Three-Phase The key to understanding three-phase is to understand the phasor diagram for the voltages or currents. In the diagram at the right, a, b and c represent the three lines, and o represents the neutral. The red phasors are the line or delta voltages, the voltages between the wires. The blue phasors are the wye voltages, the voltages to neutral. If a 1-Phase Supply is 230V, Why is 3-Phase 400V & Not 690V? The vector addition based on the phasor diagram for 3-ϕ supply system, where each line has 230V, the vector difference is almost 400V for each phase (either Phase 1 & Phase 2, Phase 2 and Phase 3 or Phase 3 and Phase 1). Phase Sequence in Three-Phase System - Electrical Academia When we are given the line voltage and phase sequence of a three-phase source, as in Figure 2 (a), we can draw a phasor diagram by placing one phasor (usually VBA) along the reference axis. As we read clockwise around the phasor diagram of Figure 2 (b), all the first subscript letters of the voltage phasors must follow the specified phase sequence.
