Applications are opening soon... Does anybody know how exciting that is?

Gettin in shape! Gettin healthy! The Losers are gone for good! What more could a guy ask for? Shoooot! Lol Linework! Yahoo!

Aaron, Ive watched this video 10 times this morning...

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 .

Well Dang i had a hand full of wire nuts and was gonna rewire my 25KVA 2 pot system DOH !!!

I'm gonna start work with load buster in 2 weeks, thanks for your advice

👊

I am south of you in peculiar

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.

We cant do this all day

Too cool! First time hearing from Buenos Aires! 👊👊

Cheers Idaho! 👊

Udaho

@@Bobsdecline Same, watching in Idaho

Thanks Ron! I try my best to share information that's useful for everyone! Cheers!

Awesome! 👊

Thanks man ! ,🇨🇦👊

Hey! Thanks for taking the time write some feedback! 👊

Best lineman page out there. Most Informative and best content

Greetings! 👊👊

Thanks Dominic! 👊🇨🇦🇺🇲

First time I've noticed a comment from Lima, very cool. Cheers!

@@Bobsdecline cheers mate

Hahha it was getting soo long! ... And this weather was way too hot for long hair 🤣. Glad you didn't get a flash! Stay safe my friend!

Challenges keeps ya on your toes! Yes we do the same (when breaking parallels) it's a very good practice... Thanks Greg! 👊👊

Difference in load can draw an arc. We do the same here in New York.

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?

👊👊🍻 Cheers to Northern California!

Thanks! I love Toronto ✌️👊

Thanks Jessie! 👊

Cheers!

👊👊

Thanks Brian! 👊🤙

Thank you so much! ✌️👊

Thanks Jon! 👊👊 I did see a comment from yea earlier, must have been on the original post that crashed? Thanks for taking the time to write again!

SA transplant in Austin now.

👊👊

Thanks! Sorry to hear your layed up tho, get well soon !💯🍻

Nice! 👊

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.

Lol Thanks man! The first video crashed, then KZfaq wouldn't let me re-upload it because it was a duplicate 🤦‍♂️ had to make some adjustments in order get the video back up!

Thanks Jason! 👊👊✌️🇨🇦
