Not gonna lie, there's just something sexy and exciting about old school meters, gauges, buttons, switches and knobs that no GUI on a computer screen can ever truly replicate.

[@Physicsduck]

This person gets it. :) We call it "Old School Cool".

[@fredinit]

I prefer analog to digital... With analog, after using the panel for a while, you can just glance at it to see if everything is were it's supposed to be at. That pointer should be pointing that way, this other one next to that line, etc. With digital, you have to mentally decode the values and some of them can trip you up in a scary way... It is supposed to be a 9 or a 6? Or 8 versus 0. There is a place for digital - when you have to know what the value is, not where the pointer should be. My iWatch has an analog face.

[@kindlin]

@@fredinit I was entirely confused by your post until you started comparing individual digits. Just because something is digital, does not mean it needs to show numerical digits. You can put a dial gauge on a screen just as easy as a value read-out. And then, if you ever need a more precise value for whatever reason, the digital information, in precise digital representation, will be displayed below/next to/inside of the dial. Or, at least, it should be this way. I recognize it's often not, but that's a design decision, not a limitation of digital information.

[@Idrinklight44]

I have to agree!!! Flew on old S-58 helos, to myself the cockpits are sexy

[@michaelknight4041]

​@@kindlinthere are places where each one has its advantages. For instance sometimes its still nice to have the needle movement of an analog meter like when troubleshooting an oscillator. Its much more intuitive to see a meter sweeping back and forth than a bunch of digits flashing. But like I said each one has its merits

[@ComfyWombat]

My old man (RIP) was a Navy Electrician in the Royal Australian Navy, and I have heard fun tales of ship generators being dropped 180Deg out of phase when hooking up to shore power. Shore power wins, and a generator spinning clockwise becomes a motor going ANTI clockwise... for about a microsecond, before the generator drive shaft snaps, the mounts rip and the generator is launched through three decks, and onto pier next to the ship.

[@Physicsduck]

That had to be one hell of a show.

[@steviebboy69]

[@yuglesstube]

Interesting!

[@greywolf271]

I would wonder how accurate those tales are. RAN boats at least from the early '60s had load-shed protection in the power supply circuits. They would also have been the best engineered power units at the time. Synchroscopes have existed for decades and were present in the '60s. I have worked in power generation plant rooms with late '50s equipment and load shedding was present even then. You cannot physically connect an incoming source to a mismatched alternator.

From a "knowledge per unit of time" perspective, that was the best damn description of power factor I have ever heard. I don't watch KZbin shorts because of reasons, but I think that part would make a very educational short.

[@Physicsduck]

Thank you! I really appreciate that! I tried to make it a short, but couldn't fit enough of it into the 1-minute timeframe for it to still make sense like I wanted it to. There's just too much setup required. I could do it with animation, but I'm not that good an animator. Perhaps I'll take another crack at this when my skills have improved a bit.

I would love to see more about a black start condition. There is a black start power plant about a mile and a half from my house.

[@janisvaskevics93]

About the amperage - 3 phase power formula is P=√3*U*I*PF which in this case would make it P=√3*2440*46*1=194405W=194.405kW That is, if I see the meters in video right. Still, I took readings from different times in video, so it cannot be considered exact result.

[@Physicsduck]

Now THAT is an excellent comment :) Thank you! There's a shot in there that shows the entire panel all at once so that all the readings match up in relation to time. That way people can check their math and be sure they got it right. :)

[@ThePoxun]

In the UK is becuase our grid completely covers the country in a single synchronous AC system and the frequency is constantly monitored and recorded you can, with a bit of analysis, use the variations in background mains hum on an audio recording of sufficient length to timestamp that recording to the second.

