Nornally first the capacitor and then the motor. The capacitor is there to absorb the power surge when the motor starts up.
If you're on single phase power, you almost always need something like a start capacitor, at least for large-ish motors. It doesn't really have anything to do with the reliability of the grid, and moreso how single-phase AC motors work.
If that is a start capacitor, OP might actually want to shut it off once the motor is running, as they're typically not meant to run continuously. Usually, there's a mechanism that disconnects the start capacitor once the motor is up to speed, but it's not strictly necessary
Pretty much all decent sized electric motors have a start up capacitor. They need an extra bit of energy to build up the magnetic fields, overcome static friction and accelerate the motor up to the operating speed.
It should be noted that big capacitors can fuck you up bad if not discharged properly. It’s not hard, but you do need to be careful.
I wonder how their opa figured this out. Did he try it out and encountered problems when starting the motor? Then maybe got suggestion to add a capacitor?
He probably had some practical knowledge when doing this...
It’s not like people in the USSR we’re all uneducated or something. Like, they knew how electricity worked, same as in the west.
Man the red scare propaganda really does live on.
Engineers are needed in all modern societies, capitalist or socialist.
Engineering education was really good. I read some Physics and some Math textbooks, and they are amazing. Same goes with Chemistry.
On the other hand, History education was all about how kings and grand dukes were bad, and how Lenin was great. Same goes with Arts, Literature and Philosophy (I once stumbled upon a book that says how class warfare was among the Greek elite, Plato was bad idealist and Democrites and Aristotle were good because they comply with the Marxist Materialism. And that was in a Math history schoolbook!) Plus a lot of discrimination, children of Party members were given good grades, even if one looks for Japan in the Africa (a real case). Ethnical discrimination (Russian chauvinism) also existed, the idea that "everything was made by Russians" and silencing the other USSR and foreign nations' achievements. We see a war in Ukraine as a continuation of this idea.
But, going back, yes, people knew knew how electricity, space travel, nuclear power and particle accelerators worked.
