Using the 25kv Loadbuster

*EDIT* Just posted this a couple hours ago ... it hit 5k views then crashed :( The video was showing an error and wouldn't play anymore ... lost every single comment! Had a few really good ones where some viewers explained exactly how SF6 gas worked. I'm going to keep working at trying to get the first post back and retrieve those comments, but it isn't looking very promising :( ******* Hope everyone had a great weekend! I create these videos for 2 reasons - to give the general public a more in depth look at our trade and how the power grid functions. - to help educate and exchange ideas with those within the trade that are properly trained and authorized to work on powerlines and related equipment. After seeing a few discussions I just want to clarify that these are NOT d.i.y videos for Mr. Fixxer upper! Cheers all! 🍻

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"

I'm not a lineman but I enjoy your videos. I'm from Independence MO

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.

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!

Anyone else getting the 'slap chop' advert. Love this guy.

I recently just found this channel, always been fascinated with electricity since I was a kid, and it's cool to see the high voltage side of things.

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.

Hi! I'm watching from Buenos Aires, Argentina! Thanks for all this information!

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

Thanks for educating the public on how our infrastructure works and how much skill is needed to operate and maintain it.

Great video, I wasn't sure how a load buster worked but it makes perfect sense now.

I'm just a retired handyman but I love this type of content.

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!

I learned alot 👊👊 now I know what Con Ed Does on my POLE. Cortlandt Manor NY, USA

Frig'n awesome demo! I always wondered what the door and tube looks like up close.

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.

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.

Greetings from cedar hill texas. Well done videos. Thanks! Retired from Bell Telephone, always admired the guys in the big trucks, standing in the rain, opening switches, wondering about all the techniques and equipments they used. Your videos are very informative. I will skip the lame jokes about I didnt have the potential to be a power company lineman......be safe always and see you on the channel.

I like seeing the tools of the line man! Great video.
