I'm not sure if this is the most suitable place to ask, but I have a
few questions with respect to drawing and interpreting clock diagrams
of three phase transformer connections.
1. Are the following the only types of connections that are used in
industry?
Dy11, Dy5, Yz0, Yz5, Yd11, Yz5
2. For the clock diagram on the primary side, is phase A always
pointing to the 12 O'Clock position?
Responses would help so much for my understanding. Thanks. |
