I'm in! Mill City, Oregon USA. John Klein Always love what you do Aaron! Thanks for the demonstrational video! 👊👍Excited for my upcoming Lineman apprenticeship!!!:)
I'm in. I work on Category I-III and in my newest area of responsibility, having comfortable stuff instead of the 8cal/cm² coveralls that make me look like a flying squirrel would be awesome. Wichita, KS
I'm in - Texas. Fellow lineman that loves the technical aspect of our job. I appreciate that you go into depth with substation. My company has a separate department for substation (I work distribution only), so I'm really grateful you get to show us substation information.
I’m in, from Georgia USA. Protection Engineer for PoCo. Great to see this awesome channel shedding light on the details of what keeps the lights on in the MV and HV world. 👏🏻
I'm in, BC. Love these explanations - they certainly provide a lot more of the "why" than is usually covered which always annoyed me (rules are rules, but rules in isolation without context end up broken far more often - so explaining why a rule exists tends to give higher compliance). What seemed like a silly rule suddenly makes a lot more sense.
I love what you do Aaron. If I ever had the opportunity to change trades, I would go through lineman’s school and do line work. Hope all is well with you and your family.
I’m in, West Virginia, US. I’m a recent college grad and just started as an engineer for a utility company down in the states. Been subbed for a while and love your videos. I’ve learned a lot about the industry from you, and it’s cool to see things from a different company’s prospective!
I'm in, from Oregon. As an electrical engineer in an industrial faciality I really enjoy watching your videos. Hard to find info about substations, distribution and best practices so I always look forward to watching your content.
I’m in - Pennsylvania. I am a medium voltage electrician for a college. Our crew is rather small and is responsible for all overhead distribution, substations, and all the underground systems. I really watching your videos because we don’t get to work on much overhead distribution because 85% of our system is underground!!
Hi, in Northern MD here. We're working on a 115kV upgrade replacing lattice towers with weathered steel mono poles. 22 miles, two and a half year project. Your videos are informative and in plain english that most can understand. Your emphasis on safety really counts! Keep it up and work safe! 😀
I'm in - Florida. I especially enjoy the safety related aspects of your channel and have used them to educate my students in college studying to be LEOs, EMTs, and Medics about the hazards of electric lines at scenes.
I'm in, from Virginia. I wonder how many channel viewers appreciate the differences in systems covered by NFPA/NEC, vs IEEE C2, both incorporated into Federal and most states' laws? Or, how many other local, state, and Federal systems interact with grid siting and standards (especially around water crossings)?
Proper training and PPE. You can either use an insulated pole to work on the line that is long enough to avoid the potential for arcing, or work on one phase and stay in constant electrical contact with it. As long as you don't create an arc from line to line or line to ground, there's plenty of potential there but no flow of electricity as you're either working with a tool at the end of a long insulator, or you are at the same potential as the wire. Same thing with household current. As long as you're insulated from the earth, touching the hot wire will not shock you because you're not a current path. Touch both the hot and neutral/2 hot wires, or touch the hot while your body is at the same potential as ground, zap. Major difference is that the length of a possible arc increases with voltage, so the mad lads (and lasses) rely on the increased spacing of higher voltage transmission lines to not become a ball of plasma. I work on commercial/industrial electric after the transformer, and while I know why these things work, they still scare the hell out of me. A 480V arc on a conveyor panel is fireworks enough. I'm sure these fine utility workers can explain it better, but the main thing is to prevent the *flow* of current through your person. When you're working on one line, you and it are (ideally!) at the same voltage so there's no flow despite the potential for flow.
Thanks for the videos. I worked for BC Hydro for over 42 years before retiring . Interesting how the same work is done differently by different companies. I didn't actually work in the line trade directly . Involved helping the line crews install mobile subs and setting electrical protection equipment . We had mobile subs that are designed for 500KV and lower. Our subs all were set up for installation of mobile subs .
I’m In for South Carolina USA. But if chosen I’d like it donated to a rookie that can use a little extra boost of confidence that they can become a life long lineman
I'm in, helping launch rockets from Florida. Enjoy all your videos, but especially the substation videos to see how different utilities do things. Speaking of, what is the purpose of the dedicated neutral vs using the concentrics? I didn't see a neutral CT or anything to warrant the separate neutral, if you know? I've never came across that in my experience. The Knox stuff looks good! But, I don't see any ATPV / Cat or cal ratings listed on the website. I see the NFPA 2112, but without the ATPV rating I'm not sure if the shirts would qualify for the arc flash requirements for the electrical industry for outer wear. Still would make great undershirts if no ATPV rating. Stay safe.
@inothome Hey man, Your profile name came up in the draw! You can choose any item available @knox fr website. If you want to scroll up to the pinned post on the giveaway video, I'll edit in your name as the winner to confirm it's not a scambot. I've been communicating with the owner John on Instagram... I'll let him know your screen name. Do you use IG or Facebook where we can communicate further using direct messages?
@@Bobsdecline Sweet, thanks! Seems legit this time but I can't see the pinned post on a mobile device for some reason. I'll send an email to your YT email account.
I’m in, Utah USA IBEW local 57. I checked out the website & FR looks legit, as an estimator for linework & attending pre-bids onsite at substations you can never have too much PPE
I’m really curious Your take on all EV cars. Electric heat and so on. The grids now could never deal with the need of power required. As here in CA. Hot days PGE says don’t run AC units or there will be a brown out
In Mississippi it rained 7 inches in 9 hours the other day. Never saw pressure washing of transmission lines until i was in southern California where yearly rain is say 8 to 15 inches
That great and interesting. Was wondering do you have any UHVDC in your area and do you have any training for DC lines. I am in Boston NY ,US and on our west coast we have DC feed lines, easy to tell, just 2 lines instead of 3 or 2 groups of 3 . also can you show some time what a sub station does under large loads do to heatwave with so many AC running throw-out the community. a couple of substations buy me have capacitor bank and a reactor that switch in and out to correct lagging power factor. thank you for great video's
That crazy how you guys do that I couldn’t do your job I’d piss myself freaking out I’m going to get electrocuted lol thanks for sharing buddy Giveaway I’m In from Indiana USA
Just got home from work there's nothing like a good linesman video. Thank for getting my brain circulating and getting us learnt like Ricky from TPB would say. God Bless and safe working brother
Washing insulators energized is safe, as long as you follow the requirements. I used an Altec insulator washing rig and the guns had a special nozzle to break up the water stream, it also had 450 PSI at the gun and I forget the flow rate. Using two guns we'd go through 1100 gallons in about 25 min of operation. There was a minimum distance you needed to be to maintain enough clearance based on voltage to be sure the water couldn't conduct back to you. There are minimum water resistance requirements too that varies based on the voltage of the equipment. When using it on live 138kV the minimum resistivity was 900 Ohms/cm, if I remember correctly, it's been over ten years since I used it. The city water we had measured 1100 Ohm/cm, which was within spec, but to be extra safe we would get demineralized water a neighboring utility had for gas turbine generators (GE SPRINT System) and that water would measure greater than 20,000 Ohm/cm! They would have tanks with about 250,000 gallons or so of demineralized water that was processed from the city water. When washing you start at the bottom and go up quick to get it wet, then work your way back down cleaning it. In the substation we would use two guns at the same time from about 90 degrees from each other. Yeah, the first time you see someone do it you're like huh?? Then when you go and do it the first few times there is a little pucker factor. Any other questions? I've only used it in substations, not out on the lines. It wasn't fun, it's a real workout holding on to that gun! Glad the tank only held 1,100 gallons and it went quick.

