What is a vector group? And what is the meaning of Dyn11? And what is the meaning of Yd11?
The Vector Group
It is a term given to the directional group of electric power transformers, and their compatibility is a condition of connecting transformers in parallel
And the Vector Group method for connecting
High and low voltage of the transformer as well as the phase shift angle
phase displacement
Between low voltage windings, high voltage windings, or otherwise, the lag angle coils or lead offers low voltage coils over high voltage coils
How to read the directional group of power transformers?
D Hv side delta, Y
Side star Hv, d lv
Side delta
y lv the side of the star
0-12 the phase displacement in terms of clock position is a multiple of 30 degrees
The phase offset of the LV winding in reference to the HV winding (lag or lead
Practical example of what we mean by Dyn11
Religion 11
D delta high voltage side is connected
The high-pressure side connects delta-triangular files
A low voltage side star is connected
Hand low pressure link files astral star
n is neutral
The neutral, neutral, or cold line
11 stage offset
11 o'clock 11 'Oclock Phase shift angle: the secondary curtain winding voltage advances the primary delta by 30 °
How do we calculate the phase displacement?
The product of the last number 11 x [30] = 330
