltage in primary and the real power in the primary.

9. Find the current in a 20 UF Cap connected to a 120 AC line?(60Hz)

10 What is the impedance if connected to a 100 Ohm resistor in series?

11. Draw an open delta transformer connection. Label the phases A-B-C.

12. If both transformers are rate at 350 VA what is the max VA that be used?

13. Given a transformer with two secondary windings of 110 VAC and 50 VAC and a primary of 2200 VAC. Show how you could get 2260 VAC. (Mark H1 and H2 and X11 and X12 and X21 and X22)
