- Hey Everyone!
I got this call around noon... found it a bit odd, it was a nice day! A few big gusts of wind, but nothing we haven't seen over the last few weeks. After an initial pass with the truck, I usually have to walk every it of line that's back lot to make absolute sure I didn't miss anything. I lucked out this time, finding the problem at the first spot I jumper out!
Be safe out there everyone! 👊🍻

I should add; That location was passed along to our vegetation dept. and detailed for tree removal 🙌
Willow tree are bad news in a utility easement. You can't keep up with them as they grow fast and seemingly toward overhead utilities.
Hello, in one of your previous videos you talked about and showed a mobile application that helps to connect and test transformer banks. I can't get it, could you please show it to me!!
That tree looked like it was well higher than the wires. I was kind of surprised it was allowed to get that high, but nobody noticed until a branch from it managed to short out the line.
"With minimal Editing" Actually your videos without any big edits are still really nice to see. Keep up the good documentation of all stuff. Always intresting to see how the power looks like on the other side of the Atlantic then Europe I live in.
In those situations where it’s nice if a customer happened to see it so they can direct you in the right direction
A pro at work “oh yeah those willow trees, worth looking at” … problem solved :)
Always worth taking a second look at those willow trees! Lol
@@Bobsdecline Willows make the electrical supply weep (bad joke).
I really enjoy the minimal edit videos. Feels like we are just tagging along. Great work Aaron!
“Too much confidential,information.” He said, while I was reading his screen from his mirrored glasses! 😂 Enhance!
Enhance.....Enhance.....😂
Phase to phase is about 13kV, right? Maybe 2.5 ohms of resistance in the short circuit.
Wood isn't that conductive so I imagine it sat for a while, cooked, eventually created a flame, ionized path, and arc.
Arcing or not, it could have just sat and cooked due to the sap in it (lots of minerals in it to make it conductive), and then when that all flashed off to steam it had heated up the wood itself to the point that it had already started carbon tracking, from there you just have a "normal" if biologically derived carbon composition resistor!
I recognize that area. I am about a dozen houses down the road from that area. Ive really enjoyed watching your videos and learning something new every time.
Very interesting to see the diagnostic process. Even better when the evidence is found and the problem solved (and power restored).
Don't forget the ticket to be entered to have the tree trimmer contractors come through and clear the power space on that span.
Tickets's in a veg. Supervisor was already there! 🙌
Those darn suicidal tree branches give you good job security. If something happens in that area again, you'll know where to look first. Thanks for another interesting video. Please stay safe, and God bless.
I was fixing to mention how well balanced those lines are, but, then you did. Easy done but all ways think SAFETY.
Glad I found your videos. I love watching them. I’m testing for an apprenticeship tomorrow.
I appreciate your videos. It's interesting to learn about the grid and have a greater understanding of what power crews do.
Nice work sir! We common sense oriented folks love, and respect your efforts every time! 🤟
Love your videos!!! I am from Zanesville Ohio. Keep the videos coming!!!
Thanks for Helping keep our Power ON and getting our Power Restored in 25-minutes time. Keep Up the Strong 💪 Efforts. Thanks Aaron! 👍🙏
Air traffic control needs to take a few lessons from you on how to communicate over the radio.
The way you make 100% sure on every communication is awesome.
There have been far too many close calls at airports lately due to poor communication.
Keep up the amazing work! Love your work!!
WTF are you talking about?
Yep. All about safety. 👍🏻🇬🇧
"I don't want to show you the map, too mucn confidential" wears mirrored glasses LOL!!!!! (just busting on ya) :)
even then the angle has to be just right
If it hasn’t been said, you guys are vital to this world. As an HVAC tech I’ve learned just a small example of your day and trouble shoot. Now add in weather and rough storms to make it really fun. Without you guys I would have no job, well actual just about all of us wouldn’t.
Love your videos! I'm an EE, although I don't work on high voltage. One of my favorite memories as a kid as a family friends who took me up in a bucket truck (things were MUCH different back then!). Love learning and seeing how you guys do it out in the field. I did want to be a lineman years ago, and still a bit jealous I didn't pursue that career path. I've helped you guys locate over a dozen power-outage causing faults over the years, and it's fun to spot issues and briefly pretend I'm a lineman lol
Dude, look at that cut! Great video, Aaron. Thank you for sharing your work with us all. Cheers from NH, USA! 👊👊👊
Was there SCADA control available on that substation where dispatch could have closed in the breaker? Also props to the personnel in charge of load balancing.....very little neutral current after the line was heated back up. I am a retired electrical engineer, spent 38 years with electric utilities....your channel is always interesting. Keep up the great content.
