I was always intrigued by why there are all those odd contraptions on electric utility poles. This explains it all and breaks down the concepts. I already was familiar with step down transformers and grounders but all the other equipment was a mystery to me.
great video. i would love to do line work someday. i always knew what insulator, transformers, and cutouts were but i never had a complete understanding of lightning arresters.now i do. cool
There was a story in the local news about people stealing electricity or wires I cant remember and they got arrested. Maybe our local law enforcement should get in touch. Thanks again
I familiared with Lightning Arrestor at our Kaithal(400/220Kv),Power Grid Corporation of India Limited(C/O Alstom-GE T&D India Ltd.,GE-Energy Connections) site. I was an EHS Officer(Teamlease Ltd.,Bangalore).
Also two lightning arrestors within a second becomes super hot when operating for that millisecond and if any cracks or erosion was to form outside the insulation it will explode aka a bad lightning arrestor
My boss had me wearout 3 hacksaw blades trying to cut thru a 10kv arrestor longways. I gave up cutting thru the fins and only about 1/16th of the mov. That sucker is built to last!😮
Actually it isn't. A close, hard strike will blow one to bits! Seen it happen on my property. Was picking up pieces in a 30ft radius around the pole with the transformer on it.
EXPLAINED WELL ABOUT THE MATERIAL FILLED IN THE L.A. WHAT IS THE SIMPLEST L.A. FOR A 3PHASE 4 WIRE 5 KVA POWER COMING TO A HOUSE TO BE INSTALLED AT THE LAST POLE & THE COST?. THANKS.
In case of a double steel tubular pole mounted 3 phase distribution transformer is it important to provide an insulation/insulator between LA and metal channel on which LA is installed and why?
Can high dog with no lightning cause a lightning arrestor to cut power? Guy on the ground said guy on the pole was fixing the arrestor at 3am when I got home. After listening to this, and what I could see through the fog in the dark, I dont think this would be an issue to come fix three hours into new years day unless the fuse blew, or the transformer was picking up extra charge from the arrestor malfunctioning? Maybe I'm thinking this wrong, but foggy high humidity conditions could cause static discharge that might warrant this? Would love any help from someone that knows this trade as I am below a layman.
Wow this the 1st time in my 35yrs just learned that those thing on the electrical post are arrester tho small but theyre functions are so big..now my question is can we put this arrester in our open field like school ground because we have already casualties of school children killed by lightning when they were caught up taking shelter on the shade trees when rain and thunder starts they had no time to run to our school building.
OK dear it's very usefull to learing. thank you for your Wonderful explanation.....what is my doublt is in ship we called surge suppersser we using in high voltage generator...do you have any idea about where it locate in generator Excatly and how we identify weither it is good or faulty..
What if I will install MOV every electrical socket in my house considering one outlet with extension cord supplying around 3 different applicances. Thank you.
thanks a lot.. i am elect. engineer and in fact we do not utilize surge arresters except for 132-KV power line... i do not work for power company but i think due to non lightning area we live in, we never use SAs in less than 132000 volts... is that correct?
Thanks great explanation. Just one question, what is the lightning's route? Is it through the lightning arrester? And there are also lightning arresters inside switchgear so what's the concept there?
Thermal imaging is the best way to tell if an arrester is not failing. If it is not failing it is working. See www.arresterworks.com/arresterfacts/pdf_files/infrared_thermometer_as_arrester_tester.pdf
Greetings Roland, An insulator is always an insulator. An Arrester is like an insulator until a surge comes along and then it turns into a conductor. It insulates most of the time. I like to call an arrester a smart insulator but niether the arrester or insulator manufacturers would like that.
Lightning, you’re under arrest!
Best video to explain Surge Arresters (or Lightning Arresters) basic principles ! Congrats Jon
@@metarresters thank you

Ur way of explaining is sooo smooth.. I loved it.. It's just keep refreshing my mind... And made me easy to understand.. Ty so much..
Excellently explained. Soothing voice and I appreciate the bird at the end.
great video. i would love to do line work someday. i always knew what insulator, transformers, and cutouts were but i never had a complete understanding of lightning arresters.now i do. cool
Nice concise explanation.
great video, very clear and concise explaining of the concepts.
This video described the subject in a neat order and smart steps. Really helpful, thanks.
There was a story in the local news about people stealing electricity or wires I cant remember and they got arrested. Maybe our local law enforcement should get in touch. Thanks again
thanks for making such informative videos..it is a great help in my study and i am sure it is helping other in their studies too
So it’s basically a home surge protector on steroids.

