- Hey Everyone!
After pulling a couple "all night'ers" I wasn't planning on doing much editing this week :(.
This job came up at 3am and I figured I get a couple shots, especially where the wire laid energized on the ground!

When you said that the difference in potential could bleed into you, would that be the case even with the hot gloves? Thanks.
whats 411 on the knox brand?
you should talk about the line men shuffle
Thank you so much for working through the dead of the night to keep our power on and showing respect for the graves too, even if nobody would be the wiser
Random UA-cam watcher here, from Tampa, FL. The work that you're doing by making these videos provides me with a tremendous amount of entertainment value, hours of enjoyment, and a tremendous amount of knowledge. And for that, I want to say THANK YOU!
Awesome! Thanks for taking the time to write that Tom 🤝
Most people have no idea what a dangerous job all linemen perform daily. We are thankful for all of you. Stay safe out there.
Love the real time emergency call videos. As a firefighter it's nice to see what yall do when we call YOU for help! From the states....be safe out there!!
😳 That is totally crazy that it burned the pavement and even started to turn a spot into glass! I hope this vid helps others to understand just how dangerous a down line can be.
Total respect!
Yeah downed lines are nothing to play with, they actually burn back like Candle wicks
Glassy stuff is called fulgarite!
A nice early start . You have to be very careful and take your safety precautions 👍👍👍👍
Looked like a grave situation. 🙂
Been watching your show for about 2 or 3 months. Really like your show. I am a retired electrician . Work in the potash mines for about 34 years as a electrician. A lot different kind of work. I do understand a lot of the things you have to do and put up with getting calls all hours of the night. I like the way you explain everything you are doing.
We thank you guys for your hard work and keeping our houses lit and cool. It’s nice to see how respectful of things like gravestones and such you guys are! Stay safe out there.
We thank them, but we pay the CEO billionaire, instead of them.
I was curious as to how the power lines worked. You are a fountain of information. I enjoy all your videos. Keep up the good work.
I learn without all the explanation. However, after 60+ yrs, there is a massive body of knowledge, needed. I have an OSHA , 10 hr cert. w/the film ind. and have been a trained stagehand for 40 yrs.
I ran a stage band for 35 yrs, keeping musicians alive.
I had a tornado hit my neighbor- hood , 1300 ft above sea level. At 100 ft apart, the poles went east and west, and 3- phase was on my front lawn, then people came..🙆🏻♂️
Anyone else morbidly imagine the sci-fi/horror movie ramifications of the resulting step potential when that long line hit the ground energized right next to a graveyard? Picturing the opening scene of Thriller
your video popped up and I took a look. Quite informing. Enjoyed it. Thanks for all you do to keep the lights on..
Thanks! 👊👊
Awesome work as always , thanks
I love these videos. Thank you for the great work you do, and for sharing it with us.
Always look forward to seeing your videos 🙂👍. Good job.
Oh so that’s tree 🌲 phase!!
Thanks for posting ,always interested
That was super cool!
Always learn something when I watch your stuff Aaron thank you
I found this video to be fun, informative and educational. I really enjoyed watching. Thank you for sharing! ⭐
The work you all do is incredible to watch.
Another great video fella 👍🏻 From Rob, West Wales. UK
Nice work man, and explaining the process.
Thanks for sharing buddy
That had to have been quite the light show. Thank you for everything you do. Stay safe and God bless.
Glad you were able to get some video of that, would certainly have been a light show!
Thank you for sharing this important information. Il look at the grid very differently. Keep up the good work and stay safe
Thanks for the great video as usual was easy to understand the way you explained about the grnding stay safe Erin 1 from John in Massena ny
Great videos. This is a side of the electrical industry I am not familiar with, but fascinates me.
I became a groundman in part to your videos, man. keep up the good work
Awesome! Thanks for sharing and best wishes with your new journey! 🤝👊
thanks man you give me the motivation to retry this job after tchoke one time the lineman school
Good job Aaron.
Knoxville Tennessee here , I bet that was a huge firework show wouldve been something seeing the light show
Watched Ohio Edison fix a wire taken out by a tree. Wire down live and burning grass. Upper wire holding tree popped fuse link. Fuses within eye site from tree. Pulled fused cutouts, cut tree from wire and fire department worked on the ground to finish clearing, grabbed wire, Chinese finger trapped it. Refused the one cutout and closed. 10 mins tops all by himself on the wires with fd blocking. Was cool to see.
