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

phase shift – Transformer Design – Electrical Engineering Stack Exchange

The phase windings of a polyphase transformer can be connected internally in different configurations, depending on what characteristics are needed from the transformer. The vector for the high voltage winding is taken as the reference vector. In electrical engineeringa vector group is the International Electrotechnical Commission IEC method of categorizing the high voltage HV windings and low voltage LV winding configurations of transfofmer transformers. 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.


Ezeh Doris Oluchi Jan 09, This is such a well written article. Khan Jan 04, Proud to be an IndiBlogger electricalnotes. Dyn1, the phase difference will be nullified. March 22, at March 12, at 9: November 4, at 7: In this modern times is it need for sending power both ways in a transfomer. Amorphous metal transformer Austin transformer Autotransformer Buck—boost transformer Capacitor voltage transformer Distribution transformer Delta-wye transformer Energy efficient transformer Flyback transformer Grounding transformer Instrument transformer Current transformer Potential transformer Isolation transformer Linear variable differential transformer Pad-mounted transformer Parametric transformer Planar transformers Rotary transformer Rotary variable differential transformer Scott-T transformer Solid-state transformer Trigger transformer Variable-frequency transformer Zigzag transformer.

March 26, at 9: Here’s the phasor diagram that explain the 30 degree phase shift: 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.

Likewise, earth tdansformer protection on the primary side is not affected by earth faults on the secondary side. Download Now White Paper: If you say the rotation anti-clock then TR. June 12, at 4: Thanks Fransformer Could you help me for my case. The 11 indicates the LV winding leads the HV by 30 degrees.


October 24, at 8: May 3, at April 19, at 4: The minute hand is set on 12 o’clock and replaces the line to neutral voltage sometimes imaginary of the HV winding. October 7, at 9: Please help improve this article by adding citations to reliable sources.

Why DYN11 vector group used in Distribution transformer?

But I have spent much time in field of distribution. Radhakrishnan K A Dec 10, I have installed and operated no.

Bob Robinson Jul 09, Jignesh Parmar has completed M. Dy1, Yd5 etc on asymmetrical faults and especially as regards one-phase-to-ground faults, which are the most frequent faults. January 25, at 4: January Learn how and when to remove this template message.

Also pl explain the significance of 30 degree multiple.
