Single Phase Phasor Diagram. The rotor moves through 90 in clockwise direction to align with the resultant air gap field which now lies along the axis of phase b. Answer 1 of 8.
E 1 is represented by v 1. Circuits at the end of this chapter you should be able to. The phase of an alternating quantity at any instant in time can be represented by a phasor diagram so phasor diagrams can be thought of as functions of time.
A vector plot of voltages and currents within one phase is called a phasor diagram.
We will draw the phasor diagram of transformer under no load condition in few steps then by combining all the steps together we will draw a final figure. Important points for phasor of transformer. A sinusoid is specified by an amplitude and a phase. The rotor is stable in this position and cannot move until phase a is de energised.
