- Bus bar protection is very much essential for a stable operation of power system. Since bus bar is the node of KCL and connects all the sources and loads together so proper isolation of faults for bus bar is essential for sable power system operation.

Sir, your channel should have millions of subscribers. Thanks
But my channel doesn't have that..... but thanks for your support. Please share my videos
You explain thing so easily, thank you.
Keep sharing your knowledge.
Thank you Sir. Your method of teaching is very good.
Boss.. Your method of briefing is very Excellent.. Also appreciate your Knowledge and Efforts to help needfuls.. 👍👌...
Your explanation is great ... Thank you very much
Nicely explained. Thank you very much sir.
Sir u hav a very good knowledge. Thanks for sharing with us.
Wowww. Thank you so much.
Beautifully explained
Great video. Thanks
the explanation is very clear
thank you for your efforts
explained beautifullly
Very good. Thanks 🙏🙏🙏🙏🙏🙏
Thank u for ur job👍👍👍
I love your videos.
In brief, so better discussed, sir
It's beneficial for professionals as well
Crystal clear!
Very good video sir
VERY NICE SIR SEEMS YOU ARE WELL EXPERIENCED IN INDUSTRIAL APPLICATIONS (THOUGH LOOK STILL YOUNG ) . AND SURELY A GRADUATE FROM VERY REPUTED ENG COLLEGE ..
excellent explanation
Thank you very much
EXCELLENT
Hi your all videos nice and useful. I request 4 u relay testing videos. Makes....
Best💯💯
Good thank you
Thanks, plz make more videos about protection relay
Realy super
Thanku..sir
Also explain about the calculations of using protection
Sir..Please make videos on switchgear protection settings...
Thanks for this pretty & easy explanations!
Pls explain the pilot wire protection scheme for two distance breakers.
Sir Please do a video regarding partial busbar protection
Sir, your video is very important to us.. Very easily we can understand... Next time Please make a video on fast bus transfer scheme....
i will release a video on switchyard bus transfer shortly, after that i will make video for fast bus transfer
@@electricaltechnologyandind5335 thanx sir..
Helllo sir, here short circuit current rating which you have mentioned is what type of short circuit? Single phase to ground or three phase?
Overcurrent and Earth fault setting for busbar protection, explain with calculations sir.
Please explain bus differential protection scheme for one and half breaker system
Respected sir
Whether there are different time for different fault current or generally 1 sec or 0. 5sec for all fault current. How to select time for fault current i.e more current means less time. Withregards
Very good explanation
Pls make video on 1) BUSBAR Main zone 2 ) BUSBAR CHEK ZONE
And pls give function of Relay 50-2 and 50-2Z
Very nice video. Sir I have a question. Is the polarity of CT always such that P1 and S1 have same polarity. I checked the name plate of CT in switchyard it has no polarity mentioned like dot sign n all. So should I consider that P1 and S1 have same polarity?
yes... dot sign is a text book concept. it is not employed in practical use. but p1,s1 has same polarity. the reason which i feel is that you can not make cable termination schedule with dot convention. but you can make cable schedule if p1, s1 is marked. suppose the cable shall be connected between s1 of ct 1 to terminal 1 of Relay 1, like that....
IF YOU CAN MAKE A VIDEO APPLICATION OF LOCKOUT RELAY EMPLOYED IN A VCB ( IF POSSIBLE SCHNEIDER ELECTRIC VCB SWITCHING CIRCUIT . I HAVE SEEN MANY VIDEO BUT THEY ARE NOT EXPLAINING CLEAR .
Please do video on different types of starters and how we selected that starter? like DOL, START- DELTA,SOFTSTARTER.....BREFLY.......
dol and star delta starter is already available on this channel
hown the 51 and 51n residually connected kindly explain the connection and how it works
Residually connected means?
Sir, please share videos related to generator excitation & it's protections.
Thanks
give me some time, i have few videos on queue. so it may take some time...
@@electricaltechnologyandind5335 ok, thanks sir
Please, can you tell me which CT ratio will be applied for all three protection schemes according to your video? Thanking you and expect your valuable reply !
for over current and earth fault the ct ratio shall be the maximum possible incomer currentx1.2:1A or 5 A
same ratio for for differential ct.
for outgoing differential ct the ratio shall be based on the outgoing current*1.2:1 or 5
modern day differential relay does not require any ratio correction.
@@electricaltechnologyandind5335 thanks a lot !
At 14: 15 approx,u said that, if we maintain the ratio .......ratio of what ?
Tq sir kya Hindi video provided Kar sakte ho
What is 51 in there...???
