I'm an up and coming electrican and if i didn't know any better that looked like a serious arc flash which i read and heard about a few times already since beginning classes
You might want to do some research in regards to trade schools in your locality that offers an electrical technician course i just started school about 4 months ago and should be finishing up the ending of June it's alot of information involved and i hope you like math lol if you're serious about it i think you would do well and i recommend it for young people who may just be wasting their time with their lives doing nothing best thing for young people to do is learn a trade
Just for record, you can tell high voltage, 200kv or more from high current by size of wires. Often there will be three sets of three, the wires in each bundle are wired in parallel to reduce resistance.
A high tension line will use realtively small guage wire.
Not sure where you are, but here in the US you can find > 500kv lines with 3 phases, each phase consisting of 4 of the largest diameter cables available bonded together into a single conductor. That's because the line handles high voltage (high tension) and high current both. Typically the limit for the line is the amount of sag in the cables due to heat from the high current flows.
About frequencies, I understand that Tesla determined 60Hz to be the most efficient for generating and using power. 50Hz was chosen in Europe because they were so fanatical about making everything come out nice in the metric system... so they exchanged efficiency for nice numbers. 40hz is not used on any normal power system in the world. 60hz, 110-127V power is used throughout the Western Hemisphere, 50hz 220-240V in most of the rest of the world. 240V, 60Hz is ideal, but rare.
planes actually use 400 hz with their power systems. And in the US, a typical residential service uses a "split phase" system with two 120VAC lines each 180 degrees out of phase with each other. One hot to neutral = 120 VAC, hot to hot = 240 VAC. Commercial and industrial services use three phase connections, at 120/208VAC or even higher in some cases.
What causes the humming sound is the phases of electric crossing in a shorted circuit. The humming usually stops when the wires melt and the phases separate with a bang.
There's also fault-current, which is many times the actual current typically found. A simple 16A outlet (uk) or 20amp outlet(usa) can pull a peak of 20,000 amps before the breaker pops. If a 460 UK) or 240(USA) circuit, double that if both lines are affected.
Remember its not the safe capacity of the ciruit (ie, current carrying rating of the GPO, cabling or breaker) but what current ends up flowing through you that determines what kills you or not. Depending on what you read, anywhere between 10mA and 100mA flowing through the right parts of your body (eg heart) will kill you. This will all depend on where your standing, what points of your body touch the conductors, etc. This is irrespective of the line voltage, phase, frequency, capacity, etc.
maybe the higher amperage that we have in the US and Canada then is the reason that high-voltage electric is so loud and explosive like you see above. LOL
Interesting 98770! And by the way Massive, in the UK and other parts of the world where it's not 60Hz, it's 50Hz; there's no place in the world I'm aware of where it's 40Hz. Generators would have to be REALLY screwed up to create that frequency.
I'm a Electrician from the UK, Electricity is produced at 50hz, our domestic supply is 240v ac a socket is rated at 13amps, a socket circuit is rated at 32a for a ring, 16a for a radial. A lighting circuit is rated at 6a (in most cases). The US is 110, but I heard the amps are alot higher, and at the end of the day its the amps that kill you not volts, human skin can insulate upto 60v ac. 4v - 200a down your piano finger and your doing the electro moonwalk!
USA, most outlet circuits are 20 amps, lighting 15amps, dryers&HW heaters are 30amps and electric ranges are 50 amps. Typical house service is 200 amps rated.
that was an awesome show. I'm a big enthustist my slef of high voltage, tensions lines, and lines man in study. Great video of what happens when cut-out switchs fail to do there job. Makes me lery of what I'm in for!
Yeah the noise from those high-voltage, high-amperage arcs are really loud, due to the "vibration" of the 60 Hz, for lack a better term. It's some type of physics thing that says the higher the voltage, the louder the vibration noise.
approx 1km away .... must be really loud cause the camera can hear it very well

some ships used over 100 hz? maybe 200 hz?

Perhaps, I'm not familiar with shipboard power systems!

No. Shipborne electrical systems are always 50/60Hz.

It's true, the UK and many other European countries run at 50Hz AC. The USA runs at 60Hz 117VAC.
