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.

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:
