As an equipment operator that's comes close to many wires regularly, we are trained to do what's referred to the Hydro shuffle when requiring to exit an energized machinery. Bunny hopping away leaves probability of one foot leaving the ground at a different time than the other. You don't want to be the electrical short between the rings of voltage radiating outward from a live wire contact.
Interesting. A lot of our power failures here are caused by shorts on the poles in winter: dried road salt gets flung up onto the wooden poles by traffic, then a light rain wets it down, so you have wet, salty (very conductive) wood. You can hear the electricity sizzling through it. Eventually one (or more) poles becomes so conductive that it heats up and catches fire, then the wires come down.
Tough crowd. Must be hard giving presentations to young people as everyone is too busy being self-conscious to take part. Me?

Thank you for the demonstration, I've seen some crazy things happen with electrical power lines. One time a person from my high school decided to toss his old pair of shoes up on the line, he contacted 2 wires which then caused the square block of wires to start to fry and melt the casings. Luckily everyone had cellphones and called the fire department and they followed the sparking flaming line, not sure how it stopped but it did eventually. They couldn't do anything until the electricity company cut off the power. Another time a huge small tree sized tree branch fell onto the power lines outside the house and it was hanging there, had to call electrical company which put me through to forestry which then removed the branch. I was amazed that the line was able to hold so much weight... well before the forestry people came to remove it, some numb skull idiots decided it was safe to walk right next to the fallen down branch which was pretty damn close to the side walk. Luckily the line never broke, split or cracked to let a current through or those people would be literally toasted inside.
The reason they can hold so much weight is mainly for the fact that between poles they are sagging a bit by default, it would otherwise require much more force between each pole to hold it up, next to the risk of a pole toppling if it would snap somewhere. (And there's also the thing of the cables being made up of tiny copper wires wound together into bigger cables, bundled together to form the bigger cable, they are able to carry much more weight than 1 solid cable.)
That's a neat demo. Our site requires us to use a tick tester before making contact with recently energized parts. You should add the tick tester to your demo.

By him saying the homeowner "hooking it up wrong" in regards to the generator, he means hooking it up correctly but not interlocking the service main breaker where it's open when using a properly installed generator connection.
Truth is most people who don't know anything at all just plug the generator in at a plug that happens to be connected to the circuits they wanna run. All the copper connected to that circuit becomes a telephone line. I'm not saying it could happen nowdays but would love to see a Honda 1000 el cheapo light up a transformer. If it don't go "BOOM" then it will just be open and take longer to fix
I was in Oklahoma staying in a rv, with my boss his dad's place, power went out uncle went out to hook up the converted irrigation motor to a genny. I'm vacuuming the floor an the power goes out couple minutes later comes back on, I went back to vacing shit started smoking. I finished quickly went to look out the garage. Seen my boss dad sprinting across the lot shuts off the genny. Well 2 computers 3 deep freezers an one vacuum. Where taking to soon that day. I assume its because of what this man explained to us.
I have been in the HVAC, Plumbing, Electrical, Building Operation and Maintenance industry since 1976. I was fortunate to have been through Arc - Fault / Arc - Flash training. I thought that your demonstration was very well presented. You may want to mention to tradesmen about transient voltages that may be carried along with the power lines and that their testing equipment should be Category III / IV rated and anyone who works directly with electrical infrastructure should be wearing NFPA70E clothing.

We used to have a transformer in our backyard that constantly tripped. The power company would come out and use a pole to flip a metal rectangle "switch" upward and we'd have power again, took them hours to come out and 45 seconds to "fix" it. They refused to replace it even though we lost power 3-5 times a month during the summer. Finally got to the point one of the immediate neighbors got a long pole and it stayed on the ground under the light pole so one of us could flip it back up each time, reducing the outage inconvenience to 10min or so. Finally took 11 households banding together, one of which was a lawyer, to get the power company to replace the transformer. We lived there 3yrs after and never had another power outage. Not sure any of us would have done that if we had watched this video first! I had no clue those wires were live and not insulated, crazy!
I used to work for the local cable company, we had a lot of aerials in our community so I had to carry an extension ladder down ally's and then sling it up on the mid span, usually the cable company has the lowest span for fiber and coax. but when I was on top of the ladder at the coax/fiber I was very very aware of the humming wires above my head. that shit was scary when it was wet outside.
