Theoretically, it can be drawn at any angle. Normally, however. it is drawn along the real, positive, axis (i.e. facing East). For series circuits, the reference phasor is the current and, for parallel circuits, the reference phasor is the voltage. For Transformers, it is the flux.

∙ 11y agoA phasor diagram is, to electricity, what a vector diagram is to mechanics. A phasor diagram is used to show the relationship between r.m.s. voltages and currents in a.c. circuits, and can be used to add or subtract like quantities (currents or voltages). They are also useful, because they remove the need to remember complicated a.c. equations which, instead, can be derived from the phasor diagrams using simple geometry (e.g. Pythagoras's Theorem) or simple trigonometric functions (sine, cosine, or tangent); they can also be used to derive impedance and power 'triangles', avoiding the need to remember equations for impedance, power, and power factor.

Is impedance triangle a phasor diagram?
Most definitely not, as resistance, reactance, and impedance are not themselves phasor quantities. However, it is derived from a phasor diagram (by dividing a voltage phasor diagram by the reference phasor, current).

How do you draw phasor diagram of maxwell bridge?
For Series Circuits (example for R-L circuit)Because current is common throughout a series circuit, current is taken as the phasor of reference for series AC circuits. So, we start by drawing a current phasor at 0o. Since the voltage across a purely resistive component (VR) is in phase with the current, we next draw VR in phase with the reference phasor. Since the voltage across a purely inductive component (VL) leads the current by 90o, we draw VL at 90o. We vectorially add phasors VR and VL to give V, the supply voltage. The angle between V and the reference phasor, I, is the phase angle. To create an impedance diagram, divide each voltage by the reference. To create a power diagram, multiply each voltage by the reference.For Parallel Circuits (example for R-L circuit)Because voltage is common across each branch of a parallel circuit, voltage is taken as the phasor of reference for parallel AC circuits. So, we start by drawing a voltage phasor at 0o. Since the current through a purely resistive branch (IR) is in phase with the voltage, we next draw IR in phase with the reference phasor. Since the current through a purely inductive branch (IL) lags the current by 90o, we draw IL at -90o. We vectorially add phasors IR and IL to give I, the load current. The angle between I and the reference phasor, V, is the phase angle. To create an admittance diagram, divide each current by the reference. To create a power diagram, multiply each current by the reference.

How do you identify step up or step down transformer from phasor diagram?
Number of turnsAnswerI assume that you have a phasor diagram of a transformer, and wish to identify the primary phasors and the secondary phasors?For a three-phase transformer, this is fairly straightforward, provided the usual procedure for drawing a phasor diagram has been followed. Whenever you start to draw anysort of phasor diagram, you usually start by selecting a phasor of reference and draw that in the horizontal positive direction. For a three-phase transformer, the phasor of reference is usually the primary phase voltage A (or however else it is identified: R, red, or whatever). The remainder of the primary phase voltages are then drawn, enabling the primary line voltages to be constructed (which, in the case of a primary delta are the same as the primary phase voltages!). So if you can identify the phasor of reference, then you have identified the primary-winding phasor diagram. As the primary and secondary voltages are not usually drawn to scale, relative to each other, you can't assume a turns ratio from the phasor diagram. The labelling might also help, as high-voltage phase and line voltages are identified by upper-case letters, while low-voltage phase and line voltages are identified using lower-case letters -but, remember, these identify high- and low-voltages, not which is primary and which is secondary (primary winding is connected to supply/secondary winding is connected to load).For single-phase transformer, the phasor of reference is the flux set up in the magnetic circuit, and voltages/current phasors are drawn relative to this. In this case, the primary line and induced voltages are usually identified as V1 and E1, and the secondary induced voltage as E2 (sometimes, the Es and Vs are interchanged). Again, the lengths of the primary and secondary voltages are not necessarily to scale relative to each other.
