Electricity is scary and amazing. I'm always wowed when I see videos of arc flashes like this, because at the second the arc goes off, the entire screen is bright white, like you see when a nuclear bomb goes off! It's scary the amount of energy released! Gives you a healthy respect of it (or fear as the case may be). LOL
@lakewood85 - Good ? ... Europe uses 50 Hz because it better fits the metric system. And after WWII the voltage was doubled from 110V to 220V because higher voltages use less copper, which was expensive at the time. The proliferation of 110V in North America prevented the doubling of voltage but large appliances still use 220-240V plugs.
I was thinking it is hard to protect yourself against a incredibly powerful 2000~3000 Mega-Watt flash-over blowing up in your face. I can imagine the massive white hot explosion, sending the 80Kg test dummy into the air, along with part of the conductors, insulator and clouds of vaporised metals and sparks. It as powerful as several sticks of dynamite, the physical force of the blast can crush you. It way more powerful than the arcs and explosions posted on u-tube so far. A system disturbance!
This is one of those moments where you get to say "I wish I worked there!" Nice video, Looks like a lot of good research can be done there, Especially with that large MarX generator I saw behind a sheet!
Several utilities are involved in this ongoing study to make arc flash calculations realistic for higher voltages. Arc Rated clothing usually prevents deaths from arc flashes and dramatically reduces injuries over ignitable clothing but we need to help protect better. Lots of work to do on this front but moving to arc rated clothing is always good.
Too much talk. Not enough spark.

Why do we use 60 hz electricity and Europe uses 50 hz electricity?

@Photonicinduction
It seems the flashover was conducted with AC; probably no capacitors involved.
2000 MW yeah! xD Only like, 750 kV and higher voltage lines are capable of that.
