Sir I'm newly joined in this protection field, and I have very low knowleg in its. but, yours lecture vedios is very very useful for me sir, thank you soo much sir. Congrats to u sir for this great work
In case 4 you didnt mention about zone 3 coverage and directly discussing about reverse protection zone 4...can you please explain with zone 3 along with zone 4..
Very useful video sir.... please clear one more doubt....by which medium on distance relay sends carrier signal to another substation.... kindly explain in detail
Sir, in zone-2 the setting of impedance will be around 100% line +20-50 % of remote end right. What will we consider in remote end i.e., transformer impedance or line impedance in remote side?
@@baranitech thanks for your reply.. But sir i have seen two distance relays are used to protect a signal transmission line at one end of transmission line (sending end or receiving end)
@@tufailalam6438 One relay is chosen as Main1 and the other relay is taken as Main2. Both provide simultaneous protection of the line. It is ususal for configuring main 1 with distance and main 2 with backup ocef protection only, or both relays with all protection activated.

you are making great educational videos, how come this channel isn't more popular?? BEST RELAY PROTECTION CHANNEL ON YT. thank you very much sir.
Thank you very much

Thanks and welcome
It is very helpful for all electrical engineer. I'm very interested to learn about practical based learning.. thanks to you
I will try make some practical video also 👍
Very detailed explanation in simple words.... Thanks for sharing your knowledge...
thank you
Very informative video 🙏🙏🙏🙏
thank you and welcome
good explanation sir...
Thanks and welcome
Thanks for the video.
welcome
Thank you sir for sharing ur knowledge
Nice
welcome
Well explained.Thanks
Welcome
Nicely explained...
you most welcome
In case 4 you didnt mention about zone 3 coverage and directly discussing about reverse protection zone 4...can you please explain with zone 3 along with zone 4..
i will make for you
Great boss,
We need weak end feed knowledge pls make tutorial for us
Very useful video sir.... please clear one more doubt....by which medium on distance relay sends carrier signal to another substation.... kindly explain in detail
yes i will make one video for you.
Thanks a lot. It helped me.
You're welcome!
Thank you sir for valuable msg. Pls upload setting calculations also.
It is very good info.
Please explain by taking the example line distance and explain it so that we get it easily pl it's my request
thank you, very useful
Glad to hear that!
Hi sir. Your videos are awesome. I need your help in configuring RET615
yes i will make
yes thanks you
welcome

line impedance
kindly uload about distance and line differential interblocking video and additional power swing, sotf, vt fuse fail auto resclose

Good
Thanks
Nice video sir...Can u explain the DUTT, PUTT & POTT scheme in Distance relay???
yes i will for you. right now i am making bus bar protection video so after that i will make for you.
Thanks
welcome
Zone 4 timing is not greater than zone 3 timing.. as per CEA zone 3 time delay is 800-1000 ms and for zone 4 -500ms.
yes i have made mistake thank you very much
Thank you for this informative video.
Sir what about zone -4
rev zone normally 25%
இது emgineering subjevt ah
yes
Hi can anyone please let me know that REF615J can be used for distance protection
REF615 cannot use for distance
why do we use two distance relays to protect a signal transmission line

@@rajeshtk1246 ok.. Now please tell me what protection futures are configured in main-1 and main-2 relays

why do we need 3 zone protection of transmission lines??
For we use it as backup for protection

Please improve the speech quality and pronunciation
I WILL TRY TO IMPROVE
you can't explain is clearly.
i will try to explain in clearly
Good
Thank you
