What is difference between phasor and vector?
What is difference between phasor and vector?
Although the both the terms vectors and phasors are used to describe a rotating line that itself has both magnitude and direction, the main difference between the two is that a vectors magnitude is the “peak value” of the sinusoid while a phasors complex magnitude is the “rms value” of the sinusoid as they deal with AC …
What is the vector group of distribution transformer?
The transformer vector group is indicated on the Name Plate of transformer by the manufacturer. The vector group indicates the phase difference between the primary and secondary sides, introduced due to that particular configuration of transformer windings connection.
What is meant by Dyn11 vector group?
Dyn11 is vector group notation of tansformer.It means LV winding,which is star connected (written in small letters means LV side and vice versa)is 30 degrees lagging by HV winding which is delta connected.In India we go for +-30 deg connection of transformer.
How do you draw a vector group in a transformer?
If we go through the vector diagram of secondary line voltages of both transformer, we will easily find that there will be a clear 30o angular difference between the line voltages of these transformers….Vector Group Test of Transformer.
| GROUP | Connection | Connection |
|---|---|---|
| 1 ( 30o) | Yd1 | Dy1 |
| 6 ( 180o) | Yy6 | Dd6 |
| 11 ( – 30o) | Yd11 | Dy11 |
Is phasor a vector diagram?
Phasor diagram is also known as vector diagram. A phasor diagram is used to show the phase relationships between two or more sine waves having the same frequency. Every phasor in the diagram will have the same angular velocity because they represent sine waves of identical frequency.
Can a phasor be a vector?
Phasors are rotating vectors having the length equal to the peak value of oscillations, and the angular speed equal to the angular frequency of the oscillations. They are helpful in depicting the phase relationships between two or more oscillations.
What is Dyn11 and Dyn1?
About your question, the difference between Dyn1 and Dyn11 is the relationship between the primary and secondary currents. For Dyn1, the secondary current, wye side, LAGS the delta side by 30 degrees whereas for a Dyn11, its the opposite, secondary currents, wye side, now LEAD the delta side by 30 degrees.
Why DYn11 is used in transformer?
The DYn11 satisfies the requirements for distribution system operation i.e it provides easily accessible phase voltage from the LV side, and eliminate the triplen harmonics from propagating to the HV network.
Why is phasor a vector?
What is vector and phasor diagram?
In physics and engineering, a phasor, is a complex number representing a sinusoidal function whose amplitude, angular frequency, and initial phase are time-invariant. Phasor diagram is nothing but a graphical representation of sine wave with frequency and amplitude. Phasor diagram is also known as vector diagram.
