Transformer vector group determination|Electrical engineering|Electrical technology

In video we have shown the procedure to determine vector group of a transformer. Only Ynyn0, Ynyn6, Dyn1 and Dyn11 transformers have been shown as example. The other vector grouos are also determined in the same manner.
The explanation given in the video is applicable for all the below mentioned topic.
1. How transformer vector group is tested.
2. Testing of transformer vector group.
3. Transformer vector group identification.
4. How to determine transformer vector group.
5. Star Star and Delta star transformer.
6. Transformer testing.
7. Vector grouping of a three phase transformer

Sir , you have wonderful explanation power. I passed out BE under retired IIT prof. But even after did 10 years job in transmission sector , Gujarat , still I didnt understand the vector group and vector group test. But today I understand the same and clear the funda. No matter your video has less attractive graphics , but if one want to clear the funda , then your videos are the best one among all CZcams clips.
Thanks a lot , m going subscribe 👌

[@indranathmoulick4915]

Such a high voltage topic explained in such a low voltage manner so that anyone can understand easily....
👍👍

Sir eventhough it is very diffult subject ,you posted wonderful videos,Thankyou sir

[@mirhamidseyedabbaszadeh8064]

That was very useful. Thank you very much for the video.

[@Olavotemrazaodenovo]

Thank you from Brazil.

[@vivroursolen6177]

Thank you for sharing your knowledge Sir.

[@prabhakarangovindaraj9238]

Sir you are making really wonderful videos ,,😂😂😂

[@prabhatsingh5377]

Sir kindly make YNd1 and YNd11 vector group test also . Your teaching skills are excellent 👌

[@ekosan991]

Keep on your explanation is v good

[@electricaltechnologyandind5335]

Thanx

[@surendrakverma555]

Very good. Thanks 🙏🙏🙏🙏🙏

[@swaransingh1690]

Very good 👍👍👍

Sir why we short the 1u and 1v winding in Dyn11 vector group testing??

[@jinoyjose5468]

Thanks for your explanation,during testing how much voltage we generally applies to a 11/.4 kv 2mva transformer,

[@electricaltechnologyandind5335]

I have seen 440V line to line in one test report.

Application of different types of vector group transformer

[@muthukumarasamyveeraswamy6304]

Sir, Is it possible to have Yd0 and Dy0 vector connections, if not possible what is the reason behind that?

[@learnbyshiva725]

Sir thanks very much

[@ManishKumar-ye2uj]

How to check double winding transformer vector group can plz give me a hint

[@bhabeshbehera7611]

Dear sir, Pls. show the video vector group of -D/Ydiii Transformer.

[@electricaltechnologyandind5335]

It is a very uncommon vector group. Not used often, but you can check it by theke technique shown in the video. However I am keeping your query in mind, and I shall try to make a video

[@shashankkumar7770]

Thanku sir

[@chandrakantmuniya3975]

Why such vector group is there . What are importantes of such vector group , Sir ..?

[@AbdulRashid-pw8dq]

Why we need vector group?, why we're going for shift ?, what will happen if we use same phase angle as of generated without shifting?. What's necessary of phase shift for transmission and distribution. Explain me

[@sriramprakash97]

With out phase shift we cannot produce rmf

[@AbdulRashid-pw8dq]

@@sriramprakash97 i don't think so, then you're saying generation Voltage and current from generator doesn't have RMS?

[@anuragverma4863]

@abdul ,It is imoortant to test the vector group because of the unwanted circulating current ,which produces heating effect . Power grid is supplying the same vector group and we are connecting our transformer to that .so vector should be matched and no phase shifting and no circulating currents .

@@anuragverma4863 Sir how to calculate fault current of a plant and how with detailed explanation

[@anuragverma4863]

@@sriramprakash97
Its a long calculation. We dont talk about the plant , we calculate fault current with respect to source . Source is key factor and it supplies the fault current . So while selecting the circuit breaker or any panels ,consider transformer fault current , generator fault current , cable also plays important role, and during fault ,motor also supplies fault current ,rather than to take supplies.
Transformer fault - full load current / percentage impedance .
Gen fault - full load current / reactance, X ''
Cable - MVA(short ckt) = (KV)^2 / Zcable.
Add it. For motor , generally add 4* full load of transformer of you dont have data of motor. Thats it.
