For a transformer with a line voltage of 34.5 KV on the primary and a line voltafe of 480V. Calculate Vphase primary and secondary,P,Q, and S for each of the following transformer connections and loads.
1. WYE-WYE transformer, load is 6000 VA power factor is 0.9
2. WYE-DELTA 100HP motor load, pf= 0.88
3. 300kW heater load, Delta-Delta
4. Delta-WYE, wye connected secondary load. Z1=Z2=Z3= 8+j2