Every one needs to see this! Utility locator here the general public needs to get a little more info on what makes their life's easy to keep them selfs safe and report issues rather than hide them and fear a financial penalty and risk the entire communities health sadly see it every week
It's not free of charge. The utility company will pad it into their cost of power. Someone is paying for it. It's neat that it is free of EXTRA charge.
My dad was a T&D lineman in St. Louis for 23 years. When I was little, we could set our clocks to the phone ringing as soon as the sleet started. 5 below to 105, rain, sleet, sun. And he started doing it right after he got back from kicking chinese ass in Korea for 2 years. Here's to these under-appreciated heroes. He did it to allow me to go to school and become a lawyer. I think I was more proud of him than he was of me.
I think another super important thing is diving into the specifics as to how electricity works and why. And how. And where. the whole 9. Having a better understanding of how things work and what not to do I feel is definitely worth explaining more indepth and most definitely not a waste of time. Electricity is a mysterious thing. And it's gonna do what it wants if you let it and can be extremely complicated.
Joe Banfield: Im going to go over some of the Do's & Dont's now #1 DO stay away from power lines I repeat "DO stay away from power lines" #2 Don't go near power lines Thank you everyone for coming out.
Excellent vid. Not sure who the audience was or who it's for but as a fork lift mechanic I enjoyed listening to the vid and in no way did I feel as if the instructor was putting those listening down, he was telling things the way they are.
When I need to go into the UPS room at work (not an electrician by the way, we sometimes place soaked camerabags there because the room is kept at a low humidity and is reasonably cold, so the things dry well there) I always make sure to be in and out as fast as possible. Not only does the humming of the whole distribution box and battery bank freak me out, I probably don't want to be there when a power outage happens, since the switches in the distribution box are probably springloaded and maybe also supplied with gas cannisters to quench arcs and as a result, it's probably stupidly loud.
Eleven year lineman, work for William Electric Shelby NC. Contract for Duke Power 7200 volts. Did underground and overhead and even set the meter, we did it all from one pole job to eight or twenty pole whatever it took to do the job.
I don't know if they still do it or not, but around here the power company had a large scale model of your typical neighborhood they would take to the schools and put on a demonstration. Little neon lights shaped like people to demonstrate what would happen if you hit a power line, plenty of burned hot dogs, and some basic demonstrations of PPE. The guy always said the only thing he really trusted with his life were his gloves because he could blow them up and see if there was a hole in them or not. The guy would put a hot dog is his glove and get it up against a line and nothing would happen then poke a hole in the glove, put a hot dog in it, and cook it through the pin hole. It was geared more towards younger people, but the message was pretty clear.
VERY nice demonstration and lecture ! Congratulations to your crew for a job well done. QUESTION: Have you ever seen a failure of a pole transformer in the distribution side of your business? If so, what caused it?
i live in an old subdivision with lots of trees and power lines above, this is good education with all the power lines i seen fell from trees and Storm, and didnt know u had to bunny hop out of the car!
That is the purpose of an ATS ( Automatic Transfer Switch ) when a customer buys and has an electrical company install the pad mounted generator. I personally have most experience with the Cummins generators and I have done a few of the Generac generators. When the house loses power the generator senses the lose of utility and switches the panel towards generator power, then once utility comes back the generator switches back in around 5 mins (depending on brand).
Microwave ovens do NOT cook from the inside out. The radio waves only penetrate about 0.4" (1 cm), so they only heat the outside. The heat from the outside conducts to the inside of the food.
They need this type of demonstration for my community here in Wv. The power lines here in some spots is no higher than 20ft and that in the mountains and spots that haven’t been upgraded. I know where a pole is near me with an open wire secondary on it that’s 12 foot above your head! Power company has been called and emailed multiple times but guess it won’t be fixed till there’s a fatality.
At the beginning of this video, I was just about to say, how stupid could somebody be to plug his generator into the mains. Then I remembered that a college of mine whom I considered to be quite knowledgeable about electricity complained to me that his generator kept tripping when he plugged it into a wall socket so that it would power the whole house. Even though that is not quite how things should be done I asked him if he turned off his mains idolator before he connected the generator, to which he answered, he hadn't. I explained to him that his little 5KVA generator was trying to power everything on the grid outside the transformer or sub station that had tripped and how to rectify it, hopefully before electrocuting a few electricians.