[@SeanBZA]

Only problem with that is that this is almost completely obliterated by the variation in timing of the recorder itself, from things like battery voltage drift affecting the crystal oscillator that provides a sample clock, to temperaure drift as well that make it vary. You get more of a graph of oscillator drift with time, and with analogue tape, with wow and flutter, it is even worse. Digital the hum is hard to recover, mostly because most recorders will absolutely actively remove 50/60/100/120Hz noise with narrowband filters in the DSP engine that does the pre encoding processing, simply to reduce data use recording hum, and then your typical Frauenhof encvoding to MP3, FLAC or even AAC, will strip out all the bass noise to a great extent, unless not masked by other sound energy, so the recording will have very little data to begin with. Even if you were recording using WAV or other lossless CODEC, the data stream would have very little hum imposed on it, and if recorded off a phone line, with all the equipment along the way adding in hum, and the SPEEX codec doing serious decimation to get all this data into a single 8kbs data packet system, you will be hard pressed to get anything. You can do it in theory, but need both a good recording, no digital to analogue conversions until the final ADC to record, a log recording using a very well disciplined ADC clock, preferably a Rubidium disciplined one, though an ovenised crystal that has been running for 1000 hours continuously is a close second, and really good dynamic range to be able to use DSP to do the narrow band filtering needed to remove all the rest. Yes there is a paper, but it is idealised, and real life is hard to actually implement.

[@stongeification]

Thats just like... Marco Reps levels of zeros right there

[@ThePoxun]

I didn't say it was easy 😀 I did kind of gloss over that with "a bit of analysis" which should have been a "complex piece of analysis requiring looking for a best fit taking into account variances in the recording fidelity". It doesn't always work and yes modern digital recording filters can make it harder but still often record harmonics that are usable with the right analysis. Tom Scott did a video a few years ago.

[@steviebboy69]

[@felixyasnopolski8571]

@@SeanBZA There's not such a big of the problem. What you need to measure from recording is the frequency fluctuations, and since they are relative - you can find the correlation between your fluctuations and grid fluctuations.

Two panels that will keep you staring for hours are the old slate-backed panel in the Worthington generator shed at the Buckley Old Engine Show (now disconnected but AIP for your staring edification) and the DC knife switch panels for the old steam DC plant in the basement of the New Yorker hotel. Which I saw a video of ONCE and never found again. Skinner Una-Flow engines. Pretty sexy.

[@Physicsduck]

There's a couple of the old slate panels still in use out here in the wild. I'm trying very hard to be able to get some video of them, but the security guys have a problem with that. They DO exist though, and they're STILL IN SERVICE!

[@FuncleChuck]

Hearing you scream about kilowatt-hours is fantastic. What an absolutely cursed unit. Our new electric car rates its efficiency in MPGe, or "Miles per gallon equivalent", with is based on miles per kilowatt-hour... and my brain nearly malfunctions any time I try to determine what that actually means.

[@theWONDERFULwiz]

Honest question - why is it bad? I'm no EE or anything but I have actually always been irritated by some of the other alternatives like Amp-hours for battery packs. In that context I think watt-hours is much more useful than amp-hours, right? What am I missing?

[@bragesb]

I don't really get it either, but it may have to do with the fact that the Watt is defined as 1 Joule per second? So 1kWh is just one thousand Joules per second times 3600 seconds, and the units cancel out and leave you with 3.6 million Joules. Which is all fine and good, but the Joule is a very small unit for measuring the energy consumption of an average household, whereas a kWh is about the energy an average household uses in an hour according to this video, so it makes sense to me that that would be the more popular unit here

[@deelowe3]

​@@theWONDERFULwizbecause we already have a unit to measure power over time. It's called the joule.

[@drheaddamage]

No, there's one worse: the kWh/year unit. used to indicate power consumption over an average year. Now you're mixing three time magnitudes!!!

[@CKidder80]

I too hate the kWh unit. It's truly cursed. My biggest beef with it is using it in reference to electric cars and charging. You see, your car might have a 70kWh battery in it. Your charger might be 10kW. So, How fast does it charge? 10kWh per.... hour... um... So it returns 10kWh of battery capacity per hour. Yeah... having "hour" as part of your actual unit is terrible. I think joules would be the better unit, as others have said. Or, maybe megajoules for battery packs. Alas, we are standardized with kWh for both batteries and the grid. I hate it.