Thanks for your very good explanation.
Hope we are expecting more knowledge from you experience.
Thank you for the valuable information
Excellent explanation👌👌👌
Thanks it really made me understand alot about the lightening arrester
God bless really a great video... i was always confused about surge n lighting arrestor.
Great invention. Just outstanding idea.
Also two lightning arrestors within a second becomes super hot when operating for that millisecond and if any cracks or erosion was to form outside the insulation it will explode aka a bad lightning arrestor
Interesting way of diverting the charge to ground, many pathways from top to bottom of the insulator.
This was just great sir!! helped a lot 😃
simple and wonderful explanation 😊
nice subtle background music, kept the pacing apt
Great presentation. Nice
Thank you, it was very helpful.
Superb clear educational video.
Good explanation.. thanks Sir.
Great work😊
Simple and Clear. Thank You.
Thanx for the explanation
Great video. it answer all my questions. Thanks
excellent explanation ...................
Thanks and more power.

And what kind of hacksaw did that lightning strike use? Certainly not the hardware store variety?🫣😝
Probably some moisture inside that turned to steam when the bolt hit and expanded with force.@@lmsubman243

Thank you i need to give a presentation on Thursday. I hope i can explain it well please pray for me.
How did it go
@Lt.Dan it went well. Thank you for asking
voice is so much close to sir Tom Hanks!! thankyou sir for the explanation.
Beautiful explanation
Really helpful, thanks 🤝🏻
excellent graphic representation. thanks.
Very good informative video
Thank you sir Jonthan! :)

Thanks about info light arrester!
good video. Pike Engineering extends its greetings.
great content, thank u for sharing

Thank you for the is video.. 😊
who loved his voice put a like
This explains why my transformer doesn't go kaput in a lightning storm, but the grid still goes out sometimes.
How can SPD protect my device when connected in circuit when power is off sometimes during rainny seasons and lightinig takes? T place.
how is selection of surge arrestor is done based on current rating in Low volatge application.?What is Type 1, Type 2, etc,...
Well done. Thank you.
very good explanation
Thanks. That video is understandable

thanks a lot teacher , ♥♥♥
Nice work!
So what are the pros and cons of this type of arrestor versus a gap type arrestor?
This answers my questions
#thank you sir
This type of arrestor was used on my tower crane
What if I will install MOV every electrical socket in my house considering one outlet with extension cord supplying around 3 different applicances. Thank you.
I've finally found Thor's weakness.
but what is the point of arresting the lightning if no charges are being brought?
Thanks
thanks a lot.. i am elect. engineer and in fact we do not utilize surge arresters except for 132-KV power line...
i do not work for power company but i think due to non lightning area we live in, we never use SAs in less than 132000 volts...
is that correct?
Thanks great explanation. Just one question, what is the lightning's route? Is it through the lightning arrester? And there are also lightning arresters inside switchgear so what's the concept there?
Yes, where else would it be?
How to test them to know it’s in good condition?

Thank You
Great video..
thank you
thanks this video
Thank you
tnx..for the information sir..its very helpful..
Nice & easy
What is the current path when lightening is occurred on Lightening arrester
good explanation
How many strikes are these good for?
amazing . thanks
Im watching this cause this video is in my online class😂
This was a perfect video
nice explain. thanks
What's the difference betwerrn an arrester and an insulator, arent they the same thing?

A great question and a brilliant reply
awesome explination 😘😘😘
which protection is given by lightning arrester
direct lightning protection or indirect lightning protection or both?
Both
Do we keep this lightning arrester in top of home
it's very useful for me thank you ALSTOM...
thnk u ..so much
Thank you soo much sir😊😊
Thanks that means mov switching is far far faster than lightning understood
Insulators and lighting arrester are same sir
nice video
thaks , its great.