Great video as always Aaron. Be safe! 👊👊👊
Thanks Alan! 👊👊
Awesome video man!
Geeking out on high voltage videos. If I were a much younger man and looking for work, I would definitely give this a go.
I enjoy watching the videos and I understand a lot about the electrical issues . In my younger years I knew a guy that was mowing grass for a neighbor and I seen a wire in the grass that broke from a 3 phase power lines and I yelled as loud as I could to stop him pushing the lawn mower he looked at me like I was crazy or something and I pointed 👉 out the wire that was burning up the grass and he was about 6 feet from getting the live hi tension line 😳 and he stop and realize that I just saved his life 🙏🏼🙏🏼✝️🕊😇
Great job from IBEW local 3
Another great job. A long night though, glad the "neighbours" didn't complained about the noise lol
That 1/0 aac is pretty soft!! If that was 4/0 it would have held up longer. Tough stuff. Awesome video!!
Wow that would have been quite the light show for sure! Some pretty serious burn marks in the road there.
Thanks for sharing your allnighter with us Aaron. I guess you didn't get the creeps working around that cemetery at night!!!!
...great movie set-up: downed power line sends electricity through the ground of a graveyard, bringing the dead back to life...linemen show up to repair & are attacked by zombies! Linemen fight back w/ only the tools on their trucks!
🤣🤣🍻
i really like your videos i learn so much keep it up
You are the lineman’s version of a Topgun pilot
Stay safe brother. IBEW LOCAL 47 here.
Good one, Aaron! Another experience for sure! Excited for the giveaway!!! Perhaps us juniors can win some critical gear!?! Definately got some pretty cool gear, and for a competetive price.
You always show safety is the top priority 👍🏻
That is a first for me to see the asphalt burned like that.
The neighbors are quiet now because that bang from the lighting was loud enough to wake the dead.
a few years ago, during a storm, we had a wire break and hang straight down, less than a foot from the roadway. It arced for 20 minutes, and the resulting hole looked like it was drilled into the pavement about a foot deep.
When you see the flash and you hear the boom at the same instant, you know it was way too close!
You Canadians and your _Red_ hot wires :D
Well for a storm fix, you can make double dead-ends anywhere you see fit 🤣
Watching from Boston,MA.. underground guy here, very familiar with 3am calls..
I see you are ooout and aboooot at 3:00am
🤣🤣 Yes sir I am! 👊🍻
We had some storms come threw last month dropped a phase in 1 yard and melted the dirt/sand sorta like lightning does to sand pretty neat little pieces of copper and glass dirt
This is such a great Video. I wish you could get into the safety of it with wires on ground. recently saw 34kv run not only thru direct ground burn marks but also to guard rails with wooden posts and dissipated there as well.. the evidence over a roughly 30 foot area was pretty interesting. Luckily the first responders knew not to get close .
we also have those wooden guardrails with cable. When wires come down it can energize a quarter mile length, so we have to send people quite a ways up the road for safety reasons.
On transmission when we make jumpers we still have to bond the connection before hooking up the last jumper paddle even if it has grounds on both sides.
Прикольные у вас изоляторы ,головка черная а низ белый , у нас не такие все одноцветные 🙂👍👍👍
hey bob would you mind making a video of copper and aluminum hand ties for top tie and neuatral spool ? also if you could do a hot stick one that would be cool too! keep up the good work!
You have balls of steel getting that close to a downed line
...have a friend who's a lineman & his wife swears him being around electricty all day, it's not his b*lls that R hard as steel... ; ^))
Interesting in the intro you showed a car arguing with a utility pole. Earlier this week the main road in town was closed for a day-ish when a vehicle took out a pole.
over at a mobile home park, after a bad snow storm, a branch laden w snow drooped enough
to touch a 7,200 volts primary stringer, the snow evaporated in seconds then the branch and
the tree went in flames.
I’m currently a radio tower climber and strongly thinking about switching careers to a lineman for the better pay and actually learning a skill.
I love electricity. As long as there is a foot of polyethylene between me and the electricity!
Just throwing a stone in the water here, but my guess is that the lightning cooked that phase red hot before it broke free and hit the ground hence the burning. unfortunate that the cable is a wright off. hopefully, there's at least some scrap value on your side of the world. Cheers, Cam from South Africa
In an in-direct way yeah that's what happened. However, if that wire did get red-hot (or at least hot enough to lose strength), it was because of the tree that fell on it causing a short from phase to phase.