Having the head office know more by having diagnostic info feeds from the substations and such is a great thing, but I think that in fault conditions it's better that re-energizing the equipment is only executed by a lineman in the substation's switchgear room, because that lineman will have better info about any kind of abnormal condition that wouldn't necessarily show up on the diagnostic info (such as an animal that got into the substation somehow and needs to be removed while the equipment is not energized.
@@44R0Ndin The lineman in the substation should always do a physical inspection of the substation and the breakers before the feeder is energized, whether via SCADA or the lineman at the substation control house.
Fascinating video. Good work! Thank you for what you do.
That would have been hard to find in the dark. I see those eagle eyes are working well. I find in what I do I sometimes could use a nice pair of binoculars. But watching a potential blue flash would be bad. Somehow, they have still not made it to the truck. Thank you for reminding me again. Sometimes we have equipment we are looking for in a warehouse. Well can be fun at times. Thanks for sharing and stay safe out there. My friend had a large oak tree go down between his house and the neighbors. Somehow it had little damage, and no one got hurt. With very little damage to either home if any. The wind and lots of rain that we had did not help. The tree is now pushing leaves laying down. Nature has a funny sense of humor at times. Maybe it for the Hadi caped squirrels of the neighborhood.
First time watching you today. Interesting job. Good vid.
Always turn off the main breaker to the house when the power goes out. Keep power surges from coming in
Excellent job!
You and you cohorts are awesome!
One thing I have noticed is you have an Egal eye for details like finding that branch in a backlot. That gift of noticing things is probably what kept me out of trouble all these years as well.
Long time viewer, always enjoy your videos and it has made me more curious about the power lines around me. Recently the power company was on my street, hand digging around the base of every pole, then it looks they just put a sheet of something around the pole and reburied it, any idea why?
My power company in CA (PG&E) had a contractor do that same thing in my neighborhood a few years ago. It looked like they were checking for rotted poles. I think they installed a paper treated with something to prevent rot, or maybe prevent termites. Termites are a big problem in CA because the ground does not freeze in winter.
It’s fantastic how in depth you speak because I have been listening to these while I’ve been driving to CDL school these past days. Really enjoyable, you set a great example. Hope to follow in your shoes and teach others some day this trade
Love love the real time videos thanks 😊
Robert, Its relaxing watching you work. You make me feel secure by doing your job correctly.
This guy is a god.
The utility that serves much of our state was found to be the cause of a major wildfire due to negligence in maintaining their lines in forested terrain. It's nice to see the professionalism used in a properly operated utility.
Great job! An easy fix!
Atta boy Aaron!
Another Gold Star!
Hoping you & your family are well?
Thanks Aaron for the great video and keep up the great work that you Do Sir be safe .
Great what you do
It would seem to me that because of that tree’s proximity to the powerline, maybe that tree should be put on a list to be taken down.
Our utility company has been struggling for the last few years to get a handle on the tree problem which has been causing an excessive number of outages with even minor storms. They’ve also had to fight with neighbor’s not wanting their “beautiful” trees trimmed or even cut down. With so many outages, neighbors are beginning to come around to the utility company’s way of thinking😂
This utility company happens to be the largest 3 service supplier of electricity , water, and natural gas in the United States.
Another great video. I love the content, so interesting, keep them coming bud!
I saw a span a few months ago that was so slack the wires weren't even straight. They were almost a spiral like they still had a bit of stress from being spooled up years ago. I've never seen such slacked wires and I won't be surprised if they eventually slap if they haven't gotten them fixed yet. But I do engineering for the fiber company so nothing I can do about them other than report it.
GREAT VIDEO !!!!!!!!!!!!
I sure do enjoy these videos
Hello Aaron from New Jersey! Great video, stay safe and have a good day.
Nice one!
That was going to be my comment, I am amazed at how balanced that is.
Got about a quarter of a huge tree's canopy overshadowing the HV 100 feet from my house here. Leafy small branches already touching the phases, Come the rainy season I know where one power out will be happening.
Good job Aaron.
Nice video sir !! I love your videos.!! We just install a recloser earlier today.. just sharing😊😊 watching your videos help me a lot.. i'v learned a lot from you sir!!🙂😊
Awesome video! Too bad they have to cut that tree. But it is a hazard.
After every video you could remind people,
“As always never get close to downed power ,telephone or any cable lines.All could be highly energized.”
I guessed a branch when all three phases faulted. Short trees are good trees.
Thanks!
Always watching Aaron toasted branches, already had a pre-summer 2 min outage here..were
in the 90's already :)
Nice trouble shooting Aaron. Thanks for the video on a windy day!
