I like to find one of those.

Good catch on the Atlas explosives. At first they looked like they were in good shape until you showed the goop. I am sure that part of your video got the ATF's attention. While nobody is likely to find that case, that's a 'no no'.

Thank you very much for this presentation, very much appreciated 👌

looking good!

careful

wow that's crazy! I'm stoked! 💪👍

What an absolute fantastic walk through video. It’s always been my dream to have someone talk me through substation equipment in real life. This is about as close as it can get. Cannot thank you enough. You got yourself a new subscriber!

you know those NM underground mines were never properly deconaminated/contained and still contain levels or uranium

I seen an extra head gasket hanging off the rafters. Great OWS engine.

Looks like the same one the 86 year old man started. Nice

Had to watch again. Not many can do that at 86. Most are in the nursing home or 6 feet under.

What company do you work for?

Where is this Sub located at ?

Really want to join you on a mine exploration!!! Idk how to reach put to you otherwise but if we could message somehow that would be awesome!!! Spamming this in hopes you see one, sorry.

I would totally push the Green button to start. I am so use to Green to go, Red for stop…

So im guessing this means that plant that we've been watching is finally online

Why are they closing in several breakers with failed trip coils?

Absolutely fascinating, thank you very much.👍

Thanks for the video. I worked in a mining/milling operation years ago. 600 volts max. Thanks again.

Here in Germany and Europe altogether every official shits his pants when you talk about flying drones close to substations or power lines... like a single small drone will surely cause a nation-wide power outage if it collides with a single power line.

With regards to power factor control, I have a good example of how this works based on a 120v. electric motor. This is a 2 hp motor that draws 12 amps line current with no load. By parallel connection of a 180 uf capacitor, my line amperage drops to about 3A. The capacitor cancels the inductive portion of the current drawn from the AC line by the motor.

What is the loss like ?

Can you please tell me how to calculate, the fuses in the primary for a transformer 600 volts, 3 phases, 75 KVA? Primary Delta and secondary Why. Thanks.

Is this in mogollon?

Are you a superintendent or engineer?

As a part-time student of Electrical & Electronics Engineering, I have t three QUESTIONS Please. (1) Why are the Transformers "Humming" if there is no load on them? (2) Is it periodically required to change the Transformer Oil like the Motor Oil in an Automotive Engine Crankcase? May I assume Probably NOT since there is Normally NO Combustion? (3) What kind of Oil is required if it is Necessary to change the Transformer Oil?

20:45 cool stuff but unless its calibrated and maintained kind a useless. Just more alarms that people will lift and leave out of service. Send oil samples into a lab. Much better off then guessing if your sampling equipment is correct or not. I wouldn't be using that for tripping.

13:44 Why blur the operator?

10:02 top right. Do not put shorting terminal blocks in any PT box. Those should be only used in CTs. Someone will put shorting screws in their and blow the ccvt up. Not sure if thats before or after the fuses in there or what but just don't do it. Ask me how I know. Don't tell people to use a screw to hold a sticky back. Rather not have another hole, someone will put a screw in the top. 10yrs no one will care if that sticky back is there. Just make sure you leave enough tail and mark your cables really well. Still doing maintenance on equipment from the 70s.

Thank you, that was a treat. This is how retired EEs get their kicks!

What Ores or Minerals were being Mined in this Mine Please?

Curious QUESTION -- What is the likelihood of a Drone flying into a Switch, Transformer or other Device and causing "Arcing, Sparking & Shorts?" Is a Drone Safe to operate in the close Vicinity of a Substation?"

When there is a set direction of power flow, the normal for a transformer will primary will be delta and the secondary will be wye. The wye connection on the secondary establishes the system ground point. With a conventional power plant, the generator will be wye connected, and the step up will be delta low, wye high. Distribution transformers will have delta high, wye low. Because wind turbine substations work both directions, they need to have a wye connection on both sides. As a generator source on the HV system, the high side needs to be grounded. The low needs a ground, as the wind turbine is usually a 3 wire source. The purpose of the delta tertiary is to establish the ground reference. Since the delta is connected start to finish all the way around the triangle, the sum of VAN, VBN and VCN is forced to be zero. The moment the voltage tries to change, a current will flow in the delta and re-establish the balance.

Great video, thanks. I'm surprised you don't have a line ground switch.

What makes huge transformers better than multiple smaller ones? When I see roads closed to facilitate their transport, I can only imagine the expense.

Next chance you get, putting in another of these facilities I'd LOVE to the ground system being put in!

Great tour! About the SF6 gas, it's more of a greenhouse gas, not as much ozone depleting. It's about 24,000 times more potent as a greenhouse gas than CO2. The new gas is about 1/10 as potent as SF6 and doesn't last long in the environment.

Nice video dude! Not a big fan of the mechanical lugs, and am surprised to see them all over this collector substation! Is that common for wherever you live?

So when you have a delta input or output you have to ground one of the phases right? (as in Tn-c-s) Do you have any ideia how high the primary/secondary can float in relation to ground if this connection to ground is lost, and would this charge be mostly capacitive coupling from pri/sec or electrostatic charge picked from the lines? Thank you.

What an interesting and informative video. Looking forward to a future video of when the station is livened up but I bet you won't be filming quite as close! 😀

That's a clean yard! I'm trying to become a sub tech, hope to work on similar equipment someday.

Please, when it starts, you have to show us...

Thanks for the video, fascinating stuff. All the best.

Molecular nitrogen gas has a mass 28 g/mole, while molecular oxygen has a mass of 32 g/mole. Have you ever asked yourself why you can breathe if all the oxygen has sunk to floor? It is because the collision frequency between different gasses is so high that they cannot settle and be stratified by gravity. They continuously collide with each other and mix together. If I measure at the floor, each volume of gas will contain 78% N2, 21% O2, about 1% Ar, and 0.04% CO2. If I stand up I will find the same proportions. If climb mount Everest, there is less total air, but the proportion of these chemically stable elements is the same. In fact I can travel to the edge of space at 80 km, where the gas density is extremely low, but there will still be the same proportions of N2, O2, Ar, and CO2. SF6, like these other species, does not readily react chemically so that it is stable. It then mixes with other gases and maintains its proportion, albeit a small proportion, throughout the atmosphere.

I enjoyed watching and learning from that, thank you!