Ultimately the lightning just brought down the tree, because while lightning is fantastically powerful, it doesn't last very long.
That means that if a bolt of lightning strikes a piece of metal, the majority of the energy will be spent vaporizing some relatively small portion of that wire, rather than being evenly deposited as heat along the entire length of the wire.
This is why lightning strikes are capable of making trees literally shatter or explode, the sheer amount of power in the bolt causes the water in the tree's sap to boil pretty much instantly, which means that the water (now steam) takes up a lot more room, and the wood is not strong enough to contain that pressure, so it fails by exploding.
However, since there's no water to boil inside a metal wire carrying electricity for the power company, the wire would need to be struck in pretty much exactly the same spot probably hundreds of times before it even started weakening let alone outright failing.
Instead, the upper part of the tree that fell across these power lines up on top of the telephone pole caused those wires to become a significant resistance in the overall electrical circuit, which leads to the wires acting like resistors. And wires acting like resistors is why an electric toaster or a hairdryer can be such an efficient source of heat. So, when the current thru the power wires rises to well above the normal, safe level, they heat up, and that can eventually lead to them melting or if they're insulated, the insulation will probably catch fire first.
In any case, when shorted the power wires on those telephone poles can carry more than enough current to cause them to melt, barring any interference by a circuit breaker, fuse, or other type of over-current protection device.
And even with those devices, as you could see in the video, if the circuit breaker can reset automatically then a downed wire will still cause quite significant damage where all that electrical energy is focused into one arc against the ground. It even made glass, I think that's called a fulgurite. Lightning can make those sometimes, but it takes a particularly energetic bolt of lightning and particularly dry, sandy soil to make it happen so it's quite rare.
@@44R0Ndin The ground was burned because the recloser re-energized the wires while they were laying on the ground.
@@stargazer7644 Yep! If that recloser hadn't been there (and instead either a manual-reset circuit breaker or fuse of the same trip rating was in the same spot), then the ground wouldn't have been burned, and it's likely that the tree itself wouldn't have caught on fire either.
My point was this: Most of the time, when there are both a power line down and a lightning strike causing damage in the same area, the power line will likely be the major contributor to the damage, simply because the overall energy available is not constrained by the short time period a lightning strike exists for.
It's a "tortoise and the hare" kind of thing, in a way.
@@44R0Ndin You really can't say either of those things for certain. Contact with the ground or with a tree isn't guaranteed to draw enough current to even trip a breaker. In that short duration the average lightning strike dissipates an energy of about a billion joules. That's equivalent to a 13kV line drawing 1282 amps for 60 seconds (17 megawatts for 60 seconds). Overcurrent would cut out long before that much power is dissipated via the power lines. The other billion joule possibility is the line sizzling on the ground for an hour drawing 22A @ 13kV.
@@stargazer7644 You're right, it does take a rather "poor/lossy" connection with the ground to produce these kinds of results.
However, it also takes a good enough connection that the I^2 term in "P = I^2 * R" is the dominant factor.
Wet tree branches are apparently a good balance, because I've seen plenty of videos where a part of a downed tree (or the whole thing) is happily humming, buzzing, squealing, and smoking if not actively enflamed, all while sat directly across the phase wires, and the darn circuit breaker or fuse doesn't even trip.
Of course, most of those cases end up transitioning into a full-on flying arc type fault, either because the section of tree that is across the phase wires clears itself from the lines because of being burned away (slowly enough that it draws an arc), or because the debris becomes entirely engulfed in flames and the ionization of that flame is sufficient to lower the air's resistance to the point that an arc can jump from phase to phase.
In either case, you get a gigantic buzz and then silence (aside from any noise the still-burning woody debris might be making due to being on fire).
EDIT: Also, it's important to note that the lightning bolt doesn't focus all the energy it contains in a single point. In fact, most of the energy isn't even deposited where the arc lands.
Instead, it's rather evenly distributed along the arc channel of the lightning bolt itself, and now that I think of it like that, that's probably the major reason that lightning doesn't do much damage to metallic things. All the energy is dissipated heating the air along the arc channel to such temperatures that it expands rapidly, causing a sound which we call thunder.
That's a lot of energy to be dumping into a sound wave, sure, but if you've heard thunder from close up you know it's easily capable of being louder than any gunshot.
