- Hey Everyone!
Hope you're all having a great summer! It's been a crazy busy first week back, not that I expected any different.
While off on vacation, the guys switched out this 345kv line. I was driving home near the end of the day when I got a phone call to head to the 345kv switch yard. It's not often I work or even touch this equipment anymore, so I figured I'd get a few shots of the switching process.
Cheers all!

I apologize guys :( Kept saying 347KV at the start of the video, it's actually 345 KV! In my defense, I had just finished up troubleshooting a 347v service 😅 and tbh, a voltage check would probably show numbers closer to 347kv than 345kv 😇!
It's not often us distribution guys work on this stuff, but man do I ever miss it sometimes... especially tower work!💪💪
Have a great weekend all!🍻👊
Hi Brother can i get the SF6 circuit Breaker current rating and make of the SF6 please...
Is there a technical reason for 345 vs 347 kV considering this difference is not even a percent or is this a legacy thing?
@@neur303 345kV is the standard voltage on the preferred North American list: 69kV, 115kV, 138kV, 230kV, 345kV & 500kV. There are others out there but those are the preferred ones.
347V (not kV) is the line to neutral voltage for low voltage industrial / commercial services in Canada.
We all do that with other technical stuff lol
@Mattew Beasley Thank you a lot for the clarification. I assumed kV instead of V. My mistake.
So I looked it up. Interesting fact to me is that Canada seems to have 3 voltage levels for 3 phase mains. In Europe we almost only have 230/400V. I assume 120/208V is inconvenient to handle industrially, so 347/600V makes a lot of sense.
Thanks again.
the hum has always fascinated me. an invisible sleeping monster "i am here, i am dangerous, come no closer."
That arcing when the switches were not quite closed yet was pretty freaking sweet!
That's only picking up line load! Aka: energizing the lines... Actually load would be devestating to the equipment 😟
@@Bobsdecline I was going to bring that up. What was the arcing for? Is it literally just the lines leading up to the breakers coming up to the same potential, like, hey, welcome to the club?
Yessir that's exactly it
Interesting! I had no idea!
Very cool
@@Bobsdecline Some of the clips in this video appear to be de-energizing loaded lines... ruclips.net/video/VrY_k_pdlCs/видео.html
it's so cool seeing that stuff be remotely operated. I mean I know it's just some pretty basic PLCs but dang is it cool to see it all come together and operate.
I loved how you so calmly said, "This little strap will take the BRUNT of the voltage if something goes wrong" I was working as an industrial electrician at a company in North Canton, Ohio 30 years ago. When I arrived at the switchgear (69KV), I was told it was off and locked out by the electrical engineer and the head electrician at this plant location. I was rather young and new, but as I looked at the bars, they appeared to be fully closed. I argued for some time, to no avail and then grabbed a JLG, to cautiously, from a distance, go up high enough to have a better look. I got about 25' away from the down lines, and the low voltage volt pen in my shirt pocket, went berserk, beeping like it was going to explode. I wrote the company president, after I changed my shorts, and we finally got a training program.🙄
Oh, that's.. yeah that's bad
So it caused you to generate some "trouser chili"?
Where I'm from the rule is: if head electrician or anyone on that matter is allowing you to work, you can demand he first touches the cables / bars he has stated are offline.
@@Sven745 holy that's smart
@@Sven745makes a lot of sense… that said, are there any other methods for ZEV that don’t involve direct touch?
This is very fascinating! As a church organist I have always been fascinated by many controls, knobs and levers, especially with electricity! Thank you to you and all the linemen for all you do!
Love these videos! Awesome to see this stuff working. Several jobs ago in a land far far away I got to participate in some laboratory testing on a 500 kV / 4,000 amp disconnect switch. It was three or four stories tall. Fun stuff! :)

You can never be too careful ! Thank you now I understand The blackout was concentrated in San Diego, and San Diego Gas & Electric, which supplies power to most of the region, said it was still examining how the failure had spread so widely. But the initial cause, it said, appeared to be human error in Arizona that took down a line that provides power to the San Diego area.
i like the vids and i just want to say thanks for what you all do to keep power in our homes....something i would not do and it means so much at what you do thanks so much for you all risking your lives messing with so much power my hat is off to all of you
That’s so cool… very fascinated on all strict procedures and safety you guys follow 👏
I used to like being a line man’s aid getting stuff for the job and did go into big substation’s . And getting to work and hearing the frying egg sound as the morning dew settle on the high voltage power lines.
This was fun to watch. I am working on becoming a manufacturing technician at my job and am teaching myself electronics, starting with hobbyist like arduino. Learning about calculating resistances for components. Cant imagine how strict your discipline must be because one false move and really bad things can happen.
Always interesting , thank you for bringing us along
My new favourite channel 😊, stay safe Man
Awesome! Cheers 👊🤝
My first visit, looks very interesting, will subscribe. Of course some times you do this during a storm -- must be extra fun!
These places scare the absolute shit out of me. I used to have nightmares as a kid of being in a car accident and the car flips in the air into one of these sub stations into all the wires hahah. Still have them every now and then lol
You/ linesmen.. remind me of my old man.. he drove heavy freight locos…, he checked everything twice +.., & made sure he got thing right…
Lol he used to say “everything is ok.. while it’s ok” & “you can be dead right..”
The motor on that switch is bigger than most electrical devices most people would ever deal with! Just for the motor!
hi bob i work on some of those sub with nb power in 83 to 85 built sub at jalbert in st basile and sub at st andré and keswick ridge near fredericton and after that i was doing sub maintenance all over the province untill i went to work for the city of edmundston be safe and keep up the good work
You're fine! We all forget.
Love watching these videos ! Sweet content !
Great to wander where I never will go 😅. Very interesting stuff
Love that HV buzz! very cool video

Why do I get the impression you add in the sound effects before uploading 😄....steel cables exposed to the Mist/fog/Rain amazing what they convince us is real 😉
Why is this operation done? I would love a background to what the dispatch was and why you're carrying out the operation of these switches. If you're allowed to talk about it
Good thing air is an insulator lol 😂
You have to know what you're doing in these substations. If you become the ground path....you are, no pun intended, toast.
Great video I’m slightly sketched out though. So when you manually ungrounded the line I understood it was deenegerized and no power was trying to find ground.
However, had you manually ‘grounded’ the second circuit I understand rubber gloves and boots but wouldn’t that be a high risk because all that power left over finding ground.
Love the vids whatever u can put up ect it must be getting harder with security info ect but like all the input u can post safely is very interesting , me --- wish i had a second life would have been in this industry line work ,
Thanks for this.
After seeing this. I'm wondering how my local utility closed the 115kv line we were working on with all our grounds in the air.
Thanks for sharing buddy there’s a power line like that close to where I grew up I remember walking under it during the summer and it buzzed like a huge swarm of bees lol my hat is off to you guys who work on power lines high voltage scares the crap out of me lol
Recently had a old exploded bomb(it was just some random scrap) scare on one for subs and the bomb disposal guy said he wouldn't work in subs too dangerous shortly before jumping into the hold with said possible bomb and poking it with screwdriver.
This channel has a lot of "POTENTIAL". (Drops🎤)
Lol
That connection to thebfround mat is sketchy AF. Should be a nice chunk of 2/0 copper running from the handle through a connector on the steel structure making a continuous loop under the mat with 3 connection points, then back up through the connector on the steel and crimped to itself. This ensures there is multiple redundancy in case of a failure. I've seen way larger arcs on ground switched than on line disconnects. Also, those are SF6 breakers, not air.
That's something I've never seen before, of course. So, if I understand it. The first thing you manually did was cut power on those 3 in-line switches? Then you set up the other 3013-01D so it could be energized remotely?
Video should be titled "A tour up my nose" Or "The caverns of my konk".
That mullet!
I'm assuming by the bridge-type tower designs in the background that this is a Canadian installation (switchyard) served with dual 345-kV circuits. Am I correct?
Yessir 🔥
I can hear that 60Hz humm
1:36. Gave me a buzz.
Really cool video!
Why do you keep your car running all the time?
I wonder how much power we're sending over to you guys across the Maritime Link?
It’s strange for me to see Overhead guys doing any kind of switching inside a substation. In Chicago that never happens, overhead only switch on 69kv,34kv,12kv and some 4kv switches only out in the field. In Chicago we are called Area Operators where we do all the transmission and distribution inside & outside the substation. Our union rules don’t allow overhead to switch on certain switches. In Chicago you would never be allowed to switch within the substation, union rules.
I would imagine the more densely populated cities would have more specialized disciplines of work due to the amount of equipment. He looks fairly rural and probably wears many hats. Were as Chicago metro area probably has 200 or 300 substations. So you probably have overhead line crews, underground line crews, substation distribution, substation transmission,.... that specialize in specific areas of the system
@@TnTBLACK95 that is correct we were specially trained by the company to only perform that one job. I was trained for transmission & distribution switching were our overhead was only trained for distribution, there was no cross training.
@@stevetaylor205 I have worked in our network underground(vaults and manholes), substation maintenance, Power Quality(glorified troubleshooter) and our System Lab. I've been fortunate enough to work from the power plant to a customers receptacle and anywhere in between. Dont know everything but feel like I have decent understanding of our system. We have about 1 million customers, about 50/50 suburban and rural. Depending where you are geographically and your skill sets will dictate what is performed, at least to some degree.
wow nice to meet you dear bobsdecline im like your content
Why are those switches not automated, as in remote controlled ?
$$$
lol you use ABB french brand, why not an american brand?
You mention "AIR Breaker." Is such a thing used on a 345 kV line?
I'd have to clarify, but I'm pretty sure they run at 2000 psi. Only our High voltage electrical mechanics are allowed to touch any of the components of the compressor and air lines
@@Bobsdecline -- OK. I'm guessing that high pressure, dry air is a good insulator. Thanks. I learned something.
I think the operating mechanism is operated by air, but the arc is probably extinguished by SF-6 gas. I am a retired sub maint. nerd. Thanks Aaron for your videos, I savor them like good food cause I miss work.👍👍👍 Stay SAFE!
@@guzzilm3 -- I tried to find out more about these. Compressed air is useful for quickly operating a CB and it's also useful for blowing out the arc. I didn't find Google to be helpful, however.
Most of our sf6 gas interrupters have indicators, I didn't see any on these switches but I'll definitely clarify with some of the guys that work on this stuff
The noise alone makes the hair on my neck rise. Thank you to you and all of the linemen that keep everything powered on.
And that was just the static charge on the de-energized line!
hair of the neck? ....first time i hear that
I love that noise, it sounds so powerful and regular.
I never got used to that noise in the switchyards or on the transformers, or on just about any of our equipment over 480v. I was an operator at the Wolf Creek Generating Station in Ks. I got to the plant one evening when basically we weren't doing anything but baby setting. We started in heavily bringing systems online about a year later. Anyway, a 13.8 kv line suffered a phase to phase short just about 15 minutes before I got there and it was the 345 kv plant feed breaker that finally tripped to isolate the fault. But it ate up 2 13.8 kv breakers in the process. It was a mess. Major fried equipment. Delayed us getting online for 6 months. We were only running 4 man shifts when this happened. Everyone was rotating in & out of training I had to spend about an hour in the switchyard that night and the coronas just always made me nervous. But I do miss those days.
This guy's a huge asset to NBPower and a credit to his profession. It's great to see and try to get some understanding of the intricacies of the power grid. It's a complicated, tedious, and dangerous job, but it's great to see the dedication and professionalism of these people.
Appreciate the comments very much!

It's workers like you that keep us powered up and watching RUclips! Stay safe and keep up the awesome work. In our world of uncertainty, at least we can count on individuals like you to ensure our daily lives. Love the videos.
"Everything sounds like it's energized" That statement alone is frankly terrifying.
Thanks for your service. I wouldn't get anywhere near that area. 345,000 volts is a scary concept!
I worked 115kv substation air break switches for 45 years. Each open was memory! You tend get used to the display and sound but are always on alert for something unusual.
Love the fact her say bonded and not just grounded like I hear from so many which is a more correct term in the industry. Really appreciate the videos, just residential electrician but love learning how all the electrical systems work also. Have a friend that was a line man so have even more appreciation what he did too!
Amen. Bonding and grounding are not the same thing!
Here where I live, our local PUD is installing a second high voltage transmission line to our island for redundancy. We get a lot of windstorms here in the PNW and we will often have whole island power outages so it's nice to see them doing this. They have never been involved with construction though as they have always contracted it out so it's interesting to see how excited the crews are about doing this. They built a brand new substation in town and will build a new substation here on the island at the end of the project. Looking forward to watching as the work progresses. Seems to be pretty interesting.
If you have windstorms, why aren't they installing an underwater line?
Always been fascinated by electrical infrastructure, enjoy the first person information, now, when I look at those places, I sorta understand what is happening there.
Good to see there are so many safety mechanisms in place. Thanks for sharing Aaron! 👊👊
In designing anything like a power system, you need to make sure that there are redundant safety mechanisms and that there is no potential "single point of failure".
Question: it appears that you are removing another lineman's tag. Isn't that counter to what tags are for? I'd be grateful if you could explain that. Thanks and keep up the great videos!
Can't speak Aaron but we tag most equipment to the Distribution Control Center. The DDC maintains the tag and permits. Only the DDC can release the tag for operation.
Somewhat similar here...
Our energy control has a switches tagged on "the system".
The permit holder surrenders their permit to our dispatcher, the dispatcher then has filed personel do the switching and remove field tags.
The tags have the permit holder as well as the installer/removers name recorded. They can't be touched until both the permit holder and dispatcher give the ok.
Often times the permit holder (especially on the transmission system) is hours away from their protection points.
On our system if it’s a do not operate tag and I have control for the day while we are working on that line. (Usually fused branch lines) if it’s a tagged switching point in a main line feeder it is issued to the DSO ( district service operator) and they have authority over that tag. Meaning that if I am working on that section of line I need to get permission in order to remove that tag at the completion of work. Say if I do not complete the work and a different crew is coming to relieve us then the dso maintains control over that tag and issues permission to work to that new crew under their tag. But when the new crew takes over they need to verify all tagged open points and possible back feeds, then take out a new clearance in order to test dead and apply their own system grounds. Again if I am working on a branch fused feeder that tag is placed by me with my contact information and that tagged cannot be removed and line energized without my permission. Every system is different, hope this helps
@@Bobsdecline here in UK on transmission subs POIs(not remote ends though) and fixed earths would be locked with a unique key that goes into Keysafe that an Senior authorised person(SAP) would put into a key safe.
Then that safety key is issued with the safety document to Premit holder. Permit holder then keep that key in there safe custody until they remove the working party and surrender that document.
Interested to hear to hear if you do similar
That would be the case in "Lockout Tag" (LOTO) but electric utilities Per OSHA can use Switching Procedures direct by system control in place of LOTO.
The other end of a transmission could be 100+ miles away and control by another utility, so tagging would need to be done by System Control.
Hey man! Look at the traction you are getting on your channel. I love this channel and want to get you to a million subs. Love the content.
I spent 13 years as a Nuclear Plant Equipment Operator (N.P.E.O.) at a western nuke plant. One of our watch stations included the switchyard tour a couple of times each watch. One evening I was touring the switchyard and passing by one of those air operated breakers when the control room cycled the breaker. Why I have no idea but this occurred at maybe 0300 when I was trying very hard to keep my eyes open. So he hit the switch in the control room and literally scared the pants off of me. Unless you have been standing beside one of those breakers when it cycles unexpectedly you have absolutely no idea how loud that can be. They really cycle nearly instantaneously so as to limit arcing across the contactor points during the cycle. After having my heart stop for a few seconds I went into the metering shack and called the control operator up. To say that I was angry that he hadn't called me to see where I was before he cycled that breaker doesn't even come close to tell you how tense I was on that phone call. From that point on the control operators had a placard by the switchyard controls telling them to call the "Outside watch" to advise them to clear the area before cycling a switchyard breaker.
I am really enjoying your videos. They really bring back memories of what I did as an operator. Operating a nuke plant is by far the most fascinating thing I have ever done. I am 80 years old now and retired. Good stuff Sir. Thank you!!
I build the meters in those types of systems. always interesting seeing what goes on inside the substation.
The nation' s electrical energy lifelines depend upon sober, dedicated professional workers like you. System designers and engineers are of course essential, but without trustworthy professional skilled linemen, all would be for naught!
I love these substation videos, keep ‘em coming champ
Shocked myself again just changing a cracked light switch cover... I'm glad people like you are out there doing this work, I'll stick to baking cookies and pies, I'm good at that :)
Just do what he does, turn power off to the device before you mess with it.
@@richardred15 there's quite a few ways to get a fetal belt in a substation even on kit thats off
@@stephenrowley4171 Given that they got a shock changing a switch cover, I sure hope they don't go messing around in a substation.
I've gotten a shock off a 240V circuit that was supposed to be deenergised after flipping a main breaker and pulling the main fuse. However there is a semi-detached granny flat on that property that the landlord had gotten a separate meter installed in, to rent it separately. It was still energised, and some of its cabling apparently runs through the same steel conduit as this circuit. Two parallel wires and a ferromagnetic core… that's a transformer. Creating a full 240V potential to earth even though there was no physical connection. I was treating everything like it was still live, wearing rubber gloves, but even then I made a mistake and my bare arm brushed up against the wire… fortunately limited current due to the coupling… if I'd used a multimeter first I would have known! There's a reason all those procedures exist.
Just do what he does, verify that the line is deenergized.
Really appreceiate the HV videos as well as your attention to procedure. Stay safe
Thanks Matt! Cheers!
Hey Bob, I'm not a lineman and I have much respect for what you guys do along with the System Operators and Engineers that design and operate these dangerous work environments so that we can enjoy the world of convenience that we live in. That said, I am a network engineer that works with SCADA telemetry equipment and I was trained during my sub-station training to walk through a sub-station in a shuffle step manner so as to never potentially lose contact or allow myself to become energized. Your footsteps seemed to be contrary to what I was told. Is there a safety risk that I got wrong?
Does a person in your position have to pass a hearing and or vision test? If so, how often is a person's hearing and vision tested? Thank you for your professionalism and hard work.
Not sure what the requirements are for the power company, but in the USA he'd need a physical every two years to have the proper license for driving that truck. (commercial driver's license) That would include both hearing and vision checks.
Very nice! Good to see all the safety and check-off lists! Thanks for showing this operation! Stay safe!
Electrician here. Very cool to see what goes on in the daily life of a lineman. Appreciate the attention to detail and dedication to your trade!
Interesting watching you perform switching operations. Do you have mechanical and electrical interlocking to prevent equipment being operated in the wrong sequence. If say we open a disconnector and want to put an earth switch up we have to remove keys from the disconnector that then go into the earth switch to allow you to open it. Typically you might have main and reserve busbar disconnector keys and line disconnector keys all go into your earth switch to allow it to be applied. Only a couple of weeks ago we removed a 400kv earthswitch on a line and the induced voltage was pretty epic, pulled a huge arc.
Seems good ones pulled on 275kv on some line end.
Generally in North America, nope. The only automation will be in the dispatcher's computer system. `
Same, we have interlocking and we never field switch alone unless it's an outage or emergency.
This was freaking cool. I had no idea they did "remote" switching like that. Sounds more safer. Thanks for sharing!
One hears about static during energizing but it was wild to here how much static there was before the airbreaker closed and took up the load. As always thank you sir
So, I you gonna tell how to find lines map in the area where I live? Near Houston? Or is it huge secret? Why I can see Entegry maps on their website and why I cannot find anything from Centerpoint? Thank you.
Hi Aaron and thanks for your video. Nothing like getting your daily dose of EMF! That's a very cool sequence closing that switch. Would've loved to been there when it was opened. As you said that it was something you don't do everyday. But we all know that opening and closing switches is good for maintaining good equipment operations. It's also good when utilities can drop a distribution feeder without interrupting normal operations to customers. Thanks, jk
-Outstanding shipmate. Press on. USS Kitty Hawk CV-63. Jan 1980 to July 1983.
Ground switches are often used to lower the potential when an adjacent line is still energized. The adjacent line might induce voltage on to the open line.
And in case somebody for whatever reason switches the line back in, the short circuit will trip the circuit breakers and probably safe the personnel.
Edit: Typing
@@legominimovieproductions still should test and ground both sides of work area and never rely on ground switches!
Induction is ceryainly a big concern, but so is static charge. Wind blowing over a floating line segment can build leathel level of charge.
Few people realise or fully understand the importance of keeping one phase bonded to ground at so many points.
I always explain it by saying that if all the phases were floating and a fault took a phase to ground, nothing would happen. Then if another phase grounded 1,000 miles away, you would see the world's largest firework display.
Fantastic !347V the shaker !Came across that once or twice .345kv not at all .150kv ,27600 13.8 old 4160 .I'm just a sparky don't play with big toys but on occasion I get to see some crazy work !Brave men and women!
When you day air breaker are they actually air blast or SF6?
Those are SF6.
I'm always curious about how different professionals do their jobs. Thanks.
Going to Lineman school right now and these videos help me feel more comfrotable moving forward. Even tho I don't know what much of this means, it's nice to see your work flow and what you deal with.
having worked on high voltage, you must work on such equipment without being tired, and generate a check off list so mistakes are avoided.in this work you have got to work with safety in mind ,due to the fact you will not get a second chance. with that potential ( 345 kv) you will be vaporized ( strike zone is 10 feet). never get to a point where you get lazy, or operate with out safety in mind ,otherwise you will get killed. with that potential you do not have to find it, it will find you. I am not saying this to scare you ,I just want to see you go home at the end of your shift, and not become another statistic. never assume that a line is de- energized, there is static charges on the line, this can include induced voltages from another line set that is active ,that is why you always ground the line set before working on it. I myself hated working on live lines, there is too much that can go wrong!!!!!. I wish you all the best ,and stick with it, do not give up on it.
Which school you going?

@@gregoryclemen1870 Exactly. This video shows why that is. With the stakes this high, even the remotely operated switches require hands-on work on a regular basis. And I think we know electricity demand isn’t going anywhere any time soon.
Hi Bob, I live in Quebec, in the "bas Saint-Laurent" and there's a big substation close to where I live. There is a big antenna on the substation site and it looks exactly like the one on the video. At 1:56 With big dishes. I've always wondered what it is or was used for. Is it related to the substation? Thanks
I'm a power system operator in the States. Our subs have these with microwave antennas to serve as a communication path for system protection relay schemes. There are sensors monitoring frequency/amps/volts for every line and their associated busses at each end of the line. The relays use these sensors to look for a fault, and if one is detected it can use the microwave antennas to signal the breakers at the other sub down the line to trip, or trip and reclose. Dense fog can impact microwave communications, so at least in my system the microwave comms are used as a secondary communication path for the relays, with a fiber network strung on the same line towers is used as the primary method of communication.
Probably more information than needed!
@@pat90 wow thanks a lot, I'm in IT and I'm very interested by big electrical infrastructures. I understood everything you said. Very interesting and smart!
Now I know what these are used for!
Thanks Patrick!
7:19 I would imagine they are SF6 breakers operated by air.
That is so freak'n awesome!
I recently was hired as a substation drafter, and seeing the real thing I've been making doodles of is neat.
Random question, How tilted can poles be before its an issue? I regularly see poles that are visually 15-20 degrees or more off vertical but they never seem to fall over.
I set these switches up quite often. In the open position, the poles should be at least 90 deg, or 2-4 degrees over. Many times we are working on something on the bus and find some old switches at angles less than 90 deg and if it's possible to adjust, we will. Sometimes it's not possible to obtain, as going further open will affect how well closed the switch is and the positive toggle (locking) that is obtained upon closing. This may be due to someone cutting one of the coupling poles/rods too short long ago when the switch was installed. Last year I was working on a breaker replacement and the bus side switch was at maybe 80 deg. It was not possible to safely adjust the switch, which was 40+ years old, so prior to making our work area safe, we fabricated a device that held the switch open via a plate and some clamps. We notified maintenance to address the switch the next time the bus and the breaker we replaced would be out of service.
@@Boldaslove71 i think he is talking about utility poles not actual switches.

Quick question, what's your guess on how many amps are flowing in the Tie-lin coming in to the switching yard?
Also, is the power factor on the tie-line near unity? Thanks In advance.

They really should have a second person with him during this, just in case something goes wrong.
Depends on the company. I've worked at both kinds, where single individuals were allowed to enter and operate equipment, and others where the 2-man rule was policy.
Really interesting to see this happen, shame the camera ran out of space for more! Thank you for bringing this to the internet.
Use the GIS for replacement of CB and disconnecting switch, no arcing and no electric spark sound
Do you call your dispatcher to confirm right before you manually operate a switch? Or only call in after you've done it?
Wouldn't the world be so wonderful if there were never any switches for anything. Energy, all the time, 100%. It's kind of similar to how real men don't use brakes. -Deep thoughts by CP, enjoy! Nice video, once again but not so nice because there are switches. :) Maybe solder them all together next time? That would rock.
Excellent lesson and most importantly; thank you.
Is it normal to work alone in these tasks? I'm not used to seeing that just for double checking purpose?
Electrical engineers and electrical technicians really do like working together.
ETs helping EEs in keeping their stuff in operation
I fell asleep 😴 watching this boring nonsense
In Australia the equivalent voltage rating is 330 kV.
The lower half of our district just north of Sydney (Newcastle & the lower Hunter region) is supplied with power by 2 × 330 kV feeders which also supply power to our local aluminium smelter,14 years ago, someone accidentally tripped a circuit breaker for those feeders ar the power station (Eraring) which totally blacked out the southern part of our district.
When they were beginning to construct a new 132/11 kV substation in my town in 2013 I was surprised that I wasn't hired as an electrician in the construction phase of the project when I only live a couple of kilometres away from the substation which was commissioned in 2014.
Another substation which is 33 kilometres away from our town is said to be upgraded from a 132/33 kV substation to also include a 330 kV transmission line which is supposed to be connected to the aluminium smelters high voltage switchyard by 2027 but I don't see that happening by then,I don't know where the corridor for that transmission line is going to be yet.
A few kilometres of the 132 kV transmission line consists of a twin 330 kV metal tower structure & some of the 330 kV structure utilises concrete poles but it then connects to a 132 kV structure.
One of the feeders on the 330 kV structure is meant to eventually be connected to a continuation of the yet to be erected 330kV transmission line which is to connect to that mentioned substation (Stroud) by 2027 to meet the demands of the population growth on the mid north coast of New South Wales.
The other feeder will be kept as a 132kV feeder which will supply my town & the other substation (Stroud) with electricity by a currently erected twin 132 kV concrete structure,one of the feeders has been repurposed as a 33kV feeder which has kind of superseded an 88 year old 33 kV feeder which is not operating now.
They're also meant to be building a battery depot in our town which will store the electricity generated by rooftop solar power into 6 Hectares of batteries, that can be offloaded during the night when it's needed but no construction has even started this year !
im very suprised you're allowed to shoot inside substations. Im also suprised about the lack of safety equipment...
Interesting informative video as usual, and my what a satisfying sound of the electrical connection being made at the end there. It brings home the notion of the level of voltage with which you and your colleagues work, and the importance of safeguards such as the ones you illustrated leading up to the big connection.
excellent video, really appreciate learning about what we all take for granted every day