@@Fatvod just turn off your main 100, 200 amp breaker and put a pin though the metal ring so no one can just flip it back on, wire your generator into a double pole 30 or 40 amp breaker i have a 40 amp as my generator puts out 220v 40 amps, after you turnoff the main start your generator, turn on your 30 amp breaker in the panel// good to go
@@arnoldromppai5395 Google or look on eBay for an Interlock Kit. It is a sliding piece of metal that won't let you have the main breaker and generator breaker turned on at the same time. That makes the set up you described idiot-proof. No matter how good we are, we all make mistakes and all have momentary lapses.
I just put in a Generac backup generator and a new service panel. The power company guy got up on a 24' ladder and pulled new wires to my new post by himself. That's one gutsy guy because the electrician putting the ATS in said he's never do that.
How did Rabbit holing from food history to a Hotep Jesus podcast take me here? Any ways, great vid, and ya, prolly the best explanation of power distribution I’ve seen
It's because it's easy to tap into them. Also this will give breathing room to the wires. And the main reason is to increase power capabilities. The main problem of insulation is that a fuckup in a line can cause all of the insulation to burn and melt. Imagine this in a larger scale
They are insulated, with air. Air is actually a pretty good insulator. The separation is different for different voltages though, as air has an insulating factor based on distance. I don't recall what it actually is at the moment, but something like a kV/cm, or somewhere around there. It does change a bit when an arc is struck, and their becomes ionized.
Going pole to pole seems like it would be very time consuming. Could we not generate a signal along the line at each pole, each with a different value, all added together at certain points. So then when you get a fault, you could just check the values and see which one is missing to pin point the fault location? There's gotta be a more efficient way than going pole to pole... Great video. I'm not a lineman, I'm IT, but I find this very interesting.
I felt the step potential once. We where standing barefoot on a Boulder on the edge of Lake George.. In the distance we saw lightning hit the lake. We could feel a little current.
Yep. It's basically what kills you, the difference, even if you might survive the intense heat and the shock of the intense sound pressure on your ears and being knocked down, it's usually the difference between either your two legs or (when people still think laying down is better than making yourself as small as possible while having your feet as close to each other as possible, your head and feet) that's the most dangerous. It's the same what shocks you when you touch the mains: you are at zero volt potential, and the mains isn't.
I live near Chattanooga, just south in Georgia. The top power line are 3 wires (3 phase). A storm blow a tree down and it broke all 4 power lines. The 3 phases and ground. The top power lines were laying on the road. People, with bare hands moved the high voltage power lines. They may have been dead, but something could have back feed. Some people are DANGEROUS. Another time a 2 phase line was on the ground very close to a trailer park with lots of little children. I called 911 and they said a downed line was not dangerous. sometimes 911 is not what it should be.
nice i helped make the plastics for power lines so they don't burn out their is like 5-6 other ground wires in the plastic that can not melt once it is set and made .
Great information - it can save your life. The instructor's pacing mannerism (back and forth) is described as a Tethered Elephant in the education field. He should conscientiously work on rectifying that distraction.
Mylar itself is not actually conductive, it’s an insulator. However, balloons aren’t just made of Mylar… they are also coated in a thin layer of aluminum, which is very conductive. The aluminum is why it’s reflective, otherwise it would be clear. Same with a bag of chips: it’s aluminized, and if it blows up against a power line, it’ll do the same thing as a balloon.

Me: I do.
By him saying the homeowner "hooking it up wrong" in regards to the generator, he means hooking it up correctly but not interlocking the service main breaker where it's open when using a properly installed generator connection.
...you mean Hookin the Honda up and forgetting that the main is still closed but don't matter because there is no voltage on top of it....yet...?
Truth is most people who don't know anything at all just plug the generator in at a plug that happens to be connected to the circuits they wanna run.
All the copper connected to that circuit becomes a telephone line.
I'm not saying it could happen nowdays but would love to see a Honda 1000 el cheapo light up a transformer. If it don't go "BOOM" then it will just be open and take longer to fix
Yeah I'd make my own tons of places sale all the right stuff to make up your own fuse box even the right size of wire or type aluminum or copper
I was in Oklahoma staying in a rv, with my boss his dad's place, power went out uncle went out to hook up the converted irrigation motor to a genny. I'm vacuuming the floor an the power goes out couple minutes later comes back on, I went back to vacing shit started smoking. I finished quickly went to look out the garage. Seen my boss dad sprinting across the lot shuts off the genny. Well 2 computers 3 deep freezers an one vacuum. Where taking to soon that day. I assume its because of what this man explained to us.
