Phase sequence and Polarity of Three Phase System
Phase sequence is the sequence in which the voltages in a three-phase system reach their peaks. Each phase-shifted by 120 degrees with respect to the other two.

Phasor and Complex Representation of Three Phase Supply
Three sinusoidal voltages with equal amplitude and frequency, but a phase difference of 120∘ (or 2π/3 radians) between them, constitute a three-phase supply. Common names for them include Phase R, Phase Y, and Phase B. For such a supply, the general form is as follows: Graphical Representation Phasor representation is a way of representing sinusoidal … Read more
