There are various ways in which you can connect a three-phase transformer's primary and secondary windings, or in which you can connect three single-phase Transformers to create a three-phase transformer bank. For example: wye-wye, wye-delta, delta-delta, delta-wye, etc.
For each connection, there is a natural phase shift between the primary and secondary line voltages. This is called the angular displacement (or 'phase displacement') of the transformer connection.
If you wish to parallel two three-phase transformers, or two three-phase transformer banks, then their angular displacements must be the same (there are also other requirements not relevant to this answer).
A vector group is a method of specifying a three-phase transformer (or transformer bank) method of connection and its angular displacement. Transformer connections from the same group can be paralleled. Those in different groups cannot

How you will check the vector group of transformer is DZn10?
To check if a transformer has a vector group of DZn10, you'll need to measure the phase relationships between the primary and secondary windings. This can be done using a phase rotation meter or a voltmeter and an ammeter to analyze the phase angles. Specifically, verify that the secondary winding is connected in a zigzag configuration and that the neutral point is grounded, confirming the DZn designation. Additionally, check the vector group’s characteristics to ensure it matches the expected phase shift and connections.
Why mentions the nameplat of transformer in vector group?
A transformer's 'nameplate' lists all the data necessary to identify the rating, connections, etc., of a transformer. Part of this data is the 'vector group' information which applies to three-phase transformers, and which, in simple terms, tells us whether or not the transformer can be connected in parallel with another.
How do you implement vector?
import java.util.Vector; public class VectorTest { /** * @param args */ public static void main(String[] args) { //instantiating a vector Vector vct = new Vector(); //Add objects to a vector vct.add("One"); //getting values from the vector String val = (String) vct.get(0); //vector size System.out.println("Vector size is: " + vct.size()); //removing elements from a vector vct.remove(0); } }
Why required the vector group?
The vector group of a transformer is required to specify the phase shift between the primary and secondary windings. This information is crucial for operating multiple transformers in parallel and ensuring they are in phase with each other. The vector group helps maintain the proper voltage and current relationships between transformers in a power system, ensuring efficient and stable operation.

What is mean by Vector group YnaoD11?
Vector group YnaoD11 represents a specific configuration of transformer windings. The "Y" indicates a star (wye) connection on the high voltage side, "na" indicates a zigzag connection on the low voltage side, and "oD11" specifies the phase shift angle between high and low voltage windings. This vector group is commonly used in special applications where zero sequence impedance is required for system grounding and fault protection.
Why is the magnetic field a vector quantity?
Magnetism is a force. Vector notation is required to indicate magnitude and direction of a force.
Is curl of vector function F must perpendicular to every vector function f?
No, the curl of a vector field is a vector field itself and is not required to be perpendicular to every vector field f. The curl is related to the local rotation of the vector field, not its orthogonality to other vector fields.
