This was a great video, very informative and concise. I was able to understand almost everything but I agree with the other commenter that it could be helpful to provide captions or subtitles.
Why are surge arrestors installed just before transformer’s terminal (6:15)? Can they be installed at the distance of, for example, 100 meters from transformers?
Great video, but I have a question that I cannot get a good answer for from any Electrical Engineer that I have asked. I work for a power generation company and in some of our older substations we have surge arrestors rated at 24kV on a 34.5kV system and we all know that the voltage on a 34.5kV phase to ground measurement is around 20kV so that makes the peak voltage at around 28kV, so is the surge arrestor actually shunting the excess voltage (approximately 4kV) to ground 60 times every second ? In our newer substations those surge arrestors are rated at 29kV which alleviates this problem. Can you please help me understand how the surge arrestors are not wearing out very rapidly?
I have one doubt tho .. Suppose a lightning strike of say, a million volts occurs, you seem to mention that this will pass through the surge arrestor. But what prevents the lightning from already passing and damaging through the other equipment because these will have lesser resistance than the surge arrestor?
This is where the protection systems will kick in, where the CTs and PTs are transducers and send signals to circuit breakers and switchgear that react very fast to cut off power immediately. That is why in power systems we have protection zones.
The lightning takes the least path of resistance to get to ground. The surge arresters are designed and configured to be the least path to ground so that lightning will go to ground through the surge arresters instead of to ground through the expensive equipment.
Hi thankyou for watching our videos Software used: 1. Blender and Maya for 3d Model 2. After effect for Compositing & AV Editing 3. Some times Photoshop for Photo Editing
The video is great, i understand it so much, but if you could make your voice clear i.e better mic maybe, thaen it would be better, anyways thankyou so muchhh
In my book of diploma... According to book a capacitor in parallel or inductor in series is connected in line to reduce or absorb high frequency waves to protect system against high frequency waves produced by lightning or switching... This whole arrangement is called surge absorber... The most common type pf surge absorber is ferranti surge absorber
It is hard to understand considering your accent, which I have no problem with as I am looking to your page. I really would like to listen to you though.

Or use the robot voice
I would like to thank you for this wonderful presentation. Great job.
Great video for non-electrical engineers. Thank you
Great video and very helpful. I appreciate you posting this.
U have explained a small topic in the best way 🙏🙏👍
Thank you...
Sharmaji, keep it up, you are awesome.
Hi, may I ask what software did you use for the 3D modeling of the substation? Thank you
Thank youuu so much sir , this video helped me a lot l was finding the topic hard to understand but not l understand.
Thank you mr. Sharma that was very helpful

good explanation. I have one question what is the program that you use in explain?
Informative video & Great Work bro 👌. Kindly post a video related Surge arrestor sizing & Selection.

Awesome ❤️
Good information
thanks for your video.
Which software did you use to do this 3d modelling of substation??
Very Good
Great video. Your explanation is excellent 👌. Keep it up 👏.
Just one question. What is the name of the software you used to design that power system?
By the look of it, I guess it's Autodesk Maya...
How does it's resistance decreases?
The purpose of the rings is to control the electric field distribution to prevent flashovers, right?
Good explanation

Hey, could you have subtitles on your videos?
i think you have good content but hard to understand what you say :)
Thx
What software was used to model the system in the video?
Hi thankyou for watching our videos

Sir please provide video on different types of circuit breaker and there working..

The video is great, i understand it so much, but if you could make your voice clear i.e better mic maybe, thaen it would be better, anyways thankyou so muchhh
Sir why did you stop making video🥺
Nice video, but please add subtitle for those who may find it difficult to understand your accent. Thanks.
Surface area of insulator increase and heat dissipate high
Are surge arrestor and surge absorber same?
Might be Yes, where you heard about this term "Surge absorber"
In my book of diploma...
According to book a capacitor in parallel or inductor in series is connected in line to reduce or absorb high frequency waves to protect system against high frequency waves produced by lightning or switching...
This whole arrangement is called surge absorber...
The most common type pf surge absorber is ferranti surge absorber
Sir you uploaded a video on fb about my query that why circuit breaker in bus coupler...
But there is no voice in that video
You mean shocks absorber?
It is hard to understand considering your accent, which I have no problem with as I am looking to your page. I really would like to listen to you though.
Sorry about that
The rings keep snakes off
Wtf...
terrible accent
really helpful video
