When we want to buy a transformer or want to seek something about the transformer , we often can see a word: dyn 11 transformer.To the newcomer of the transformer, it's hard for them to figure out what is the meaning of dyn 11 transformer?

 

In fact, A Dyn11 transformer refers to a specific type of three-phase transformer connection. Here's a explaination of what it means:

D: Delta connection on the primary side ( or we can call it: high voltage).

y: Star connection on the secondary side (or we can call it: low voltage).

n: Neutral point is brought out.

11: Indicates the phase shift between the primary and secondary windings. In this case, the secondary lags the primary by 30 degrees (11 * 30°).
