When constructing a three-phase phasor diagrem, it is usual to construct the phasors in the following sequence:
A) phase voltage, phase current, line voltage, line current.
B) line voltage, line current, phase voltage, phase current
C) phase voltage, line voltage, phase current, line current.
D) phase current, line current, phase voltage, line voltage.

Question

Quizplus · Accepted Answer

The usual sequence for constructing a three-phase phasor diagram is to first draw the phase voltage phasors, followed by the line voltage phasors. Next, draw the phase current phasors, followed by the line current phasors. This sequence allows for a clear understanding of the phase relationships and helps to identify unbalanced conditions (such as phase shifts or magnitude differences) in the system. Therefore, choice C is the best option.
