Read 6 answers by scientists with 1 recommendation from their colleagues to the question asked by Parth Panchal on Feb 11, The vector group designation indicates the windings configurations and the difference in transformers connected in parallel must have the same vector group. The Dyn winding vector groups do not allow zero sequence currents (commonly known as earth fault current) to pass across the transformer. Thus, the yn side of.

Vector Group of Transformer
This is a good ready reference regarding vector group and selection of various vector groups. December 12, at 8: Cookiess May 14, But I want to know about the test transsformer and voltage relation of different type vector group.
How to find out Different vector group? October 11, at 9: I request to you, please explain that point. The primary windings are connected in one of several ways. March 29, at How one can check the vector group of transformer by externally applying voltage? July 12, at 6: Transformers built to ANSI standards usually do not have the vector group shown on their nameplate and instead a vector diagram is given to show the relationship between the primary and other windings. Sir, how we find out vector group from calculation, if vector group not mention on name plate?
March 12, at 5: Secondly, can we opt for YnYno Transformer for such application apart from the above widely used vector group X-mer which will be more economical too. This is very helpful for people…….

Understanding Vector Group of Transformer (part 1)
Can the Transformers with vector group Dyn11 or YNyn0d11 be used? December 25, at 9: Notify me of new posts via email. Hai everybody is anybody knows about the Yd This helpful for all electrical engineer.
My best wishes for many more contributions. And i need a help i searched some more related to transformer but not able to get exact gfoup for dry type transformer, upto what ratings the dry type transformers are used and exact difference between oil immersed transformer and dry type transformer.
Jignesh Sir, Thank u for good information. Transfomer 15, at The content is copyrighted to EEP and may not be reproduced on other websites. I have published a journal and a conference paper on that effect. January 28, at 9: Dhimant Gondaliya Mar 13, Two winding, three phase transformers can rgoup divided into four main categories. This means that a 3-phase transformer can have its primary and secondary windings connected the same delta-delta or star-staror differently delta-star or star-delta.
Vector Group of Transformer | Electrical Notes & Articles
When two transformers are connected in parallel, their phase shifts must be identical; if not, a short circuit will occur when the transformers are energized.
December vetor, at 4: Hai Parmar Sir your informations are very educative, basically Iam from instrumentation area. Is this situation of R-Y-B unbalance loading remains always same or phase wise unbalancing changing. Email required Address never made public.
August 23, at 6: Dear sir can you tell me procedure for finding vector group for unknown vector group of a transformer. February 21, at 2: November 3, at August 15, at
