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
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?
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
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
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.
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.
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 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).
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?
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
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..
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?
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.
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!
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..
Best video to explain Surge Arresters (or Lightning Arresters) basic principles ! Congrats Jon
@@metarresters thank you
Excellently explained. Soothing voice and I appreciate the bird at the end.

great video, very clear and concise explaining of the concepts.
Nice concise explanation.
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
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
This video described the subject in a neat order and smart steps. Really helpful, thanks.
Thank you for the valuable information
Excellent explanation👌👌👌
Thanks it really made me understand alot about the lightening arrester
Thanks for your very good explanation.
Hope we are expecting more knowledge from you experience.

God bless really a great video... i was always confused about surge n lighting arrestor.
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

Great invention. Just outstanding idea.
This was just great sir!! helped a lot 😃

Short & informative.
simple and wonderful explanation 😊
how is selection of surge arrestor is done based on current rating in Low volatge application.?What is Type 1, Type 2, etc,...
Superb clear educational video.
Great presentation. Nice
How can SPD protect my device when connected in circuit when power is off sometimes during rainny seasons and lightinig takes? T place.
Interesting way of diverting the charge to ground, many pathways from top to bottom of the insulator.
Good explanation.. thanks Sir.
So what are the pros and cons of this type of arrestor versus a gap type arrestor?
Great work😊
Thank you, it was very helpful.
Really helpful, thanks 🤝🏻
Great video. it answer all my questions. Thanks

nice subtle background music, kept the pacing apt
excellent explanation ...................
but what is the point of arresting the lightning if no charges are being brought?
What is the current path when lightening is occurred on Lightening arrester
How many strikes are these good for?
Very good informative video
Beautiful explanation
Thanx for the explanation
Simple and Clear. Thank You.

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?
Can i get the background music file?
Thank you for the is video.. 😊
Excellent work
Thank you this was really helpful
Thanks and more power.
Thank you sir Jonthan! :)
Do we keep this lightning arrester in top of home
So it’s basically a home surge protector on steroids.
great content, thank u for sharing
thanks a lot teacher , ♥♥♥
Super explanation
excellent graphic representation. thanks.
How to test them to know it’s in good condition?

good video. Pike Engineering extends its greetings.
Nice work!
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
very good explanation
Thanks about info light arrester!
which protection is given by lightning arrester
direct lightning protection or indirect lightning protection or both?
Both
How about dry type transformer 440 to 220? Where do I install arrester?
If the transformer is exposed to surges, then put the arrester close to the transformer on the side of exposure.
What is the connection?
Because I tried put the ground bar and connected to the neutral. I think something wrong.
Great video!! Thank you for posting.
How much receving distance
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?
Whats is difference between surge arrestor and surge counter ?
any body help will help me
SA is the equipment that use to protect the transformer, SC is the material that use to count the number of lighting faults and the leakage current
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!😮

@@JP-rf7px
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
This answers my questions
#thank you sir
voice is so much close to sir Tom Hanks!! thankyou sir for the explanation.
From mine how does VCB works
Thanks. That video is understandable
Well done. Thank you.
What's the difference betwerrn an arrester and an insulator, arent they the same thing?
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.
A great question and a brilliant reply
Great video..
This type of arrestor was used on my tower crane
awesome explination 😘😘😘
I've finally found Thor's weakness.
This explains why my transformer doesn't go kaput in a lightning storm, but the grid still goes out sometimes.
Thank you soo much sir😊😊
Good video, thank you!

good explanation
how to instal lightning arister
This was a perfect video
thanks this video
Insulators and lighting arrester are same sir
nice explain. thanks
it's very useful for me thank you ALSTOM...
tnx..for the information sir..its very helpful..
Nice & easy
do post calculation video abt it ....
nice video
who loved his voice put a like
amazing . thanks
So it’s a diode for AC system