If all that energy was released in one place it would be pretty comparable to maybe a mortar shell or other quite damaging munition going off. And since we don't see that happening, we have to assume that the energy must be dissipated in some other fashion.
My primary candidates for the other ways that the energy is distributed are in the thunderclap, and in the low-magnitude electromagnetic pulse that you can pick up on an AM radio tuned to an empty channel on the dial. You'll hear a click or burst of static, that's the radio waves from the lightning bolt being detected by the radio. Some seconds later, you'll hear the thunderclap from that lightning bolt. Then by calculating how far sound can travel in that time period between the static or click from the radio and the thunderclap outside, you can figure out how far away that particular lightning strike was.
This basic approach is pretty much what weather stations use to detect and locate lightning strikes (you might have seen this type of data display on a weather radar app).
The sensors used are pretty much what you'd expect. An AM radio not listening to any particular channel, and a microphone.
The computer running the weather station can be much more accurate than us humans as well. It can use its other sensors to calculate the real speed of sound at the time the static burst is detected by the radio sensor, which is the major factor that degrades accuracy with these measurements (atmospheric pressure, temperature, and humidity should be enough data to get a very accurate local speed of sound).
When a strike is detected via radio burst, the computer starts a timer, and when the thunder is detected by the microphone the computer will stop counting and figure out how far away that was. Some weather stations are even able to figure out what direction the lightning strike came from, by directional radio antenna array, directional microphone array, or a combination of the two. This also allows the station to potentially keep track of multiple strikes at the same time, however even the simpler stations can use sophisticated algorithms to figure out which thunderclap was caused by what lightning strike detected by radio burst.
I'm not sure where it happens, but eventually all this data is collected in one place and then even more sophisticated computer software will crunch the numbers from all the stations and spit out its best estimate of where the lightning strikes happened, as well as when.
In Florida, NASA, SpaceX, and all the other companies launching rockets at Cape Canaveral use this data along with much more to determine if it is safe to launch a rocket or not. The Saturn V might have famously survived a lightning strike, but if you look into that flight they were lucky to escape the lightning strike with as little damage as they did, the Apollo capsule was pretty much forced to be rebooted because of the strike, thankfully the computer actually responsible for the guidance of the Saturn V was largely unaffected (thank IBM for that).
The electronics back then were both much less capable and much more fragile than they are today. Think about it, the entire concept of the integrated circuit was developed for the Apollo capsule guidance computer, and even then they were only putting less than a hundred transistors in each chip, and they were all quite sensitive to static discharge so just think of the mayhem a lightning strike would cause.
I love bringing great people together! #Knoxwork #Bobsdecline
Lightning? Looks more like DR Frankenstein was trying to bring his monster back to life😂...
Well they were in a cemetery 🤣
@@krashd 😂😄👍 that's my exact thoughts 😀
Lightning strike at a cemetery
Dozens dead!
🤔... 🤣
Now that's funny right there, I don't care who you are..... 😂
If they were recently buried, that lightning might wake them back up...😏.
No disrespect intended.
I like the (new?) intro
Thanks! New-,ish... Going to use that intro for most shorter vids now. I'll throw in the classic once n' a while on some longer vids and keep the "being a lineman" intro for those clips
Nice to see you again Aaron. I’ve been very busy with work the past month or so and haven’t had much utube time. Lightning is crazy. When I was younger I never feared it but now that I’m a bit older, I have so much respect for it and a bit of fear of it. Would you recommend I ground my wood burners steel flue pipe? Hope all is well with you and your family!
That tree was just not having it with electricity that day
this looked like fun /s. Murphy's Law, this stuff always happens at night/early morning
It has been a crazy few weeks in the east coast, had one fella cut a tree onto a transmission line recently, no idea if they ever caught him.
asphalt "pops" when it gets hot, when was a kid i remember one really hot summer in MO, you couldn't drive anywhere without working A/C i remember my mom driving me home from school and we saw a notable dirt claud size of asphalt just jump out of the ground/pavement. suppose different chunks and expand at different rates.
When electric goes in the ground in horror movies in a cementary they come alive,so be careful
There must have been one hell of a show when that wire hit the ground.
Definitely would have been some wild! Glad it was in the middle of the night

Don't you people ever want to go to bed?
Just 'cause you feel so good,
Do you have to drive me out of my head ?"