[@BrightBlueJim]

In another life I was a radar technician at a remote station on the Alaskan Peninsula that was of course not on any grid. It was powered by five 300kW White-Worthington vapor-phase cooled diesels, which were also the heating plant for the site. I made friends with the power plant operators so I could watch from within the control room when they did fun things. Usually it took only two of the generators to power everything, but under some conditions they had three on line. This brings back memories.

[@transientvoltage]

Your intro describes me well, as a kid I loved playing with knobs, buttons, switches and sliders. The sound equipment at RadioShack was a favorite.

[@n1gak]

200 kW / 2400 volt / sqrt(3) (because the ammeter is measuring one leg); = "just over 48A" which is what the meter shows. There would be a further error (which will be difficult to read given the scale of the instruments) where POWER could be different than kV * A because of non-unity power-factor.

[@jfbeam]

Plus, the phases are never balanced. (the enduring problem of every power company. I pay attention to it in the data center, but there's not much I can do about it.)

Chris in my old company (pre solar) in Australia for planning for new subdivisions we allocated 4 kva per house for areas that also have gas for water heating and cooking areas without gas 7 kva per house. Being a 240 / 415 volt system we can run long and large LV distributors and much larger distrubution transformers and much less of them than American 120 240 lv . Usually that equated to transformers of 500kva so 120 houses for gas areas 75 roughly for all electric subdivisions per transformer .

[@Blazer556]

This is my first comment on a KZbin video. Love the channel! I’m in the software engineering space now but at one point I was a maintenance electrician and had a little exposure to power generation. This answer may have already been proposed so forgive me if I’m duplicating it. I think the meter readings can be explained by real and reactive power. A large chunk of the loads on the grid are inductors and when your AC load is “too inductive” or “too capacitive” reactance starts to come in to play. The meters show real power. But the generator has to work hard enough for real + reactive power. I think utilities have large capacitor banks to account for this. A quick google shows the math for this. If you assume 60Hz AC the math is really simple but if you drop that assumption, time to bust out the calculus.

How could I ever actually make it worthwhile to spend so much time, effort, and money making videos that nobody will ever want to watch? My reputation is torched, and I'll never get any kind of sponsor support to fund this, it's all on my head. So to put this out there and see that people actually like it, and to see that someone with your perspective and experience truly gets it and thinks so highly of it........that's the whole ballgame, right there. Fifteen years I've been on this platform, thousands of videos published, and god only knows how many comments I've read. I've read comments that made me thankful, that have made me angry, and that have made me laugh. Yours is the first one that made me cry. Thank you, from my soul and with all of my heart, thank you. cb

I’ve run multiple large Michigan data centers. We have lots of blinking lights, meters, generators, and cool looking stuff.

Saw a clip from this video on tiktok, glad I found the youtube channel! I love the format. Subscribed, look forward to binging later.

[@Physicsduck]

THANK YOU FOR BEING HERE! If you see my video on TikTok please let me know where. I don't HAVE a TikTok (at least, yet....perhaps I should?). So that means someone stole my video.

[@Jakeamura]

As a mechanical engineer who’s worked in the electrical/power distribution service industry for 10 years I appreciate your content. I never get tired of visiting power plants and learning about their controls and processes. My favorite part is just seeing the vintage equipment that they have. Abandoned in place is a nice acronym. My whole world revolves around this type of equipment and keeping the old stuff going in some capacity or another (relay replacements, generator circuit breaker replacements, general switchgear bus/insulation replacement etc). It’s cool seeing you all still operating with all the old school tech!

[@dieseldork6]

Awesome video! Thank you for sharing!

[@ZGryphon]

I don't know if any of it is still there, since I haven't visited the campus in decades, but when I was at WPI in the early '90s, the ground-floor lobby of Atwater Kent Laboratories (the electrical engineering building) was dominated by an enormous antique electrical control panel. It looked like the kind of thing a person would use to resurrect Boris Karloff, all humongous knife switches and big Bakelite knobs. Quite possibly the coolest thing on campus, and that was at a time when WPI still had a nuclear reactor. :)

Respect to the dude. I learn something every video I watch. Short and sweet.

niceeeee, i was sad when i found your channel a year ago or so going through you r entire catalog of videos and sad it ended, glad to see your back! you get a sub from me!

