เข้าร่วมเมื่อ 17 ส.ค. 2019
Hi friends this channel is all about sharing of my experience in the field of electrical engineering and protection system. Different types of relays used in sub station for different protection purpose. Each of relay has specific part on protection. I am trying to share my knowledge and this is why I choose this platforms. Please go through the videos uploaded in this channel. Your valuable comments are welcome.

Thanks for your excellent explanation
I'm glad you found it helpful.
My powers suppy when i plug in mu gpu
sir please make s1 s2 s3 ct wiring in vcb busbar in hindi language
I can try to make a video on CT wiring in VCB busbar in Hindi language in the future.
Sir kindly show a real tcs with connection details
nice vedio sir.Thank u
very useful to me.thank u sir.And it seems the relay will not pick up at the second part of the explanation that is during internal fault.Pl correct me if my understanding is wrong.
Wow, 29000 amp short circuit current at 33 kilovolts that's a big explosion, no safe PPE exists for something that bad.
Explained clearly.
Im first😂
What is overload ratio time in numerical relay
Stabilizing resistor should connected with S1 right ?? Here connected in s2
It is voltage operated relay, since Rs is connected in series. So what is difference if RS is connected with S1 or S2?
How to test Neutral displacement relay in NCT Cap bank?
Thankyou sir, keep it up
Thanks
Sir PT CVT ka bhi please
excellent explanation
Many thanks for your video, it was really good.
Very insightful 👍
Sir why ref is provided for star side only.
Tq
Good explanation, please upload more such videos👏🏻
I am glad you found it helpful. More videos are coming soon.
Super
No one but I respect for this type of most valuable information 😊. I also work at 400 KV , 500 MVA Transformer.
Thank you for your appreciation.
Thanks sir this video
Most welcome
Thanks for the video🤝
Thank you very much for the explanation you just help me, im in south africa 🇿🇦.

Thank You
Sir, if a feeder acts as an incomer as well as outgoing feeder as per load requirement, then how distance protection works for both the cases??
You can go through the plyalist videos for Distance Relay th-cam.com/play/PLawO3DDAIgHFw47LNXQ3mvKLjIU6m5Wbt.html&si=6CJH2w5v7tN4_X81
Nice explanation bro 👍
Thanks!
