How we tap on 69kv/138kv live lines - energizing mobile sub

[@ianmyers1593]

I'm in Ohio, most of our 138Kv & 69Kv subs have a dedicated pole w/ cut outs for the mobile rig. Makes tapping up the primary easy and safe.

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!!

[@eldenrivas7842]

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.

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! 😀

Every video you make is an education about the electrical system most folks take for granted, until of course, the power goes out.

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.

[@kamloopscruiser874]

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 .

[@Diya6587]

For a live line work, what are the safety procedures to keep safe while working on those energized wire?

[@chadhardwick9214]

Don't die 🤘🏻

[@kdawson020279]

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.

I use to build substation stands for the 27kv/15kv sectionalizer and would build the switches with arrestor brackets and arrestors and wire it all up to the junction box and test it with the control cabinet. Kinda of neat to see some of the things I do out in the field.

Also, super curious. I’ve witnessed my local PUC powerwashing insulators from the built-up road salt. Do you have any insight? Much love from Ontario.

[@inothome]

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.

This is fascinating. I have never thought about amperage at a sub-station before. 80 Amps at 12 volts in my car and it likely won’t start, at least not on a cold day. 80 Amps into my house and I likely would not be able to power up everything (as I have a 200 amp service). But 80 Amps on each leg of a sub-station at high voltage and you can power a whole area. Thanks for making this video, it’s very informative.
