Transformer connection with Ynd5 vector group

I really appreciate "" for presenting a detailed overview of transformer connections, vector group, polarity marking with video tutorials.

The video as uploaded and shared to public by "" will be much more useful for young generation as well for experienced professionals those who are having the doubts over the transformer connection/ vector group in the corner of their mind.

Regarding the subject, if "" presents a video tutorial for Ynd5 transformer vector group in the same manner it has presented for Dyn11 it will be of more useful as this connection (Ynd5) is made in such a way that it is complex by itself

Please extend the help to electrical community

@Govind , thank you for your comments! We will try our best to do a video on the Ynd5 connection for the purpose of learning and understanding transformer vector groups. The Dyn11 videos were quite long because it was intended to serve as a foundation for other videos regarding transformer vector groups. Please let us know how can be enhanced and improved moving forward. Thanks.
Really appreciate your kind reply.
"The Dyn11 videos were quite long " no one can explain in less time than this video length, it is quite good and the way it is represented will go deep in to electrical engineer mind.

The basics is explained very well. If "" moves ahead by explaining the complex connection and the vector rotation of Ynd5 as it s not Dy it is Yd will give result to the understanding of most common vector groups of transformer

Other suggestion is "VECTOR GROUP" of transformer by considering a bare winding and start explaining how to make vector connection having bare primary wining and bare secondary winding then connecting to star or delta in the primary or secondary and proceeding with how a required vector group of the transformer is formed say Dyn11 or Dyn1 or Ynd5 to draw the vector group diagram and connection will lead to understand an engineer to make the as required vector connection/ group of transformer with primary and secondary winding (A1A2 B1B2 C1B2 : a1a2 b1b2 c1c2) in hand.


Hi..i am a new user here. As per my knowledge the central point may be connected outside of the transformer to a system neutral. Z or z: Zigzag winding, or interconnected star winding. Similar to a wye winding, but two windings form each phase are arranged so that the three legs are "bent" when the phase diagram is drawn.
