Question

The magnitude of the line voltage at the terminals of a balanced Y-connected load is 660 V. The load impedance is 240-j70 Ω/Φ. The load is fed from a line that has an impedance of 0.5 + j4 Ω/Φ.
A) What is the magnitude of the line current?
B) What is the magnitude of the line voltage at the source?

Answer 1

Answer:

A) magnitude of the line current = 15.24 A

B) 6583.94 v

Explanation:

Given data :

magnitude of line voltage at terminal = 6600 v

load impedance = 240 - j70 Ω/∅

impedance of load fed from a line = 0.5 + j4 Ω/∅

attached below is the detailed solution