This was really cool to watch and VERY informative
Wow!!!! I did residential for quite some time and knew a little, but this is like must know stuff for every homeowner
I have been in the HVAC, Plumbing, Electrical, Building Operation and Maintenance industry since 1976. I was fortunate to have been through Arc - Fault / Arc - Flash training. I thought that your demonstration was very well presented. You may want to mention to tradesmen about transient voltages that may be carried along with the power lines and that their testing equipment should be Category III / IV rated and anyone who works directly with electrical infrastructure should be wearing NFPA70E clothing.

We used to have a transformer in our backyard that constantly tripped. The power company would come out and use a pole to flip a metal rectangle "switch" upward and we'd have power again, took them hours to come out and 45 seconds to "fix" it. They refused to replace it even though we lost power 3-5 times a month during the summer. Finally got to the point one of the immediate neighbors got a long pole and it stayed on the ground under the light pole so one of us could flip it back up each time, reducing the outage inconvenience to 10min or so. Finally took 11 households banding together, one of which was a lawyer, to get the power company to replace the transformer. We lived there 3yrs after and never had another power outage. Not sure any of us would have done that if we had watched this video first! I had no clue those wires were live and not insulated, crazy!
15:00 sounds like someone in the audience gagged at the fried “fingers” demonstration.
I used to work for the local cable company, we had a lot of aerials in our community so I had to carry an extension ladder down ally's and then sling it up on the mid span, usually the cable company has the lowest span for fiber and coax. but when I was on top of the ladder at the coax/fiber I was very very aware of the humming wires above my head. that shit was scary when it was wet outside.
Every one needs to see this! Utility locator here the general public needs to get a little more info on what makes their life's easy to keep them selfs safe and report issues rather than hide them and fear a financial penalty and risk the entire communities health sadly see it every week
It's pretty cool that you guys do this free of charge. It's very informative and could save a life.
Oh there’s definitely a - charge -…
Duh dum tsss.
I’ll show myself out.
@@falonhurst really dude? Oh you're fun a parties, aren't ya sport? Moron
It's not free of charge. The utility company will pad it into their cost of power. Someone is paying for it.
It's neat that it is free of EXTRA charge.
My dad was a T&D lineman in St. Louis for 23 years. When I was little, we could set our clocks to the phone ringing as soon as the sleet started. 5 below to 105, rain, sleet, sun. And he started doing it right after he got back from kicking chinese ass in Korea for 2 years. Here's to these under-appreciated heroes. He did it to allow me to go to school and become a lawyer. I think I was more proud of him than he was of me.
I think another super important thing is diving into the specifics as to how electricity works and why. And how. And where. the whole 9. Having a better understanding of how things work and what not to do I feel is definitely worth explaining more indepth and most definitely not a waste of time. Electricity is a mysterious thing. And it's gonna do what it wants if you let it and can be extremely complicated.
This was really good I learned a lot. They are doing this to save a life no charge... Salute
Joe Banfield: Im going to go over some of the Do's & Dont's now
#1 DO stay away from power lines I repeat "DO stay away from power lines"
#2 Don't go near power lines
Thank you everyone for coming out.
Excellent vid. Not sure who the audience was or who it's for but as a fork lift mechanic I enjoyed listening to the vid and in no way did I feel as if the instructor was putting those listening down, he was telling things the way they are.
As somebody about to become an apprentice electrician this was very informational
Good moment in video and the job of quality professional. Tank you very much.
That was totally time worthy, Lifesaving, and informative. Thanks...
Wow, I learned a lot. Tons of respect for lineman, coming froma 4th year ECE student. Bravo!
My little brother just started a linesman apprenticeship. How they can hear that hum of electricity and not **** their pants is quite impressive.
When I need to go into the UPS room at work (not an electrician by the way, we sometimes place soaked camerabags there because the room is kept at a low humidity and is reasonably cold, so the things dry well there) I always make sure to be in and out as fast as possible.
Not only does the humming of the whole distribution box and battery bank freak me out, I probably don't want to be there when a power outage happens, since the switches in the distribution box are probably springloaded and maybe also supplied with gas cannisters to quench arcs and as a result, it's probably stupidly loud.
This demo was awesome! Much appreciated!! Thanks for what you’re doing.
As an IBEW inside Journeyman wireman i can say i learned about step potential ratio and bunny hop.Thanks
Eleven year lineman, work for William Electric Shelby NC. Contract for Duke Power 7200 volts. Did underground and overhead and even set the meter, we did it all from one pole job to eight or twenty pole whatever it took to do the job.
