The oscilloscope has to be my favorite tool ever created. It makes everything mundane into something incredibly interesting. I was a radio tech in the USAF, knowing what your transmitter is doing on paper is one thing, but being able to actually _see_ the data on the carrier wave is so much cooler.

What I want to see now, is the set up you rigged just to capture this, so maybe I can fathom the marvel, or maybe try recreating it?

@otteszchannel2012 Ай бұрын

is it a transformer problem?

@kevinjbakertribe Ай бұрын

I am guessing (as i think others have said) this is an arc fault (e.g. tree shorting overhead lines). It tries reclosing once fairly quickly, but the fault returns, then a bit later and the fault has cleared. Using an amp to recreate is genius!

One thing I still don't know is how they keep 60Hz - precise enough for ordinary clocks to keep good time. Obviously all power plants need to be synchronized - and, in fact, a given power plant cannot be out of sync with the power grid. That is, a generator connected to the grid cannot spin too fast or too slow - otherwise very bad things happen. Yes, that's understood (basic electromagnetics - physics). The question is a bit like asking which came first? The chicken or the egg? What entity (or collective?) maintains 60Hz (or 50Hz in Europe). How is that achieved exactly?

@laurensvisser7623 23 күн бұрын

Usually some master clock such as a cesium clock. In a year (month, day) the number of cycles needs to be a certain number to reach an overall average of 50 or 60 per second. If the number of cycles is too low, power plants are told to increase power and RPM slightly to make up for the lost cycles. At any instant, the frequency can be a couple tenths of a hertz lower or higher, but in general it's within 0,1Hz. A while ago some south-eastern european country dropped off the european grid causing a ~3GW deficit in power on the euro grid. This lead to clocks noticeably running slow, because it was that single country that was responsible for delivering a couple gigawatt to the grid, and not the responsibility of the rest of Europe. Everything was eventually turned back to normal, the country went back on the grid and presumably delivered it the power it was contract-bound to deliver, and everything was stable again.

sounds exactly like when there's an arc somewhere down the line

@Anamnesia Ай бұрын

Yeah... That’s why I’m not a fan of “modified square wave” Uninterruptible Power Supplies (UPS’s) on electronics... Those harmonic spikes can wreak havoc on sensitive electronics! You’re better off with in-line pure Sine wave UPS’s... Sure, the operating costs are higher, but your equipment is safer.

@Novous Ай бұрын

All the other comments are wrong. This is the sound a socket ghost makes, as it attempts to wiggle out of the little holes in the socket (that's why they're so small, to usually prevent them from getting out). But, if a socket ghost does enough pilates and hot yoga, it can fit through, the power goes out and the power company has to send another down the pipe to your house.

60hz? i have 50hz here. and i've been actually curious about this. nothing audible should be coming out of speakers i have. bu i can hear stuff that's not 50hz from it. it's often during weird weather. so i was wtf. i thought i must clearly hear distorted waveform but of a unknown origin. this is not regular power cut area. in fact i heard two changes right now. it's calm weather. i never tried to capture it. a power is noisy since it's shared network. it's noisy even with emc compliance. fun eh

Awesome! I always wonder what power outage waveforms look like (especially when they kill my electronics :/), but capturing them is painful. I wish I had a system to always be running and automatically capture them, maybe I can hack something together and make a firmware mod for my cheap little DSO138 lol
