3 phase phasor diagram

In physics and engineering, a phasor (a portmanteau of phase vector), is a complex number representing a sinusoidal function whose amplitude (A), angular frequency (ω), and initial phase (θ) are time-invariant.It is related to a more general concept called analytic representation, which decomposes a sinusoid into the product of a complex constant and a factor depending on time and frequency. A three-phase transformer is built for a specific connection and voltage transformation and the unit will have a nameplate with the internal connections shown. When a single unit or bank of three is used, there are four types of connections. The four basic connections are: Y-Y, Y-∆, ∆-Y, and ∆-∆.

3 phase phasor diagram. 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. "vector-algebra," phasor diagrams are combined with algebraic expressions to explain, in simple terms, how currents are calculated in the respective three phase circuits. •Phasor diagrams require a circuit di agram. The phasor diagram… has a indeterminate or vague meaning unless it is accompanied by a circuit diagram. •The assumed directions and polarities are not critic al, as the phasor diagram will confirm if the assumptions were correct, and provide the correct magnitudes and phase relations.