I don't know if they still do it or not, but around here the power company had a large scale model of your typical neighborhood they would take to the schools and put on a demonstration. Little neon lights shaped like people to demonstrate what would happen if you hit a power line, plenty of burned hot dogs, and some basic demonstrations of PPE. The guy always said the only thing he really trusted with his life were his gloves because he could blow them up and see if there was a hole in them or not. The guy would put a hot dog is his glove and get it up against a line and nothing would happen then poke a hole in the glove, put a hot dog in it, and cook it through the pin hole. It was geared more towards younger people, but the message was pretty clear.
Woah, one minute im watching rap, then im learning about power lines. This is some electric stuff!
RAP? yeah that explains a lot
This demo could save so many.
VERY nice demonstration and lecture ! Congratulations to your crew for a job well done. QUESTION: Have you ever seen a failure of a pole transformer in the distribution side of your business? If so, what caused it?
Leaking oil, a broken lug, improper connections… the transformer itself is rather fool proof
Great video, appreciate what all linemen/women do, stay safe folks
i live in an old subdivision with lots of trees and power lines above, this is good education with all the power lines i seen fell from trees and Storm, and didnt know u had to bunny hop out of the car!
Great information.you guys are the best.
Been in the trade over fifty years. Love everything about it.
Wish I could learn from you, I love electric
@@LIL012185 there are a lot of good mechanics out there take knowledge from all of them. Thank you for complement
@@LIL012185 it's a great trade it's forever changing. Never boring
That is a great accomplishment!
I retired after 42 years. I'd do it all over again.
@@ghalgren I'm 70 retried open up another electrical business. Love the trade ( prices through the roof what was I thinking )
Great knowledge about electric power and safety....well done.
That is the purpose of an ATS ( Automatic Transfer Switch ) when a customer buys and has an electrical company install the pad mounted generator. I personally have most experience with the Cummins generators and I have done a few of the Generac generators. When the house loses power the generator senses the lose of utility and switches the panel towards generator power, then once utility comes back the generator switches back in around 5 mins (depending on brand).
Microwave ovens do NOT cook from the inside out. The radio waves only penetrate about 0.4" (1 cm), so they only heat the outside. The heat from the outside conducts to the inside of the food.
I really think this is a great thing to show people.thank you guys
Number one must have for linemen is a goatee!
Nice demo! do all the regional utilities do this?
They need this type of demonstration for my community here in Wv. The power lines here in some spots is no higher than 20ft and that in the mountains and spots that haven’t been upgraded. I know where a pole is near me with an open wire secondary on it that’s 12 foot above your head! Power company has been called and emailed multiple times but guess it won’t be fixed till there’s a fatality.
At the beginning of this video, I was just about to say, how stupid could somebody be to plug his generator into the mains. Then I remembered that a college of mine whom I considered to be quite knowledgeable about electricity complained to me that his generator kept tripping when he plugged it into a wall socket so that it would power the whole house. Even though that is not quite how things should be done I asked him if he turned off his mains idolator before he connected the generator, to which he answered, he hadn't. I explained to him that his little 5KVA generator was trying to power everything on the grid outside the transformer or sub station that had tripped and how to rectify it, hopefully before electrocuting a few electricians.
How exactly do you disable the mains isolator?
@@Fatvod Usually, it is a huge big fat switch in the DB. Turn it off.
I install them. it has 2 selections: Generator and Grid. You can only select 1 or the other, not both :D
@@Fatvod just turn off your main 100, 200 amp breaker and put a pin though the metal ring so no one can just flip it back on, wire your generator into a double pole 30 or 40 amp breaker i have a 40 amp as my generator puts out 220v 40 amps, after you turnoff the main start your generator, turn on your 30 amp breaker in the panel// good to go
@@arnoldromppai5395 Google or look on eBay for an Interlock Kit. It is a sliding piece of metal that won't let you have the main breaker and generator breaker turned on at the same time. That makes the set up you described idiot-proof. No matter how good we are, we all make mistakes and all have momentary lapses.
Idk why I just watched this but interesting stuff
Same here 😳
Same🤣
Same here 🤣🤣🤣
Same. Just couldn't seem to turn it?
I helped build substations when I was young so I tried to act like I knew what he was talking about
I was trying to look up how electrostatic precipitators worked and found this. I'm not dissapointed and found out some new things. :D
I loved this! So interesting and well made. Thanks for all you do! I know y’all get paid well but also thank you lol
Great video what kind of boots are they wearing...
Respect to all those that work on power lines or with electricity in general!
