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.

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?

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.

Appreciate the comments very much! 🙏🤝

Now we know what company he works for. Guy dropped the ball eh

@@linehandibew6205 I've known what company he works for for years it isn't a big deal people knowing he just doesn't advertise it . He works on the east coast of Canada it isn't hard to figure out lol

@@apollorobb it’s messing around because he blurs it out in every video

@@linehandibew6205 the issue isn't knowing what company he works for the issue is showing the logo in a video of something terrible happening and people associating the two

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... kzfaq.info/get/bejne/jNiJks6Q1crQc6c.html

Amen. Bonding and grounding are not the same thing!

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".

If you have windstorms, why aren't they installing an underwater line?

Thanks Matt! Cheers!

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.

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.

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.

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 great advice.

@@potatolew4495 , we need people in this industry ,it is drying up fast. for those that do get into this line of work, they will never be without a job, or have to deal with starvation wages. thanks for the reply!!!!( retired "IBEW" member)

@@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.