We have some older 115KV subs with 3 insulator pin-caps now energized at 230KV (old idea from engineering long ago). Someone figured that 3 insulators would hold 230KV but just has less overvoltage tolerance. I do not recommend. We have had some failures. Trying to replace now with new construction and proper post insulators.
IM IN!!! I’m from Millbury MA USA currently working for my local utility National Grid and hopefully should going to the field as a apprentice lineman in October!
Can you recommend a good study guide to help with studying and preparing for classes, I'm thinking about submitting a application with GA power or FL power
I'm in. Indiana, USA. Our 138 KV feeders come in, I guess Delta, ungrounded. I've never really understood the particulars on equipotential grounding. Typically, a system is purposely grounded at the distribution transformers (on the low side) to provide a neutral to the customers on our mostly underground grid. What if the high side grounds? In 480 systems you would get a weird "red leg delta" situation but the OCPD wouldn't trip until the second short to ground occurred. If we get a line down in the 138 yard, does it short the system and trip a breaker or energize everything and everybody to 138?
I collect insulators, and so I learned a few years ago from my buddies on the insulator collectors web page on Facebook that on the post tie stacks, you can count the number of fins, or skirts below the post tie biscuit to know the voltage. For example, a Lapp 25D1 stack has 4 skirts and rated for 25KV max. And a 35KV unit has 6 skirts.

I'm in, Illinois Knox Fleece FR Hoodie Blue/Gray Certified welder here and I love watching your content. Always been fascinated by the grid system. Love it!
Around here counting the insulators would help little. Anything running at less than 115kV is upgraded to 115kV by all utilities in the area. There are several lower voltages in use, and by upgrading to 115kV, inter-utility connections become possible. The area has a real patchwork of utilities, and by inter-connecting, reliability can be greatly increased.

I'm in. Indiana, USA. Our 138 KV feeders come in, I guess Delta, ungrounded. I've never really understood the particulars on equipotential grounding. Typically, a system is purposely grounded at the distribution transformers (on the low side) to provide a neutral to the customers on our mostly underground grid. What if the high side grounds? In 480 systems you would get a weird "red leg delta" situation but the OCPD wouldn't trip until the second short to ground occurred. If we get a line down in the 138 yard, does it short the system and trip a breaker or energize everything and everybody to 138?
I collect insulators, and so I learned a few years ago from my buddies on the insulator collectors web page on Facebook that on the post tie stacks, you can count the number of fins, or skirts below the post tie biscuit to know the voltage.

There are several lower voltages in use, and by upgrading to 115kV, inter-utility connections become possible. The area has a real patchwork of utilities, and by inter-connecting, reliability can be greatly increased.