Yeah, that was a wacky windy day. Every time I went out back the deck chair cushion was trying to get away. This morning out front, a gust lifted a trash bin, and a bag full of Styrofoam, and scattered it in two distinctly different directions. So maybe not a more/less gustiness, but a to/fro jerky wind. And Willows belong by the river, not anywhere near infrastructure.
We need a video of you putting up a new transformer and putting up a street light
streetlight was just a few videos ago. Been awhile since we saw a transformer on this channel.
I'll make sure I have my cam with me next time I get a transformer change out
Good day for sure‼️👍👊
Could you explain or elaborate why the local fuse did not pop when you were told from the fire department that the customer had called and heard a “explosion“ or loud noise?? I would’ve figured you would’ve had to put in a new fuse for that local service before putting the over all power back on altogether…??
I was guessing branch went all 3 phases showed fault.
Short trees are good trees😉
Are y'all not required to have ground personnel when going up in the bucket in Canada? Much love from Texas love the videos.
Watching you prep your hot stick and talking about safety from an electrical standpoint, where were your cut resistant A6 gloves when handling the arbor saw attachment?
Interesting that a willow branch can carry 5000A!
Willows are VERY wet inside so good conductors.
Lots of things can carry 5000A they just can't do it for very long....
It starts with less current, quickly becomes a ball of fire, and then the ball of fire, having lots of ions in it, carries most of the 5,000 amps.
Excellent video. How do you like the Cooper controls vs the SEL 651R's on G&W Vipers?
It also seems like you guys use more two-way radio activity than we do here down at We Energies in southeast Wisconsin we phased out all those radios out for computer data terminals over LTE man that actually works better than two-way radio that could easily be compromised
Decades of experience give you spidey sense for stuff like that. Fixing signs, I'll have a guy who's five years in, and we'll look at a job and I'll know 95% what the problem is before I even go up in the air. So I'll ask him to figure it out on days where I can afford an extra half hour onsite. It's not to be tough on the guy, it's to help him learn.
nice!
so i have a genuine question, im not criticizing. does your company/LU require you to put down wheel chocks every time you leave the vehicle or only when the vehicle will be unattended for a significant amount of time/off/setup? our company where im at requires them every single time you leave the truck unattended for any amount of time, unless there is someone else in the truck and they will not be leaving it. i enjoy the content as always! stay safe!
Back when, the power company would just reclose the breaker, without hunting down the fault.
If the wind is not at fault , some of those 700 customers need to properly maintenance their A/C . or a new weld shop was sticking it heavy.😊
Do you have crews that go out and clear away trees and tree limbs from the power lines that could cause issues. The power companies where I live do this as preventative work.
@Bobsdecline - Lineman blogger, You may have one already but have you thought about attaching a GoPro to your helmet so you have 2 hands at all time and not struggling to do things with just 1 hand, of course if any info you do not want to show you can blur it in the editing.
Willows are such a dirty tree.
Is that normal to have such well balanced phases ? - 130 amps load - not like that in the UK 😂
They usually aren't balanced quite that well!
@@Bobsdecline Although apparently transmitted as a wye, are most of the actual taps done as delta (phase to phase)?
@@SeekingTheLoveThatGodMeans7648 (disclaimer: I'm not affiliated with any power companies and don't work int the field). Single-phase transformers (like those feeding almost all houses) are connected phase to neutral. Sometimes three phase service is derived from three separate transformers in which case I'm sure the taps are also wye-connected. I don't know how dedicated three-phase transformers are connected. Even if the windings are delta-connected I believe there is a tap on the neutral to maintain system bonding.
Big fan of you and your profession. Curious to what you couldn't reveal at 8:40. Not specifically, but just generally, if you can even do that. Infrastructure security? Large customer? Does your company have specific rules for what you can't show on video or is it just based on common sense
I'd think it would be things that are easily attacked as a prank or worse... maybe?
Super Sunny Day out here, Probably.......4 or 5 degrees......
That's 4 or 5 degrees C, 40 degrees F. He's in New Brunswick, Canada.
Aaron, how can you tell field phase vs road phase?
I have two things to say 1. Your probably the only guy I would want to apprentice under. 2. So how come your always by yourself ? I’m from California and usually I don’t see a one man lineman doing a job. I’m always seeing at least 4. Are you Union or non union
So .. did the recloser close on that line three times? I assume the device can be programmed to not attempt to reclose if the current was over a certain point at fault.
I.e. 130 amps try three times, 5000 amps one try
I'm thinking to emigrate.
It would make my job more eazy.