I says, Hey! You! Get off of my cloud

On my cloud, baby
I've seen that happen two separate times not too far from me. One time, caught a tree on fire, and the ground under the chain link fence was turned to glass. The second time, the line was arcing for a long time, right next to a jeep.. caught the jeep on fire. Also, penetrated through the concrete sidewalk, just like through the asphalt. Just crazy. took some pictures of it. They even wanted to replace the gas lines buried under the sidewalk because of it.
Are you going to be doing a video on the power outage from a week and a half ago that had half the city of Moncton without power? That was a big one
Nice burnmarks. lucky it was at night and there where no people around
Just please be safe
I live in Northern California at about 3500 feet in elevation, and everybody's probably aware of the problem with fires California has which, some are attributed to trees falling into the lines our utility PG&E has contractors working and cutting down potential hazards they've taken for trees off of my property.
Most likely that phase had better conductivity to grd.
Years ago went into town (forgot what for) came back awhile later going out wondered why there was a light show in the snow up a few blocks?? Came back the one phase 14.4/25 wire was still dancing not drawing enough current to open the breaker. The linemen had to go to the sub to open the breaker. Wasn't one we worked on!!!!!!!!!!!!
My power company must be doing a pretty good job the past few years, especially with trees being trimmed near poles n what not, sadly havent had an outage in quite a while even with some decent storms passing through.. And i say sadly because i have A LOT of outage lighting that haven't had a chance to be used yet lol.
Regarding that tree, if it were on a home property who would pay for its removal?
Im curious if the deployment of services in the east is using similar or different approach than the way Hydro Québec does it here. Im aware eastern Ontario is tied in with hydro but i have no clue about east side
👊👍
I'm curious if you sell damaged wire to scrapyards to get a small return on what a replacement span would cost.
Do you do any training with the apprentices coming in? You’d be a great trainer for the newer generation ( if you aren’t one already)…Great videos…
I would guess the chunk that jumped out was a result of trapped water boiling.
👍👍
Whatever they’re paying you gigachads, it’s not enough. I worked for a
Major tristate utility for 3years, In infotech, first thing comes to mind when I see what you real engineers do, is “Fck that”/)))
Be safe!!!!
Question: Do you know if there is any difference between the Knox apparel and Bulwark? I work in Building Automation and wear Bulwark FR as I deal with 480/3 panels. It's not required by my current company but experience from a previous employer has me continuing to wear FR gear. Constantly, Bulwark suppliers are always out of my sizes ..
Lets hope nobody waking up at that cemetery😎
Are you using that fab Milwaukee portable sun device?
I wonder if the lightning didn't have a part in it too not just the tree...
If the grass was wet, then it would be hazardous if the power lines was dow on the wet grass. The ground is super energized. Electricity and water are no match. I hope you are safe after this wire to ground contact.
wow thats some burning... (speaking of burning, those headlamps of yours are mega bright, how many lumens?)
How high does the voltage need to be to arc to the ground?
nature can do some interesting things. lightning strikes are crazy at times. Being a electrician since the 1980's I came across some weird things .I remember a storm in western NY a few years back we call October surprise storm. Winter storm with thunder and 3 ft + of snow. weather service reports energy of storm was the same as cat 1 hurricane. The power grid took a big hit. some many people with out power for days at a time. so many trees down . and 3 feet + snow was a FEMA disaster area. many died around hear. some zapped buy down power lines to people running a generator inside home. very sad . I came across a home where the primary fell on to triplex feeding a home. it zapped threw putting 7200 volts to inside a home. burned the panel box inside. arc welding inside. was scary. had to put new service in home. home oner lost all appliances . FEMA claim. no one hurt in that home. but home across the street burned to the ground. pet died . fire fighters had trouble getting to cite. roads blocked down trees. was the worst mess of my life. now I just did a home repair that a tree came down during a storm and broke a crimp on nutural buy pole transformer causing voltage trouble in home. High/low .but 240V was good. Thank you for showing ho dangerous a down line can be.
Looking at all the heavy gauge wires everywhere in your videos I was almost surprised out local electrical company came with a measly 5 x 6 mm2 cable (I think that translates to 8 or 10 AWG?) when we upgraded our board to 3-phase (which is VERY common here, unlike the USA. Or so I've heard). Then again, 3x25A is one of the most common connections we have (or 1x40 for older houses), whereas I commonly see 200 amps or more in the USA, so of course the cables there are going to be much thicker.
Assuming your voltage is higher...
@@ShainAndrews Yeah, voltage in Europe is higher but even taking that into account, domestic electrical supplies seem massively oversized to me.