I just put in a Generac backup generator and a new service panel. The power company guy got up on a 24' ladder and pulled new wires to my new post by himself. That's one gutsy guy because the electrician putting the ATS in said he's never do that.
Great presentation, guys! Well done, and very informative.
I worked at a power company and they never taught us this. Their main concern was how to be corrupt scum bags
PG&E?
Duke Energy?
@@duaned8117 southern company.
Entergy?
FP&L, no doubt.....
How did Rabbit holing from food history to a Hotep Jesus podcast take me here? Any ways, great vid, and ya, prolly the best explanation of power distribution I’ve seen
I dont know why youtube recomended this to me but i'm smarter now because of it. a good informative video
Nice recommendations UA-cam, and question, why aren’t power line wires insulated?
It's because it's easy to tap into them. Also this will give breathing room to the wires. And the main reason is to increase power capabilities. The main problem of insulation is that a fuckup in a line can cause all of the insulation to burn and melt. Imagine this in a larger scale
Also exposure to the elements will create headaches as insulation will break down over the rain etc.
They are insulated, with air. Air is actually a pretty good insulator. The separation is different for different voltages though, as air has an insulating factor based on distance. I don't recall what it actually is at the moment, but something like a kV/cm, or somewhere around there. It does change a bit when an arc is struck, and their becomes ionized.
It costs less , bottom line.
@@robert37042Tn that's the truth!
I wanna see this demo at Texas Huntsville. The real deal.
Going pole to pole seems like it would be very time consuming. Could we not generate a signal along the line at each pole, each with a different value, all added together at certain points. So then when you get a fault, you could just check the values and see which one is missing to pin point the fault location? There's gotta be a more efficient way than going pole to pole... Great video. I'm not a lineman, I'm IT, but I find this very interesting.
What was the grapefruit representing? Interesting mounting choice
I felt the step potential once. We where standing barefoot on a Boulder on the edge of Lake George.. In the distance we saw lightning hit the lake.
We could feel a little current.
Yep. It's basically what kills you, the difference, even if you might survive the intense heat and the shock of the intense sound pressure on your ears and being knocked down, it's usually the difference between either your two legs or (when people still think laying down is better than making yourself as small as possible while having your feet as close to each other as possible, your head and feet) that's the most dangerous.
It's the same what shocks you when you touch the mains: you are at zero volt potential, and the mains isn't.
I’ve always wondered..... perfectly explained I enjoyed watching
Yo the bunny hop out of the car was the realest thing I've heard since, I seen my momma gone forever. Cause thats something we all patiently face.
My tranformer elbow just blew and caught on fire on my pad unit. Took out 3500 homes power. I hope they change the charred cover.
They replaced it. Pud said they had no idea what caused the fire. My light bulbs dont flicker anymore. Haaaa
Wow I learned a lot from this I wasn’t even looking for this
I live near Chattanooga, just south in Georgia. The top power line are 3 wires (3 phase). A storm blow a tree down and it broke all 4 power lines. The 3 phases and ground.
The top power lines were laying on the road. People, with bare hands moved the high voltage power lines. They may have been dead, but something could have back feed.
Some people are DANGEROUS.
Another time a 2 phase line was on the ground very close to a trailer park with lots of little children. I called 911 and they said a downed line was not dangerous. sometimes 911 is not what it should be.
Asking on behalf of a friend. Is it best to pre cook my sossys before hanging them on the powerline ?
How can you scroll past that thumbnail. You can't ! Great job
nice i helped make the plastics for power lines so they don't burn out their is like 5-6 other ground wires in the plastic that can not melt once it is set and made .
Great information - it can save your life.
The instructor's pacing mannerism (back and forth) is described as a Tethered Elephant in the education field. He should conscientiously work on rectifying that distraction.
Dude thanks for saying that. I was starting to feel like my brain was sputtering. Couldn’t really understand why.
Never heard of step potential before but that makes a lot of sense.
Best demo I have ever seen!
It's always impressive when the demonstrator is chewing a cud throughout the demonstration.
@Archer Stetson shut the fk up scammer
Not to mention almost out of breath. 😅

Ask PG&E in California if they favor the tree burning down on a phase 4 air re-closer
Mylar itself is not actually conductive, it’s an insulator. However, balloons aren’t just made of Mylar… they are also coated in a thin layer of aluminum, which is very conductive. The aluminum is why it’s reflective, otherwise it would be clear. Same with a bag of chips: it’s aluminized, and if it blows up against a power line, it’ll do the same thing as a balloon.
Excellent presentation!!