Do high voltage lines not have an area around them required to be completely clear. Pretty sure around here lines like this have a 5-10m clearing on each side where nothing can be close to them. Pretty sure they can't even be that close to peoples homes here.
this might be a stupid question but can linemen use there hot stick too move a downed powerline if they really had to?
and do linemen use a special kind of harness or can they use any harness that is handy?
Not a stupid question at all.
The short answer is yes. There are of course many things to keep in mind... Step potential being one of them.
If I came across a downed line blocking a road and obtaining a permit to install grounds required a ton of travel time - I could check for voltage at a safe location (likely the next span back) and then use a double hot stick to drag the line of the road. I would then leave a certified lineman on site or stay on site until help arrived.
There is of course many different procedures depending on where you work, but the short answer is yes.
For a harness there are many requirements nowadays for most companies. Full body, arc rated, and trauma straps to name a few.
@@Bobsdecline cool ty for the reply
Need SCADA on that Form 6.
vegies are great, until they're the giant un-edible type that short out power and break buried lines(everything) lol
Which is more challenging, finding the issue in a residential neighborhood or out in the country?
Usually residential due to backlot construction and fences. Unless of course a homeowner calls in accurate information to the fault location.
Rural areas I can usually drive the speed limit and find the problem on the first pass.... Usually.....
What do you make of delta high leg systems? Do you run into a lot of those systems?
I removed the last one in my area about 5 years ago. It's not something we ever install for new construction now. They're definitely a pain!
@@Bobsdecline I am an expert on high leg systems. There are dozens of them in my area.
But with 208Y/120 volt systems you have to use buck-boost transformers for a lot of motor loads especially with air compressors. These services are also known as the wimpy wye
Are lineman responsible for fixing lights out under a bridge? If so can you do a video on that 👍
It depends on where it is. Sometimes a city or other municipality takes care of that.
@@chris76-01 And highway departments are responsible for lights on highways and freeways.
Noice.
Wouldn't that count as a branch circuit?
So, where are you at Alberta?
Canada.
What would 5500A do to a 300A solid door cutout?
For the duration of the fault it wouldn't do a thing. Many of the ascr lines in the air aren't even rated for 300A, but where the faults are very temporary, there's no effect.
On occasion, a weak point in a line (a splice for example) may fail in unison with the protection device.
@@Bobsdecline in theory what amperage would it take to "blow" a 300A solid door?
Hey Aaron, i'm interested in 50Hz (Uk europe et al) or 60Hz (Canada, USA and friends) thoughts from you. Benefits or drawbacks.... Maybe a future vid? Youre welcome here in UK... Cheers, Al :-)
It's frequency.... and it is way more than North America. Dumb question. Voltage is significant... not frequency of all things...
10Hz doesn't make much difference and was only that way by chance. Now with aircraft using 400Hz, that allows smaller motors and inductive components to save weight. But one of the downside is line losses and skin effect. Which in an aircraft, doesn't matter much where saving weight is a priority. But if you ran a city or large grid at 400Hz it wouldn't be practical for the length of conductors. Aside from other drawbacks...
And yeah, most of the world is 50Hz. Don't bother with the previous commenter, no question is dumb if you don't know, it's how you learn by asking.
@@inothome 60 Hz (before name changes in 1968 it was Cycles, as in "60 cycles") is the standard in North, Central, and South America. That avoids interconnection problems and allows all machinery and electronics to be used anywhere on the continent without problems. They all use the same design electrical outlets, unlike other parts of the world.
@@dfirth224 Well CPS to be exact before paying homage to Hertz. S. America is split with 50Hz and 60Hz. Argentina, Chile, Uruguay, Paraguay and Bolivia, which is a large chunk of the continent are 50Hz. There is even a huge HVDC interconnect between Brazil and Argentina to allow power transmission between the two different grids. Maybe be others too, I am only aware of the big one. Then Peru is 60Hz but 220V, not 120V. So, there is no standard "American" power system or receptacle type. But still, more of the world is 220V/ 230V 50Hz than 120V 60Hz.
How long are those hot sticks when fully extended?
I pray the best for y’all. Jesus saves
First😂🎉
🏆
If my math is right 5000 amps at 12700 volts is about 63 megawatts.
The math seems about right. But remember the lines have a voltage drop so the actual voltage at the fault would be much lower in the moment.
@@eDoc2020 I thought that too... but lets say it dropped in half thats still like 30 megawatts!
@@ntsecrets Given that they could estimate the distance based on fault current we can assume it was very close to a dead short. Assuming the 5kA was short circuit current the maximum power transferred into a resistive fault would "only" be 15.6 megawatts. Still an awful lot of power to go through a small branch.
It's always fun watching the master at his craft. Aaron, you, sir, are a true professional, and it shows! 💪🫡
Great video buddy thanks for sharing
