stumbled on one mercury rectifier at the kempton steam museum channel and 42 videos later i’m not disappointed

Kind of reminds me of the old toggle light switches at my relatives places. Grandparents both sides don't know if for sure somewhere made around the same time. But it's very likely that there are about the same age very possible. I do know on my father's side of the family the house is built in the fifties! The other is a farmhouse on my mother's side of the family. Even though they're very reliable on the place on my father's side were swapping them out for modern switches even though they're still working just so that it's a bit quieter when you turn on and off the lights as well as just long-term reliability possibly doing a few remote switches where there's no possibility of putting in three-way or four-way switching. Or where is just an awkward spot for the light that it controls! Ungrounded system unfortunately if there is what appears to be grounded it's boot leg grounded! Have a feeling that both places were made around the same time. For one thing the old the Double T slot receptacles are in both here and there but not consistently around the whole place. One place my parents stayed out with built in the 40s as well come to find out the safety switch for the furnace had a fused neutral didn't get a chance to fix that before they moved out! That place is basically a basket case in terms of things that would have needed to be done to bring things up to even minimum standards unfortunately. Speaking of satisfying switch action. I remember at the old church there was one set of lights that was controlled from the voltage switching it was also the lights that were on the Auto Transformer remote control dimmer. It's not the switch itself that was satisfying but the clunk of the contactor coming on if you weren't used to it if you're in the vicinity you jump a little bit! Probably one of the loudest contactors I've ever heard in my life. Also on my grandparents place on the farm one switch the one that controlled the stairway lights up to second floor- and the Attic. Window switches you turn it on and there be a slight delay before the contacts were closed I've never seen a switch do that before I think it's just was a bit wonky for some reason no clue why that would happen and that's of course it was dunked up or something but it wouldn't be consistent if that was the case. And no this is not some special type of switch or something it's just happens to do it and surely not intended to have this happen. Somewhere I've got an old toggle switch that I believe right at 60 amps AC might be more than one pole as well salvaged it off a big old power supply that was being scrapped out since it was beyond repair unfortunately! Transformer had failed well my buddies wanted to see if I could use anything on it or wanted to save anything that he wasn't going to use and also help him strip it down it was a real Beast originally it was for either a carbon art projector or possibly a a photo spot we're not sure which but we do know that it was used in the industry! Huge selenium rectifiers in that puppy! Matter of fact I believe there's still a video on here with something very similar possibly even the same model but it was so long ago don't know for sure. Have run across some really big Mercury rectifier tubes and as well as tungsten are going rectifiers as well here and there sometimes still working condition and even being in service. Had used a couple battery chargers that use these as well to charge a few batteries here and there. I built a old school battery charger years ago but you had to be very careful since it was not isolated from the AC line told everyone unplug the battery charger before even touching the vehicle and just in case. Specifically said unplug just in case issues with the switch. Essentially consisted of a light bulb and a chunky Bridge rectifier that's about it it was literally built into a junction box and the switch was mounted in a knockout also used old school ceramic bushings for cable entry salvaged those from old power supplies from fan steel which were originally used pipe organ power supplies also had used some of those power supplies that fixed up as well

the loud, solid clunk of the switch, followed by the strong, buzz of that pretty huge transformer, then followed by the slowly orange glowing of the heater, followed by the nice light blue glow...😮❤

We use mercury contactors (3 phase 480/240 vac, 120 vac or 24 vdc coils) in our machinery at work. Used for heater bands and a PID temp controller.

How do you adjust the current/power to the carbon electrodes? I have similar rectron rectifier rectron 90V 25A. I have 12mm positive carbon and 8mm neg.on my AGA Baltic ultra 2 .I belive the voltage should be around 60volts . How much the voltage(90) alter under load ?

Why does the carbon arc need to be run on DC? The rectifiers are really cool, and I love old electrical stuff, but why rectify the AC? Would it not run on AC?

The 60hz of the arc would interfere with the 48hz shutter of the projector and cause a slow beating flicker of the image on the screen.
