Understanding Transformer Vector Group (Part 2)

In Part-2, a video has been attached with this post, in which transformer vector group has been discussed in detail by taking a Power Transformer of voltage rating 132/11.5kV having Vector Group DYn11. Winding vector group have also been introduced in the attached video.

Detail video on the winding vector group will be uploaded separately in a due course of time.

This is a must watch video for the students of the Electrical Engineering as well as for the protection engineer / testing and commissioning engineer to learn this topic with ease.

I will sum up the points regarding the Transformer vector Group
1. It mentions the HV Side Winding configuration. In our case, it is Delta configuration.
2. It mentions the LV side winding configuration. In our case, it is Wye/Star Configuration
and
3.it indicates the phase angle difference between the LV Bushing Terminals and HV Bushing Terminals of transformer.

Note:
Transformer Vector Group does not give the information that how one winding will be connected to each other inside the transformer tank and then how the windings will be brought out to the transformer bushing terminals. For this, concept of Winding Vector Group will be introduced in a separate video.
