Transformer Connection Group Dyn11

Heure publiée:2019-03-01 10:42

Dyn11 is the wiring group of the transformer, meaning the following:


1. D is the high-voltage side delta connection of the transformer.


2. y indicates that the low voltage side is a star connection.


3, n is a neutral point.


4, 11 means that the vector difference between high and low voltage is 30 degrees, the voltage vector displacement of the low voltage winding is 30 degrees behind the high voltage, and the method of clock indicates that the voltage vector of the high voltage side points to the 12 o'clock of the clock, and the line voltage vector of the low voltage side Point to the 11 o'clock clock.
