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.

Thanks for your explanation about vector group. What will be vector group for that.

March 14, at 3: I have one straight but not so simple question. Muralikrishnan Nov 03, September 14, at If You find this content in any other site,it makes the page you are viewing an infringement of the copyright.

We evctor a DYN5 Transformer which is used as a step down transformer Because of this, transformers are manufactured with a variety of winding configurations to meet these requirements. Don’t have an account? Dear Sir, Please rgoup which type of load is suitable for which vector group of transformer.

How will this be affected by the vector lag, in an Dyn11?

Vector Group of Transformer | Electrical Notes & Articles

Fabrice de Lapparent Jun 21, This means that a 3-phase transfomrer can have its primary and secondary windings connected the same delta-delta or star-staror differently delta-star or star-delta. Sorry, your blog cannot share posts by email.


Aqeel Sep 02, September 3, at 8: August 14, at 3: February 27, at 7: The high-voltage HV winding is designated with an uppercase letter, followed by medium or low-voltage LV windings designated with a lowercase letter.

Understanding Vector Group of Transformer (part 1)

September 15, at 6: When dym11 try connect different transformer in parallel. Why do dd and yy winding cannot have 30 or 60 degree phase shift in vector group formation.

Jignesh Sir, Thank u for good information. As you know the distribution system normally on HV side connected in parallel and LV side radial. The only factor affecting the choice between one or the other is system phasing, i.
