connect the neutral point of the star (secondary) to u phase of primary, and now apply voltage to primary and measure the voltage between V&R, W&B, V&Y and V&B. when you measure voltage b/w
1. V&R the voltage must be maximum,
2. W&B Should be minimum and
3. voltage between V&Y and V&B should be same
U.V&W are primary (Delta)
R,Y&B are secondary (Star)

How can you test ZNyn11 Vector group transformer?
This vector group test is done to confirm whether the vector group provided in the name plate is correct or not and also to confirm that the winding has not been damaged during transport, installation and erection. Taking a particular example, for Dyn11 transformer we have to apply 3~ 400v to the primary, with primary 'U' & secondary 'u' shorted.... then check the voltage across different terminals such as V-v, V-w, W-w, W-v for Dyn11 configuration (V-v = V-w = W-w)less than W-v.... you can compare the results after drawing the vector diagram for the same...... the purpose of shorting the primary U & secondary u is to nullify the phase shift, to obtain a reference vector...

What is the meaning of test setup?
There may be faults in a design. Verification is required to any design before utilizing it for any application. The verification is done with a test vector or a test pattern. Applying these vectors is called test setup.

What can you determine from an electric field vector at one point?
From an electric field vector at one point, you can determine the direction of the electrostatic force on a test charge of known sign at that point. You can also determine the magnitude of the electrostatic force exerted per unit charge on a test charge at that point.
