In many ways, the grid is a one-size-fits-all system – a gigantic machine to which we all connect spinning in perfect synchrony across, in some cases, an entire continent. On the other hand, our electricity needs, including when we need it, how much we need, and how reliably it should be delivered vary widely. Substations play a critical role in controlling and protecting the power grid.

Are you an INTJ?
Informative 👍🏻
I remember when I was 15 (long,long ago) half of the North Island in New Zealand was blacked out after a transformer fault at a substation in Taupo. The only light was from places that had back-up diesel generators like the hospital. I rode my bicycle around town (had the old dynamo headlight) and it is amazing just how dark it was. Power came back on about 4 hours later.

You mention about halfway through that the pylons (towers) hold the cables high up to avoid electrocution risks. While this may well be the case I was under the impression it was to reduce transmission line capacitance and therefore increase efficiency overall?
Me too I'm fascinated with medium and high voltage line and substations, I'm interested in them since I was a little kid and I always liked the sight of a row of poles carrying conductors thru the countryside, and the intricate wiring and all the equipment of a substation.
Where I live the power utilities are burying most of the old MV/HV lines between 16 and 50 kV (sometimes the ones with higher voltages as well) and replacing a lot of the common open-air substations with GIS (gas insulated) ones. While this for sure is an advantage for the efficiency and reliability of the electrical system and for the environment it's a bit of a shame for me as an electrical engineering enthusiast, because a lot of the stuff that I liked to see is disappearing.
Question, after reading a lot on EMPs and other catastrophic grid failures. it's always said that transformers can take 6+ months to manufacture, but you say they're extremely simple devices, Why is the manufacturing process so tedious?
Interesting video but a minor quibble: could you please slow down your delivery to make the words clearer.
Look up " skin effect" of conductors…
Very interesting.
To better appreciate where your power comes from, build a solar system (even if it consists of one panel and a car battery) then challenge yourself to power something with the solar system and only the solar system for a week or 2
I run my whole house on batteries and solar panels, and if there's even a few amps unaccounted for, I can usually see where they are going (for better or worse) same with voltage, if the battery voltage is low, I know the mains voltage won't be far behind, if the PV voltage is high, it means the batteries are full and I'm not using the excess power, if the PV voltage is low despite full sunlight, and the battery voltage isn't going up, and the mains voltage is low, it usually means my wife is using the hair dryer while making coffee (overloaded inverter)
When you generate your own power, you effectively make your own energy grid (complete with generation, transmission, and conversion) and you can apply that knowledge to the actual power grid (to a degree anyway) to visualise the power going from the generator to your wall socket
Wonderful video; thank you.
EMP?
It’s like a massive circuit board
At 10:49 is that supposed to look like two people handing something off to each other?
Thank you! I have an interview tomorrow for a Transmission and Distribution Engineering position, and as a senior in college studying electrical engineering this helped me to review.
Slice meats, lettuce, slap on bread, mayo, serve. That's how.
I just learned a lot in 12 minutes, thank you.
Far away? I live within 5 miles of 4 power generators.
Interesting but i would like way more specific engineering concepts and applications please.
Video! Thank you for producing it. Very informative and easy to understand. Visual aids speak 1000 words.
Great video… 'cept for the obligatory and unnecessary lecture about global warming at the end. Fault encountered.
Nice video. Right up until you brought up the global warming hoax. Thumbs down and no sub for pushing discredited science. I'm out.
A substation looks like a fun place to play around and climb things.
Mini Mike can't even take on Liz Warren in a debate.
1:54 thank you mr. infrastructure tourist.
2:10 nice old building and new technology!
10:50 nice art! where is it?
At 03:58, high heels in a substation compound?
