Single 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 that encapsulates the frequency The single-phase induction motor can be made to be self-starting in numerous ways. One often-used method is the Split Phase motors. Another method is the Capacitor Start Induction Run Motors. Now if we substitute Q >10 then 1/Q 2 = 1 / 100 and hence we can neglect this value, thus neglecting 1/Q 2 we get r 2 r 3 c 4 which is same as we have obtained in Maxwell bridge hence Hay’s bridge circuit is most suitable for high inductor measurement. Let us know more about Hay’s bridge circuit diagram of Hay’s bridge that will be very useful in understanding the Hay’s bridge phasor Phasor Diagrams It is sometimes helpful to treat the phase as if it defined a vector in a plane. The usual reference for zero phase is taken to be
the positive x-axis and is A transformer supplying a three-wire distribution system has a single-phase input (primary) winding. The output (secondary) winding is center-tapped and the center tap connected to a grounded neutral.As shown in Fig. 1. either end to center has half the voltage of end-to-end. Fig. 2 illustrates the phasor diagram of the output voltages for a split-phase transformer. 3/2/2018 1 LESSON 11: TRANSFORMER NAME PLATE DATA AND CONNECTIONS ET 332b Ac Motors, Generators and Power Systems 1 Lesson 11_et332b.pptx LEARNING OBJECTIVES 3 the armature (stator) winding.