[@Physicsduck]

THANK YOU FOR THE SUB! :) It was a rough ride, but now that I've been to the bottom I can teach people which way is up. :)

[@DrakeLuce]

Really detailed, exactly what I want to hear about, love it. Digging this format and I'm locked in for your next videos Chris

[@Physicsduck]

That's awesome! Thank you! :) I was worried about making such a radical change in format and I'm really glad you're enjoying them! :)

[@Mjsmith1029]

welcome back Cap. Missed you. Glade to see you back.

[@jpulley]

I've worked in a coal fired power plant for 14 years. In the last year I've been trained to control operator. Our plant is 580 megawatts. These videos are very informative. Ive a lot of these gauge and heard of lot of these terms before. But these videos are kind of a deep dive into some of these topics.

[@JanuszS-zm5om]

Hey, good to hear You are back! Cheers!

[@Kataang101]

These people make the world go round

[@sorarjom]

The video was fun and educational. The disclaimer was long, wordy, funny and must have taken a bit of time to put together, worth the read once, but only once.

[@sortoftubular]

I designed and had built 3 synchronizing panels almost exactly like yours for 3 generators at my GE plant. Of course, I used the same model GE meters and switches.

[@Physicsduck]

That's cool! Now I'm out here trying to find the same gauges to match, lol.

[@Jeagles]

I took the time to read The Disclaimer and I think Chris might now own my soul.

Absolutely love these videos. Shorts are awesome too.

Hey I was thinking about your channel a few days ago, nice to see you upload!

Check the Shorts section on here. I've been slowly ramping up making videos for a few weeks. and THANK YOU FOR STILL BEING HERE! :) I appreciate you, and your patience :)

[@bryanduffy4259]

Would like to see a video discussing the control logic the plc uses to keep the system running automatically.

[@aaronatstate]

V x A = W is only for DC circuits. AC changes things

[@jeffl4810]

Still stands. It's just the simplified version of V * A * cos (theta) = P For DC, the trig function simplifies to 1, reducing to V*A=P Edit: Note: Power Factor, or PF is just the calculated term of cos(theta). As DC can/is considered, in engineering terms, AC with an infinite cycle period (0 hertz). So it can be considered the voltage waveform is perfectly in phase with the current waveform. Therefore, the current voltage phase relationship has a 0 deg phase shift. Cos 0 = 1, and why the equation simplifies to V × A = P for DC.

[@jfbeam]

Exactly. It's AC. And AC is "voodoo". (there are three phases, and differences in voltage vs. current vs. phase - thus "power factor")

[@Graham_Wideman]

@@jeffl4810 I think the formula you want is Active Power [W] = V * A * PF where PF is cos(phi), phi is the lead or lag angle between voltage and current. Taking the cos function of PF doesn't make sense as PF is not an angle, it's a ratio.

[@jeffl4810]

@Graham_Wideman the angle is the phase relationship of the voltage (hopefully) sine wave, vs the current sine wave. A lot of ratings simplify the phase relationship by denoting it PF, which is just a factor to multiply by, of the results from the original COS(theta) term If the current is ahead of the voltage waveform, it's called leading, (cos-90 for purely capacitive) and caused by capacitive loads. Lagging is behind, and is caused by inductive loading (cos90 for purely inductive). Purely resistive is perfectly "in phase", and has a cos0=1 relationship. In reality, the theta will be between -90 and 90. The further away from 0 it is, the more "appernt" or "imaginary" power is flowing vs "Real" power. There are many other things, like mechanical loading being one, that affects power factor. Pretty much every electrical device other than old skool light bulbs and resistive heating elements (and even those often have phase controlled output mucking with power factor) has an imperfect power factor. Many loads are now required to have power factor correction circuitry in their power supplies to make the load appear as if it's resistive!

[@jeffl4810]

@jfbeam Haha. No magic involved. But it can get weird. Complex numbers (ie sqrt (-1) ) have a practical use when calculating this stuff. It's actually kinda interesting

Thank you! I'm glad you're getting something out of this! :) Stay curious! and thank you for being here! You're the most important part of all of this!
