What is the meaning of the Y D11 on the transformer?
Transformer Y / D11 Y ----- primary side connection, star type, D secondary side connection, triangle 11 is the primary and secondary side of the phase difference of the side line voltage lag secondary side 330 degrees (or lead 30 degrees).

Yn d11 said: high side is a star-shaped wiring with a neutral point of the lead-out, low-side side of the triangle wiring. Using 11-point connection, that is, high-voltage side of the line voltage ahead of the low voltage side line voltage of 30 degrees.
