You put an egg in my beer and I'll punch you right in the mouth..... :LOL: :giggle:
I never liked tomato juice in it either but a lot of my friends did.

Second that! You know you on shi* beer when you need to add something to choke it down. Guinness Extra Stout is right for me.... Or a good Trippel

Sorry man, I deal with pump guys all the time that don't understand these. That cap is NOT causing voltage rise, it's because the motor is running, causing back EMF, which is switching out the potential relay, as designed. I actually teach this stuff......to pump personnel. If that cap stays in circuit for more than about 2 seconds, it will explode.

Facepalm, I should have just owned it and went all Aussie on ya.....:ROFLMAO: Krykees.

There are better vids somewhere because this is also common in HVAC, which is what he presented. I remember watching some students in a classroom when this came up. Talk about deer in the headlights. I have to remember that many HVAC techs have only that tech school education in electrical so it's probably a lot to digest.

I also work in engine performance and always asked how to learn more about making power. I tell them to buy and absorb aerodynamics and fluid dynamics books. I always get crickets. People don't want to learn at depth, just tell them what they need for today.

??? That is not even a thing!

How is it not. I have seen 3phase pumps operated on a single phase supply with a cap bank set up to “add” if that’s the word you want to use an additional phase shift.

I wouldn’t recommend it nor think it’s the best way around to do it.

No, sorry, I already know when someone says something like that, no math was ever computed, no scopes were used, just a WAG. Yes, you can single phase a 3P motor, no problem, but you certainly will not get full power. With factoring, you are at 50%.

No OEM or designer would do such a thing because it's like designing up a nice 8 cylinder engine, then purposely unplugging half the spark plugs.

I stand firm that static converters are something that should be UNinvented.
