The phase voltage at the terminals of a balanced three-phase Y-connected load is 240020° V. The load has an impedance of 16 + j12 0/y and is fed from a line having an impedance of 0.10 + j0.80 N/4. The Y-connected source at the sending end of the line has a phase sequence of abc and an internal impedance of 0.02 + j0.16 0/p. Use the a-phase voltage at the load as the reference and calculate: (a) the line currents laa, IbB, and Icc. (b) the line voltages at the source Vab, Vbc, and Vca. (c) the internal phase-to-neutral voltages at the source Va'n, Vb'n, and Ven.

Question
Transcribed Image Text:The phase voltage at the terminals of a balanced three-phase Y-connected load is 240020° V.
The load has an impedance of 16 + j12 Q/4 and is fed from a line having an impedance of 0.10
+ j0.80 Q/4. The Y-connected source at the sending end of the line has a phase sequence of abc
and an internal impedance of 0.02 + j0.16 0/p. Use the a-phase voltage at the load as the
reference and calculate:
(a) the line currents laa, IbB, and Icc.
(b) the line voltages at the source Vab, Vbc, and Vca.
(c) the internal phase-to-neutral voltages at the source Va'n, Vb'n, and Vc'n.
Note: RMS values are not required
