"This rectifier set can do a million watts, and this rectifier set can do a million volts"
Now we're talking baby
I'm still waiting for news re: the neighbor's dog. ⚡🐕⚡ 😉
My wife wouldn't even watch this video... or any part of it. EVEN though I told her I used to USE mercury vapor rectifiers. Ye gods. LOL de KQ2E
I can smell the carpet already...
Incredible thing. Mesmerizing. What sort of equipment might that have been used in? Any concern for X-ray production?
Remember the last time we seen one at college in 1979 in electrical power was the last year they were demonstrated

You bring back memories from my shipyard/engine building days in the 70's. we had six or seven of those bad boys supplying 220v DC to the overhead cranes. One morning when the outside temperature was below -10degrees celcius there was no power to the cranes. My solution, play a gas fired space heater across the length of the array of tubes until the mercury vapour was warmed enough to strike an arc. The Director asked me why there were no cranes operating. Electricity is frozen I told him. Called me a stupid boy, but I knew better, after half an hour of gentle warming they, one by one, fired up into full operation. Happy days, thanks for bringing it all back.
Frozen electricity, thats a good one. Well done for you understanding of Physics I hope the Mgr thanked you. Boris Karloff films often had MAR's and big neon discharge lamps, very spooky.
That's hilarious, good work

Who else is overjoyed at the fact this legend has started to upload again, as I know I am
Ya! Super happy haha dude is a legend
He is awesome science teacher but a good one
Im super hyped 17 mins ago i rush to youtube idc if my noodle get burn (jk)

Old intro? Ahh yes. The nostalgia.
This is the best intro. He should use until the end of times
Oh how I missed that intro. The beat makes me smile ☺
Hearing that in a new video, even better.

I was disappointed when the old intro wasn't used, as it brings back so many good memories of madness. So it's great to hear it again
It's terrifying to think that touching anything live in that room could kill you
This type of Rectifier was used in Melbourne Australia to produce 1500V DC for the Electric trains , there were 7 of these H&H glass bulb rectifiers across the network in 1970's the last was de-commissioned in 1981 . There were large fans below each bank of 4 bulbs and as the load increased on the rectifier unit the fans speed increased till it reached maximum speed . It was an extremely noisy environment that was extremely hot in the summer but nicely warm in the winter.
if ever there was a dangerous device these has it all , if they ever broke mercury finished up on the floor and every where it was quite a job to transport them with special crates, it took 3 people to hold and slowly invert the bulb while the pool of mercury was also inverted.
It was quite spectacular to see but by today's standards very hazardous I was glad to see the last of them .
Railway substation had Rectifier units made up of a Transformer with an output of 12 single phase's connected to a bank of 4 bulbs and a large 12"fuse each phase along with associated protection relays in the Rectifier control cubical (64, 64A, 86, 86X, 30 ) . I also remember two large extraction fans for cooling built into the substation wall .
The excitation and the striker was used to create the mercury vapor in the bulb it's all history now.
Be careful with mercury keep it in a well vented area.
Thanks for the video !
"this video is a bit long" That's what we want, fella.
Still not long enough if you ask me
Didn't expect an unboxing video on this channel. How very modern of you!
It is funny on which channels i can find you in the comments section, as a subscriber of yours. The ven diagram of overlapping channels is borderline creepy :D
Yes every channel I watch is getting ruined with an unboxing series < sarcasm
Is hot tub stream next?
Only unboxing video I've ever cared about. That is some engineered packaging!
A wild Jeff Geerling appears!
Happy Days, I'm old enough (82) to have worked on mercury arc rectifiers. Steel works where we had 500 volt DC and 250 volt systems. Can't remember the rating of the rectifiers, Big yokes in metal cabinets. This brings back som happy memories, thank you ☘️🇮🇪☘️
The glasswork on these is truly magnificent. All vacuum tubes are gorgeous in my eyes. But, mercury arc rectifiers are just down right sexy. Thank you for sharing this amazing experience with us.
It’s reassuring to see that I’m not the only one who gets all excited about such things.
"Use the skippy button"
Nah bro. Im in this for the whole video.
Snow flakes can’t pop it! Photoinduction can!
This really takes me back. In 1995 I was doing a job at the old Simpson's building in downtown Toronto and one of the maintenance guys was leading me to the area where I was to drop my delivery. We passed this area that was significantly hotter than the others and there was this dreadful humming/buzzing sound. I asked what was up and he smiled, passed me a long lab coat and dark goggles and took me to a bank of cabinets. They looked like industrial lockers only much larger. He opened one up and there was a massive mercury rectifier running and he explained it was powering a good portion of the building. This thing was huge and he told me that it contained around 50lbs of mercury. I knew these things were really old tech and I was shocked to see one still in active use. then I looked to the side and saw the bank of similar cabinets and realised this one was not alone.
There are several of them still in service in the downtown Toronto area, some in the TTC streetcar power stations, and in several old elevator control and power systems. I am friends with an elevator tech, who was showing pictures he had taken, on a service call.
They are in most 1940's and Cold War Bunkers all around the UK, which are also still there. Some still work.
Check TheSecretVault, many of his urbex videos featuring massive nuclear bunkers will reveal everything else that they were attached to.
We are not alone!
Epic last line.
Thanks for this. I have memories from when i was an apprentice electrician at the BR Carriage Works in York, 60's to 70's. At one point i was assigned to the maintainance department for the works, which was also attached to the main transformer station for the works You can imagine a huge amount of power needed. The works had two traversers which would traverse the carriages from out of one shop into another. At the time these were still powered by 400Volts DC. In the transformer station was a large metal containerprobably about 6 foot x 6 foot x 8 foot high. Painted dark blue with a sign saying 'THE TARDIS'. Emanating from above was blue/ ultaviot flashing light and a strange science fiction film sound. When the door was opened it was a sight to behold. 6 of the above mercury rectifiers. No doubt we should have been wearing dark glasses and sun cream . At the time i had no idea of how they worked, so cheers for this.
my stepdad did a bit there before becoming a guard, i think the times may have overlapped slightly with yours, so you may even have met him, brian cox was his name.
im an electrician and i love that kind of stuff. must have been an amazing thing to see up and running.
It’s also really funny how they possibly reused an old police box as an enclosure for a mercury arc rectifier! :)
That extra special touch -> "Please handle with EVERY care!" That makes me smile.
No one skips your videos, sir.
We do appreciate your humility though.
I do.
I skipped. Seen the good stuff.. and then went back and watched the whole thing...

