Question: A balanced Y-connected voltage source with E ag = 277/0 0 volts is applied to a balanced-Y load in parallel with a balanced- load, where

A balanced Y-connected voltage source with E _ag = 277/0 ⁰ volts is applied to a balanced-Y load in parallel with a balanced-∆ load, where ZY = 20 + j10 and ZΔ = 30 − j15 ohms. The Y load is solidly grounded. Using base values of Sbase1φ = 10 kVA and VbaseLN = 277 volts, calculate the source current Ia in per-unit and in amperes.
