Is the phasor a time-domain or frequency-domain quantiy?
It is a frequency-domain quantity. In Basic Engineering Circuit Analysis by Irwin, the time domain is written as A*cos(wt+/-THETA) and the frequency domain is written as A*phasor(+/-THETA).A series of phasor measurements, taken at regular intervals over time, can sometimes be useful when studying systems subject to variations in frequency. The electric power system is one example. The power grid nominally operates at 50Hz (or 60Hz), but the actual frequency is constantly changing around this nominal operating point. In this application, each individual phasor measurement represents a frequency domain quantity but a time series of phasor measurements is analyzed using time-domain techniques.

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).
When did Phasor Zap happen?
Phasor Zap happened in 1978.
When was Phasor Zap created?
Phasor Zap was created in 1978.
What is mean by dynamic phasor?
Phasor diagram is graphical representation of various electrical parameters in terms of their magnitude and angle.
Why do you use phasor Diagram?
phasor diagram is nothing but the vectorial representation of time-varying periodic signals(most common are sine and cosine) , whose magnitude is given by the amplitude of the signal and the direction (angle..) is given by the phase difference. this makes life a lot easier , calculations in vector-algebra domain is more easier when compared to trigonometric domain because here we can resolve any 'n' no. of vectors and by performing simple algebra of addition and subtraction gives us the desired result. Whereas in trigonometric domain we need to expansions like sin(A+B),cos(A-B) etc etc which is a laborious task
What are the phasor diagrams and sinusoidal expressions of the three voltages?
The Phasor diagram explains the relation between voltage and current. This comparison happened in the Sinusoidal functions and solved using the Sinusoidal expression.
What is a phasor diagram and why you draw it?
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.
What is the difference between vector and phaser diagram?
A(t) = Am sin(ωt ± Φ) representing the sinusoid in the time-domain form. But when presented mathematically in this way it is sometimes difficult to visualise this angular or phase difference between two or more sinusoidal waveforms so sinusoids can also be represented graphically in the spacial or phasor-domain form by aPhasor Diagram, and this is achieved by using the rotating vector method.Ansh

How do you add and subtract two sinusoidal ac waveforms graphically and by phasor diagram?
I already have the graph drawn on graph paper with 2 waves on , my phase shift is 1.5 and 180degrees. Anyone know how to add and subtract the sinusoidal ac waveforms on the graph, and by phasor diagram?
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.