This man is the grid
Ah! Takes me back to the start of my career in broadcast transmitters. The more modern transmitters then (250kW carrier power) used Excitron mercury arc rectifiers. They had 2 banks of 6 Excitrons, with the transformer windings arranged to give 12 phase rectification. Output was 11kV DC - the radio part of the transmitter took about 26 amps, and the high level Class B modulator another 15 amps depending on audio level (approx - from my memory). The rectifiers were in a cabinet with glass windows so you could see that lovely blue glow as the arcs were struck - then the light output would vary with the audio modulation. Quite spectacular when the Greenwish Time Signals 6 pips came on (they modulated the transmitters to 100%) - the extra current draw caused lights to dip in the nearby town in step with the time signal! Oh, and the older transmitters (built during the 1940s) used mercury arc rectifiers in massive steel tanks with continuous pumping to produce the required vacuum. They used grid control to vary the output as required. Incredible to think about now!
Ho i brividi di eccitazione leggendo questo commento, vorrei essere li
And now a MUCH smaller (in comparison) diode quietly does the exact same thing...
This is why history is so interesting. This was the norm at one point and that's fascinating to me.
You can tell he's grown up boys. He's protecting the carpet with plastic
It's the new wife probably lol.
Was thinking the same thing.. the wife is asking him "please don't burn the fkn carpet and try keep it clean" 🙄
Burning a carpet is ok for later use. Spilling mercury ... isn't.
Only from the mercury, burn mark in the carpet = meh, mercury all over the floor = oh fucking shit
Mercury on the floor = Biohazard cleanup crew, stripped up carpet and underlay, chemical cleaning in the worst case scenario and an expensive hotel bill while the house is sectioned off. If not mercury poisoning literally kills neurons via breaking down of the structural tubules supporting the axions.
The engineering involved with old things like is amazing. But can we just take a moment to think about the master glass blower that had to make that assembly, and the people who installed the metal parts to it. They mass produced these.
They would have made exceptional bongs
@@JG-nx3jg you bet your sweet bippy they did
Yeah, back in the day glass blowing was a career, and always in demand.
@@tncorgi92 it still very much is.
I couldn't stop thinking about that the entire time.
You could open your house as a museum for electricians. Well, i'm no electrician (yet) but I love hearing the history of it all.
Having worked in a 50 year old power station and been through various store rooms, I know exactly what that thing would smell like when you unboxed it
That was one of the most "belongs in a mad-scientist's lab" looking devices I've ever seen. Thanks for the educational bits - really interesting to see this old tech in action and to learn how it works.

You can literally watch the video as many times as you want. 😊

The small bubbles that appear on the interior glass surface of a mercury arc rectifier after some time are typically due to a phenomenon known as mercury vaporization or mercury spitting. This can occur due to the high temperatures and pressures present inside the device during operation.
When the mercury arc rectifier is in use, the mercury in the arc is heated significantly, causing some amount of mercury to vaporize and become gaseous. These mercury vapors can then condense on cooler surfaces such as the glass interior of the device, forming small bubbles.
This phenomenon can be more pronounced if there are leaks in the device or if it is operated under abnormal conditions, resulting in increased mercury consumption and the formation of more bubbles.
It is important to note that mercury vapors are toxic and should be avoided from being inhaled. If significant condensation of mercury vapors or an increased formation of bubbles is observed, it may indicate issues with the device's integrity or operating conditions. In such cases, it is recommended to cease the use of the mercury arc rectifier
The transformer noise is labeled as "music" in the generated subtitles. It is indeed.
yeah lovely buzz! could sample it and use as a nice bass or lead.
A flat (if anyone is interested) ;o)
It's beautiful!
50 Hz sounds so great, soothing and menacing at the same time 😈

That is the coolest thing I've ever seen, not even joking. I had no idea these even existed until now. Thank you for this! You are a legend.
These were used in the early experimental British Rail 25kV AC electric locos. The production locos that became class 86 used Si rectifiers. Have never seen one run so this is quite fascinating.

