In my mind it's good to let load 'settle' overnight if it hasn't been moved in decades. The last thing I would want is someone to immediately begin working underneath it only to later find out that it was 30 minutes away from catastrophic failure. I wouldn't know what kinds of hidden stress fractures after decades of operation there might be.

I thought it was really interesting, on that chart, to see how additional threads add additional strength. Really cool! Of course, i really love this kind of practical nerdy stuff

Thank you for these videos. I'm fascinated. What's the output capacity of the generator?

@Physicsduck 2 жыл бұрын

Nominally she'll do about 400kW or so, but right now the water's so low we're lucky to get half that.

That is a hell of a point load under those bolts. With steal and concrete taking most of it. Ouch, that is a heck of a pinch point.

@SeanBZA 2 жыл бұрын

Not worried about the bolts, more the century old threads in the alternator base that they are in, as to the failure point. Those likely are the original moderately loose tolerance threads from manufacture, which are a lot more likely to shear before the bolt fails.

How many lifting bolts are there and what is the engagement depth of the hold down bolts, also thanks for taking us along, I really enjoy load transfer and rigging, generators are about as cool as things get

Fascinating. Big boy toys! 👍😎👍

@lawrencejob 2 жыл бұрын

Isn’t it conservative to use clamp force for a jack bolt considering it’s a compressive load? Or is the limiting factor the sheer strength of the threads?

I workered in the water treatment plants in South Florida. Lot of big heavy work. Where are you guys and where do yo work. I find your videos very interesting. And did alot of the same kind of work. I currently work at the city of boca Raton. In south Florida. Typically pump 60 M G D

I'm in the wilds of Michigan, working for a fleet of small-scale hydropower plants. I don't know how much water we move in a day.....let's see.....we're at about 400 Cubic feet of water per second today, so that's....what, about 250 MGD give or take?

What happens in the event of an unforeseen grid disconnect? Is there some safety equipment that prevents the generator overspending and shuts it down?

@kls2020 23 күн бұрын

Once a generator in electrically synched to the system it is paralleled to it is magnetically coupled and basically locked in . The only way you could have what you are describing known as a "slipping pole" condition would be if field strength to the generator field windings were to be somehow reduced to a level that allowed the force of the water on the turbine to overpower this reduced magnetic coupling between the rotor and stator windings such as because of a field current failure . Many Hydro generators have a special winding built into the individual field poles known as an "Amortissuer" SP. winding . If a slipping pole condition starts to occur currents are induced from the stator into these special windings increasing the magnetic strength to prevent pole slipping . Due to the rotating mass involved the vibration created by slipping poles is unbelievable and can be highly destructive to the generator . Most generators with have other protective devices installed as well to immediately trip the generator offline should this type of event occur .

I've always wondered something about hydroelectric power, but whenever i ask i end up drawing an awful lot of suspicious gazes and few replies.. Do all of the systems have redundancies, or are there any single points of failure that cannot be helped? (I had an electrical engineering friend tell me, years ago, that when it comes to powering the grid, "There will always be SPOFs, the best you can do is improve ways to mitigate damage". So, seeing you make these videos about this hydro plant, i've had his statement rattling around in my head XD
