Excellent video! I'm working on an energized work policy for my employer and this is very helpful.

Fantastic I-R shots!! It amazes me to see an A/C flex cable "stand on end" like a hydraulic or air hose will!!

Interesting video, it's nice to see the slow motion footage and infrared footage. Thanks for the detailed explanations!

Great video! Can I use a part of this video - the explosion at 1:30 and another at 3:29? Gonna use in my own report on electrical dangers facing line workers. Thanks.

wow ! so the original bang ionises the air...creates 'plasma'....good conductor, ( like metal apparently !) .........so it sort of feeds itself once it gets going...untill if / when a big enough current is raised to trip whatever protective device is upstream....brutal ! A real monster. and If the current raised is not high enough all the burnt out junk remains live...scary

Probably large capacitor banks to allow for the high peak currents.
@weeardguy7 жыл бұрын
Probably not. Cap-banks will trigger DC-currents, which have no use in AC-current systems. (Arcs behave far different on AC than on DC) KEMA's test facility in the Netherlands has a very large rotational-converter with a huge flywheel that is first brought up to speed. Right before the short on the equipment under test is made, the motor that drives the converter is disconnected from the mains and the energy left in the system powers the short (You can hear this in some videos, as the frequency immediately drops due to high currents that slow the flywheel down dramatically) If I remember it right, they were (or are) building an even bigger test rig that has an artificial 'grid' so they can test with higher powers and voltages without interfering with the main-grid.

nothing like molten conductive particles in the air continuing an arc flash and moving with every slight air current, induced by the heat from arc flash or the winds. probably better with low to medium winds and working upstream at an angle, so it all blows downstream away at an angle.

"Tom Short??" What a name for a speaker on an ARC flash video. . . Watts up with that anyway? I guess there wasn't too much "Resistance" from management on this one. And of course, it was a "Transformational video!"

At least he showed potential. seems like he has a good grounding.

5:45 arc blast outside. 6:15 arc blast outside from behind a blast wall.

Odd. Why say "two double oh nine" instead of "two thousand nine"?
