Nah, I hired an electrician to handle all that for me. Now if I want electricity all I have to do is stick a plug in a socket, or flip a switch. It’s way more convenient.
My understanding is that if electrical demand starts outstripping supply the sinewave can start getting badly mishapen.
From watching videos about synthesizers and playing with VCV Rack I’ve learned far more about waveforms than I ever did from any electrical education or research
Not exactly. There’s a ratio of RPMs of the drive motor to the specific input of the alternator that generates the correct frequency. It depends on the way the alternator is designed (ie number of poles) that will yield the correct frequency, almost like a gear ratio, that is optimized for efficiency, and power plants have to constantly make slight adjustments to the drive motor speed the keep the frequency exact (usually done automatically within the drive control system).
I’ve never seen frequency be an issue in a residential system, but in theory it could happen.
I don’t know how it’s in 60Hz regions, but here the generators are in 3 phases, 120 degrees apart. The voltage gets transformed to up to 400kV, still in 3 phases, and then down to 400V when it’s distributed to peoples’ homes. Then you can pull 400V 3-phase or 230V 1-phase from your wall.
It’s the same here, though we have varying degrees of transmission and distribution voltages via transformers and regulators. In my area, power comes into our valley from the 500kv lines through the open desert, into the valley at 33kv, and stepped down to 5kv for neighborhood distribution that the single phase 240/120v transformers tap off for the EOL.
More of what I was getting at was that generation is more or less the same across regions. Some external fuel source (whether it’s diesel, natural gas, nuclear, steam, etc) does its thing to drive a rotor that’s connected into an alternator which is essentially an electric motor but instead of the electric motor doing the driving, it’s being driven which generates power, and the RPMs of whatever given fueled drive mechanism are not necessarily 1:1 with the alternator speed.
It used to be common for clocks to be driven directly off the electrical frequency. The US Navel Observatory would call up generator plants and tell them to slow down or speed up a little to make a correction to all the clocks. I’m not sure if that still happens, though.
I’ve heard that trope before, same reason clocks in US schools/govt institutions were always plugged into a wall, hence these. Nowadays, NTP has rendered that obsolete.
Yeah, I agree. They messed up the scheme we had going. It was a good thing, and electrical engineers had to come and be all different, confusing everyone else along the way.
From my point of view the mathematicians are evil. I can’t stand them using i in my math classes, messing my whole scheme up. Respect for my physics prof in my first semester for switching to use the correct letter j
There is hope for you after the asylum. My daughter has an EE degree. While in school, she would call me every October and tell me how terrible it was and that she wanted to drop out. I would talk her off the ledge, and she got through.
Now she’s working, making more money than I do in her early twenties, and she loves loves loves her job.
Luckily I have 6 years of Electronics manufacturing experience, so the math and theory are the things I’ll need to learn most of. Unfortunately, those things are the hardest part…
Town where I grew up had an awesome laser tag - you started off with a basic blaster but could unlock a shotgun (more damage, but fired slower and had limited ammo) and a rocket launcher (single shot insta kill) by doing different things in game
I only experienced laser tag once. Where I’m from the kids can go skating and rent the same old moldy leather skates from the 70s with metal bits tearing into their feet OR they can smoke meth with Skooter, Pooter, and Mooch down by the creek.
The last update the skating rink seen was when Britney Spears sold Pepsi. Even then they only updated the posters.
I will always point out with this meme that there is no need to say “with ribosomes attached to it” if you refer to the rough endoplasmatic reticulum. If it does not have ribosomes it is the smooth endoplasmatic reticulum.