I am seriously impressed. A few questions. 1) Would you please publish the listed specs for this device? 2) What is the best feature of a mercury arc rectifier? (cleaner output, lower temperature, high capacity, easily handles current surges) 3) It would be nice if you published your results, AC input, AC current, DC output, DC current, Output waveform, etc. Hope to see another video like this.
High capacity, and overload is about it, when compared to current day silicon diodes.
We have a saying for children that translates to "Everything for the eyes, nothing for the hands" regarding museums and exhibitions.
I think this room is the manifestation of that sentiment.
That’s the general idea at substations as well, one hand in the pocket if you know what you’re doing, both if you don’t and are just looking.
I remember asking for a demo of this about 5 years ago. Now my dream has come true. :-)
Early tech is both fascinating and scary! Can't even imagine the wild ways they managed to do things with what they had back then vs now.
Yes, equipment size in electrical engineering has gradually decreased whether it's in power devices or computers or else, all thanks to pioneering advancement in solid state semiconductors.

A collaboration between Photoninduction and the Slow Mo Guys would be amazing! I'm thinking of all the amazing footage from both their combined knowledge in their respective fields.
When I joined London Transport in 1979, as a substation tech, many of the original substations still had these working.. Very eerie, but comforting on a nightshift. Sadly most had been converted over to SCR by 1981.
I have so much respect for this mans knowledge. Electricity terrifies me.

I love these old mercury rectifiers! They look so utterly "mad-scientist". And this is probably the best footage of one running that I've ever seen. We're all so lucky PhotonicInduction is uploading again. He is absolutely legendary!!!
came here to say this, but you put it better
@Mark O So true. Love the explanation of the different types also. As Photonic says, they are mostly built inside cabinets and poorly visible on other video’s.
“Are you bored with it yet ?” .... Never !
You might just be mad but in the best way possible.
I did not realize the solenoid was only needed to start the rectifier and all you needed was to get the ( dippy thingy ) bouncing with a hand held magnet.
Very enjoyable!

That is a bloody gorgeous collection of mercury arc rectifiers you have there. Museums hide such things away but here they're being shown in their glory. Just beautiful.
The Kempton Steam Museum has a couple 6 phase Mercury rectifiers on display that are used to power some of the building itself.
Really interesting. Brought back some good memories. We had one of those as a battery charger and it was still in use in the 90s when I left London Transport.
This dudes bong collection is off the chain!!
Great comeback 🤣
LOL !!!!
It's art dude.....now drop some wax on that nail.
This would be the perfect decoration at a Halloween party for a mad scientist.
Speaking of halloween... If i saw that as a kid i'd be intrigued if i knew it was a piece of vacuum tube electric gear beforehand, i liked the purple glow in big rectifiers, but it would still freak me out.
If i saw it in the corner of a basement without knowing i would be mortified, bad dreams for years!

The Isle of Man Electric railway used these until only a few years ago. I remember seeing them when I was last there! You could see when the motor on the train was pulling some amps as it would light up really bright!
Bit of trivia, if you have ever seen a fluorescent lamp which is dark at one end, it has a damaged electrode on one side and it is rectifying just like this and the DC is causing all the mercury to migrate to one end of the lamp hence why it's gone dark!
Heh - I just posted video of that one: th-cam.com/video/yjMZ5qtyCUc/w-d-xo.html
They are something to see in person!
I’ve also seen one that flashed very rapidly, regularly and intensely. I think it was on an old 60hz magnetic ballast. I imagine rectification was making it light every other half cycle, creating 60 short duration flashes per second.
@@deltab9768 If you are talking about the tube on start up it will be cause of a preheat ballast
@@crazy-es8tr It was very regular, you could see a "smeared" strobe image on moving objects with a bit under 50% duty cycle. It was very fast (at least several tens of flashes per second.) It didn't stop after the tube warmed up, and it was slightly dimmer than a good tube. I still believe it was rectifying, but not 100% sure.
Certainly is a piece of art, the craftsmanship that went into the glass blowing for that is amazing, they're such impressive pieces of technology from the past... :)
Hell yeah, fantastic timing on your upload as I was just learning about these (relatively) ancient beasts for the first time just a few days back. After grasping the basics of their operation, I naturally wanted to see one of them in the hands of a professional lunatic, so this is all very much a sublime confluence all-around as I see it...
I am very happy that you are putting more explanation into how electrical devices work and why. Cheers.
This is probably Electroboom's favourite video.
