Why we use mostly YNd1 to Dyn11 or YNd11 to Dyn1 this vector group in Transmission line

Why we use mostly YNd1 to Dyn11 or YNd11 to Dyn1 in Transmission line
here i have show with phase angle clearly the reason begin this.

[@supremesoul1835]

nice one brother. so much appreciate your effort to make us enlighten.👌🏿

thank you and most welcome

[@muhammadismail630]

I really appreciate your teaching method and I am watching your videos everyday . Wish you best health.

[@baranitech1026]

thank you very much

[@petarsimic2303]

Thanks for video! Can you cover all transmision line protection and automation functions in detail after you finish series with transformer protection lectures?

[@yuvanraj9966]

Thank you sir your video very like fully that

[@baranitech1026]

your most welcome

[@user-ur2mc2bo7e]

Hi thanks for the video ,but I didn’t get why we need phase displacement. If we transmit it with zero degrees and distribute it with zero degrees what will happen?

[@baranitech1026]

when we make DY transformer it will naturally make phase displacement.

[@tufailalam6438]

Thank you for this video... Please upload more videos like this... Please make video on distance relay

[@wongsabarchannel1335]

When Step up transformer (11/500kV) is YNd1, then Unit Aux Transformer (11/6.3kV) is Dyn11, the Distribution Transformer (6.3/0.4 kV) Should use Dy11 or Dyn5 or we can used both, what is the Reason?
Above is for in SLD.

[@baranitech1026]

it will compensated the angle different

[@wongsabarchannel1335]

@@baranitech1026 It still not answer my question.. Can you check my question?

[@baranitech1026]

@@wongsabarchannel1335 you can use DYn11 or DYn5 . over there. both have same value only.

[@wongsabarchannel1335]

@@baranitech1026 What different when use Dyn5 and Dyn11? The advantage maybe

[@rjshtk]

@@wongsabarchannel1335 The Dyn5 trafo can be used to supply the excitation system with incoming ac that gets converted and controlled by thyristors. The harmonics produced in the exxcitation circuit due to the semi con devices is prevented from reflecting on the upstream CTs by using the Dyn5 type transformer. The Dy11 is used for normal station auxiliary loads.

[@rukmagoud]

There is a mistake in drawing . You are showing Ynd11 from generator. Generator is star connected and it is connected to step up transformer with vector group Ynd11. Here Y is always high voltage side. But in drawing you are showing in reverse way. Please check

[@baranitech1026]

this is ref. schematic diagram from site

Thkz for the information

Always welcome

This is the most wanted explanation 💪🙄🌎🌏🐸😲🤔

thank you

Good video.

Thanks, and welcome.

[@joaquinsebastian9209]

Hi does it really requires to bond Neutral and Earth in the Secondary for Dyn11 Transformer?

[@baranitech1026]

Its depends on which application your going to use.

[@arifmehmud5677]

sir which software used for making this video????

[@baranitech1026]

i use PPT

[@DebjitDas93]

What will happen if the phase shifts to 60 deg in a combination?

[@Nikhilkumarsah-vk5ti]

Very Well Xplained!!! can you Have the video over other

[@baranitech1026]

i will try to make for other also.

[@jaynandan9937]

Sir can I connect parallel of two transformer having vector group ynd11 or ynd1

[@SunnySingh-ei3rp]

Sir thank u nice explanation.
There's can be many transformer in between generator transformer and distribution system so how this phase matching helpless.

[@rjshtk]

All those in between transformers will be YNyn0 type. So these will just carry forward whatever phase angle from the Generator Transformer side to the Distribution Transformer.

[@surendrakverma555]

Good

[@baranitech1026]

thank you

[@rjshtk]

at 5:30 of the video, you have shown the Generator stator side of GT as Star. That would be wrong. It has to be delta!

[@baranitech1026]

if you use GT as Delta then distribution should be low voltage. in this video i have show for HV

[@tugsmandalpurewdorj1815]

Thanks

[@akibkhan2274]

why it is needed?

[@baranitech1026]

yes taking lv side star and to avoid 3th harmonic on HV

[@sagarraj.trajtt9634]

Pls upload TTR test.....

[@baranitech1026]

i will make soon
