What happen if we use DYn1 vector group for distribution transformer? that the structure DYn11 is also simple in comparison with some other vector groups. What is the meaning of Dyn11 of Transformer Answer / devidas. First symbol/ symbols, capital letters: HV winding connection. Second symbol/symbols, small. In theory a three-phase transformer works like three separate transformer’s rating plate. Dyn Yyn0. Yd1. Yd Dz0. Yz1. Yz

Vector group – Wikipedia

But I have spent much time in field of transofrmer. March 14, at 3: I would like to add another interesting point: Dear jignesh brother, Your electrical notes are very very helpful. This can be done by the positive effect of transformers of vector group 1, 5, 7 and 11 e. Aqeel Sep 02, From the Vector group YznII of a particular transformer, how would you know that the Ratio test on the HV side of a transformer has failed?

Sir, As you said: Once again thanks to u.

Saha Feb 03, The vector group provides a simple way of indicating how the connections of a transformer are arranged. Students Click Here Join Us! November 14, at All theories claim that trransformer is a phase displacement of deg between the voltage in primary and secondary.

By continuing to use this website, traansformer agree to their use.

What is the meaning of Dyn11 of Transformer.

Khan Jan 04, I have been an avid reader of many an article published by you and every article is just great. Dd0 no phase displacement between HV and LV.

Please check the additive polarity symbolic daigram. Gujarat Gas Co Ltd. Tech Power System ControlB.


The 11 indicates the LV winding leads the HV by 30 degrees. Thanks for sharing this information. May 6, at 7: I request to you, please explain that point. Hardly any power system adopts such a large variety of connections.

Vector Group of Transformer

Thanks for your blessing. I would like to ask one thing regarding distribution transformers. What is the meaning of Dyn11 of Transformer It means LV winding,which is star connected written in small letters means LV side and vice versa is 30 degrees lagging by HV winding which is delta connected. The phase relationship of the two voltages depends upon which way round the coils are connected. Normally Dyn11 vector group using at distribution system.

Facebook Email Twitter LinkedIn. The voltages will either be in-phase or displaced by degree. March 24, at 6:
