I would doubt SF6 would be used, as you would need pressure gauges to ensure its filled. As far as I know, SF6 is only used in switchgear primarily to save space. SF6 is a great insulator whitch is not only use when trying to limit the arc but also used to minimize dimensions and the shrink the switch gear. I'm actually surprised it's still being used and developed in the USA, as Europe is now getting away from it because of its environmental effects. I personally used it in France and Germany and it was a b**** to get on site as it could not be flown .
Im new to the URD side of things, but my guys are lineman also. Everyday is different and it blows me away at what these guys do up there, your videos give me a better understanding of the job and the lifestyle. Thank you!!
One safety habit I've used over the years when closing or opening switches is to #1 look over the switch for problems and then line up your shot to close it. #2 ..Put your chin on your chest (this allows the brim of your hard hat to cover and protect your face and neck protecting vital arteries in your neck). #3.. Take a big breath and hold it ( what this does is keep you from sucking an arc into your lungs God forbid something should go wrong because if an arc or explosion does occur it will startle you and cause you to breath in suddenly). #4 Send it home firmly using enough power to close it and not break it. I like your videos "bump, bump"
These are the kind of videos I love! The ones that actually show how mechanisms operate, and how particular operations of jobs are actually performed. Nice video!
Not sure the comments made before on SF6, but SF6 breaker internals are pretty cool. There are interrupters inside and the way it works is when the movable contact pulls from the stationary contact it creates a void inside the interrupter, sometimes called a puffer, and this creates a low pressure area that is then filled by the SF6 gas through ports and helps to blow, or "puff" out the arc. The entire inside is of course filled with SF6, but the interrupter creates this lower pressure area inside the interrupter portion. Oil filled breakers do the same thing, but instead of using a gas to cool and quench the arc, it of course uses oil. But the same principle with an interrupter and a void when the movable contact pulls from the stationary contact in the interrupter. In fact, the SF6 breaker interrupters were designed following the interrupters found in oil breakers, since the oil breakers of course pre-date the gas filled breakers. In a vacuum breaker you don't have any of this going on. In a vacuum breaker it's just the absence of air that prevents the arc from ionizing in the first place. But vacuum breakers are only viable up to a certain voltage class, which is about 35kV I believe. Also in a vacuum breaker, as I am sure you know, the distance between the contacts when open in a 25kV vacuum breaker bottle is less than 1/2 inch! That is why you never trust a breaker for an open and always use a physical visible open. And I am sure you know the tripping time on most breakers is in the order of three cycles or less! At 16.6 milliseconds per cycle at 60Hz, that's less than 50 miliseconds to open and quench an arc. Amazing some of the higher voltage class breakers can move that quick and some of the 500kV class breakers are even faster. I love working in substations, so much interesting equipment and technologies that most people don't realize goes on in there. I've been enjoying the videos, keep up the good content and work safe.
Excellent description! I worked at a Nuke Power Plant for 11 years. The switch yard used 4 cyclone 500KV line breakers that used high pressure SF6 gas jets to quench the arc as the flying contact rotated 230 degrees inside the enclosed breaker (which looked a lot like a donut without a hole). The breakers each had a compressor to recover the SF6 gas after each cycle. The flying lead rotated around the center axis on an insulated arm driven by an enormous high tension spring. I don't remember the opening time, but it was very fast. These were unique breakers made for the nuke plant that were nuke safety rated. They were $$$$$$ each and were only rated for 4 loaded opening cycles, one of which was used during acceptance testing. I asked if they could be rebuilt and no, after 4 cycles the insides were burned too badly to be reused. And yes, they had to have a full set of spare breakers in the warehouse on-site. We also had one of the primary 500KV transformers blow up. It was in a 3 sided concrete blast shield and luckily no one got hurt. The transformer was caring 1150MW at the time. Understand that the primary transformer is huge and weighs around 1,000,000 pounds. What happened is not frequent, but not rare. What happens is the cooling oil inside the transformer casing gets contaminated with too much moisture causing an arc, and once it arc's, kaboom! (It was heard about 2 miles away.) Normally, the oil circulation system removes water and contaminants from the cooling oil. The identified cause was the oil cooling system from the time of installation over cooled the oil, allowing moisture to be absorbed. Where does the water come from? Amazingly, through the transformer's steel tank walls! Over 4 years, the steel was porous enough to allow enough moisture to be introduced into the oil (it doesn't take much). The company's own on-site engineers didn't bother to pay attention to the manufacture's recommendations and figured more oil flow through the cooling system was more better. The oil was supposed to run hot to drive off moisture...go figure... Same thing can happen to pole pigs if they get moisture inside due to leaky tanks or damaged connectors.
Where were these videos twenty years ago? This information would be great for Apprentice Lineman. You can definitely tell you know your stuff and you have such a natural ability to explain things in an easy way for everyone to understand. Thanks for Sharing, Love your channel as always.
Fairly new apprentice. It's been pretty difficult to get a grasp on things but I've made a lot of happy journeyman because of your helpful videos, I appreciate all the time and info you put into the video on and off the camera. From a young apprentice thanks brother. Stay safe👍🇺🇲
Hey Missouri from USA here, really enjoy the videos. I'm not an electrician or anything I just enjoy your videos. Explaining what a door was was very helpful, I I've heard you speak of them but I never knew what they were thank you keep up the good work
Hello, greetings from Spain. I am a professor of network development and transformation centers. Congratulations for your excellent work and for providing what in a classroom is impossible to teach (for space and money). Best regards.
Thanks for the video. As a previous distribution engineer, it's nice to see how these things come into play in the field. It's hard to get a grasp of how everything comes together behind the computer screen.
Loving these videos from Salt Lake City, Utah! I never ever thought about being a lineman; actually hate working with electricity but find it fascinating. You make this trade look, for lack of a better word, interesting. I know you post these videos mostly for other linemen, but thank you for the explanations in terms that everyone, lineman or not, can understand. Stay safe!
Hey Brent! Manufacturer recommends an inspection every 1500-2000 operations. There are a few wearable parts inside that will need to be changed ... As long as it's well looked after, there is no expiry date
@@Bobsdecline is that 1500-2000 actuations because of the liner that reacts with the arc to quench it? Or is it 1500-2000 actuations because of the spring and other mechanisms? Just wondering if practice runs, like you did in the video, will count against it. Like if you check it ever time before using it (by doing a test actuation), can you go to 3000-4000 actuations?
Worked for a few years with Pacific Gas &Electric in San Francisco. I worked in the underground...manholes in downtown. Lots of lead cable back then...everything you find on a pole, but in a hole...lol...stay safe!
Brissy Australia here. Very cool to see this gear in action. Many years ago I used to work for a company (T-mac) that made a lot of the gear you show including Hot sticks. Though I was in the section that made test lamps and the likes.
Hi from North Carolina USA, interesting work for sure, when I was a Firefighter I got to see the power company quite a bit. I admire the safety and personal accountability that's taken by them, 2nd to none, doing a ultra hazardous job. From Trees on lines to Structure Fires it was common to see Power Co, got to know the fellas in the area pretty good. Your vids were in my Recommended I watched and subbed, stay safe thanks for the videos
Scranton, Pennsylvania really like your videos. Sorry to say here in Pennsylvania the major power company, Pennsylvania power and light (pp&l) would most certainly fire someone for doing what you are doing. It's nice to see you have the support of your employer, must be good people! Thanks again!

Load busters in my time were only good for a certain amount of operations. I always had that in mind when I opened a fuse under load. Never had one to fail.
Watching from the UK; really enjoying your videos. Total respect to you and your colleagues worldwide for doing this skilled and risky job to keep our power on!
Very interesting videos. I am no electrician, 35 years as an auto mechanic but growing up my dad had 36 years with Public Service of N.H. Interesting to see what he went through on those long stormy nights he was gone.
Greetings from Indy. We use load busters often. Not for just dropping load. But also to handle the amperage difference when separating mainline circuits. Great tool! Thanks for the vids on trouble work. Working on a one man truck can be challenging at times. Keep up the good work👊
I hear a slight Newfie Accent. I was born in Newfoundland--in Alberta atm. Love your channel. I've been giving serious thought to going for journeyman electrician.
I am watching from Dundalk Md US, I am new to watching videos about being a lineman, I have always wanted to know what you guys do, thanks for doing these videos, I find them so far being very educating , stay safe
SF6 filled switches are a pain to maintain. If they go too long without inspection and drop into the red you can't operate it and you have to deenergize the whole switch to fill it up back up. My utility is going away from the SF6 switches to oil filled.
👊 Watching from BC. Not a lineman but I love the technical information on how our infrastructure works and what it takes to keep it safe and reliable. Great videos, keep up the great work on the job and the videos man!
Do you guys use a tension puller switching tool Chance C400-1907B? All I can find is a couple of still pics. It would be interesting to see it installed with your narrative on the operation. Curious to see if the switching tool can be used with a load buster.
Okay so the white powder in HRC fuses is there to help stop the arc because it's a fine ceramic powder. It will absorb the metal vapours and cool them instead of them conducting and keeping the arc up. It's ceramic because it's insane hard to melt and it will keep up the massive surface area used for absorbing. Even in small HRC fuses for multimeters and such they use more or less the same quartz or ceramic dusts. As for SF6, it just doesn't conduct much and it's difficult to ionize but most of all the contacts won't corrode that much because it flushes out the oxigen from the system that would cause rusting and scales on the hot parts under the arcs. Not contained in the loadbuster though
Awe Aaron you got a haircut man hahah!!! Just had a cut out break on me the other day luckily it was a clear break and nothing flashed so dodged it thank goodness! Great video as always and always stay safe! From your friend from Kansas man!!
Greetings from Nisula, Michigan 👊 Thanks to your videos I can look on power poles and understand what's there, like the transformer I was wondering why was there when there's no houses for a few miles around it is actually a voltage regulator.
Watching from sunny Syracuse, NY. Been curious about power distribution since a little arc-flash incident at work (Michigan, 1990's), where a couple cubic inches of copper (section of a 480v buss-bar) turned into plasma - a real attention getter.
new subscriber from the UK... awesome channel. Learning how you guys do stuff over there. I'm an LV guy so we don't do much over 415v (see a bit of 480 sometimes on split phase supplies but they're rare). but it's interesting to see 'how the other half' live. Interesting thing about work here is that our fault currents on the LV network tend to be larger due to larger and fewer transformers (a typical unit here is 750kVA continuous rated 3ph 11,000 to 415/240v, close to the substation the LV side can have fault currents into the tens of kA. Kudos to you ... stay safe
🤜 Kia Ora, subscribed and watching from Auckland, NZ. Great video, we use load busters alot on our network where we can and isolate the circuit if we can't use a load buster to open cut outs. Interesting how you say people asking why you look away, here in NZ, we are trained to look away when operating switches etc for exactly the reasons you explain. Stay safe out there everyone 😊
On a few transformers around my neighborhood I've noticed a little incandescent light bulb on them. What are those for? Are they just an indicator to show that it is energized or is it connected to a thermostat that turns it on if the transformer is getting too hot?
When you say the inside of door is coated with material to snub out arc, does that mean a blown cutout should be swapped for new if that lining is degraded from previous break?
So if I understood right, what the Loadbuster does is to form a parallel circuit within itself so that when you open the fuse door, the contacts in the 'buster tube take the bront of the energy and the tube (plus if it has that special gas) arrests the arc while the contacts within separate. Right?
Were you down in the US after Super Storm Sandy? You guys from Canada really helped us out a lot after that storm rolled through! Very much appreciated, and really nice equipment! Your trucks made ours look like Shytt!
Greetings from Hungary! You have some interesting stuff on your channel, i work on the opposite end of the spectrum. (Im car elecftrician, EV's going to be a real pain in the rear because of the high voltage DC circuits.....)

Great channel. Thanks for the close up tutorial.
I recently started watching your videos. That’s a nice video, up close to see how it’s done. Watching from Eastern Ontario. Cheers dude stay safe
DUDE! Your channel is blowing up! Keep up the good work man, look forward to your videos all the time
Big fist bump. Watching front Scotland UK
Greetings from Nisula, Michigan 👊
Thanks to your videos I can look on power poles and understand what's there, like the transformer I was wondering why was there when there's no houses for a few miles around it is actually a voltage regulator.
Watching from sunny Syracuse, NY. Been curious about power distribution since a little arc-flash incident at work (Michigan, 1990's), where a couple cubic inches of copper (section of a 480v buss-bar) turned into plasma - a real attention getter.
new subscriber from the UK... awesome channel. Learning how you guys do stuff over there. I'm an LV guy so we don't do much over 415v (see a bit of 480 sometimes on split phase supplies but they're rare). but it's interesting to see 'how the other half' live.
Interesting thing about work here is that our fault currents on the LV network tend to be larger due to larger and fewer transformers (a typical unit here is 750kVA continuous rated 3ph 11,000 to 415/240v, close to the substation the LV side can have fault currents into the tens of kA.
Kudos to you ... stay safe
Guess I should have gone to work for the power company years back. Very interesting.
like the tool reviews, I'm from Va. and layed up your videos keep me occupied
Thanks! Sorry to hear your layed up tho, get well soon !💯🍻
👊🏻🤙🏼 from my couch!!!!! Great video man.
Thanks Brian! 👊🤙
Thank you for the insightful video. I am watching from Toronto, Ontario, Canada.
Thanks! I love Toronto ✌️👊
👊 Watching from the UK. Love your channel..! :)
👊👊
Nice presentation Sir, may I know the life span of the Loadbuster?
🤜 Kia Ora, subscribed and watching from Auckland, NZ. Great video, we use load busters alot on our network where we can and isolate the circuit if we can't use a load buster to open cut outs. Interesting how you say people asking why you look away, here in NZ, we are trained to look away when operating switches etc for exactly the reasons you explain. Stay safe out there everyone 😊
Another thing I would have liked to see is a continuity test before and after you break load. So you know it’s working properly.
👊 watching from Biloxi Mississippi USA
watching from Guyana, South america
Load buster sounds like a strip club lol. Great video Aaron
Haha I actually had a hilarious comment on the original video where buddy said this isn't what he expected when he clicked on the title
@@Bobsdecline Would have made a great click bait title for sure lol
On a few transformers around my neighborhood I've noticed a little incandescent light bulb on them. What are those for? Are they just an indicator to show that it is energized or is it connected to a thermostat that turns it on if the transformer is getting too hot?
🤜🏽 watching from western Massachusetts. Love your videos, super interesting! Thanks for what you do!
Thank you so much! ✌️👊
Love these vids here in Devon, England. Top stuff! 👊👊
When you say the inside of door is coated with material to snub out arc, does that mean a blown cutout should be swapped for new if that lining is degraded from previous break?
So if I understood right, what the Loadbuster does is to form a parallel circuit within itself so that when you open the fuse door, the contacts in the 'buster tube take the bront of the energy and the tube (plus if it has that special gas) arrests the arc while the contacts within separate. Right?
Were you down in the US after Super Storm Sandy? You guys from Canada really helped us out a lot after that storm rolled through! Very much appreciated, and really nice equipment! Your trucks made ours look like Shytt!
Great videos very informative. Watching from Moncton NB 👊
Thanks Jason! 👊👊✌️🇨🇦
Watching from Munich, Germany 👊
Greetings from Hungary!
You have some interesting stuff on your channel, i work on the opposite end of the spectrum. (Im car elecftrician, EV's going to be a real pain in the rear because of the high voltage DC circuits.....)
