Question

 A balanced, positive-sequence, Y-connected voltage source with Eab = 480∠0o volts is applied to a
balanced-∆ load with Z∆ = 30 ∠40o Ω. The line impedance between the source and load is ZL = 1 ∠850 Ω.
for each phase. Calculate the line currents, the ∆ -load currents, and the voltages at the load terminals.
Recall that ZY = Z∆/3 

Expert Solution
Step 1

In this question,

A balanced, positive-sequence, Y-connected voltage source

Eab = 480∠0o Volts. 

balanced load Z∆ = 30 ∠40o Ω.

The line impedance between the source and load is ZL = 1 ∠850 Ω.

Calculate the line currents, the ∆ -load currents, and the voltages at the load terminals.

Assume ZY = Z∆/3
