    Lightning flash made camera adjust to high light level, then readjust to ambient?

    You mean lighting flash? I'm not aware of lightning - just a downed wire with plenty of juice according to the folks where I found it. Though - yes - the camera did adjust to the light.

    Can't really see the source of the flash, but it looked like wipers going so guessed lightning.  Downed wire makes sense.

    The base of the light pole has periodic flashes. When the wire is downed there is enough juice to complete the circuit to the light pole. I have no idea how much juice that is but seems a lot. Might be a good thing he wore a rubber safety suit.

    Seems to be fuel on the street though - makes no sense at all.

    Life in the city. Stay away as much as possible from cities and you will be fine ;)
     Not too many swat teams in small towns either. ;);)

    My guess, power was off to a downed line, lineman moved the cable. Then the line was on.

    I agree with BB.  Probably the line dropped down on to a live line.  Just yesterday they were trimming all my trees above/between live primary lines.  But no surprises.

    I am available for custom hardware/firmware development

    Almost seem to be flashes of light in the houses in the background too.

    People who don't understand what high voltage can do, should stay away from it. I worked with 480v a lot for may years and that was OK.
    I would not then or now, go anywhere near true high voltage based on what I've witnessed. He was properly suited up, but stuff happens,
    I always have more questions than answers. That's the nature of life.

    I'm not sure how suited up I'd have to be, to be playing with 60kv in the rain

    As far as I know in our region (PG&E, Northern California) the linemen ground the high voltage lines first (long fiberglass poles with clamps and grounding cables) before they work on the lines directly.

    I'm interested in the flames.  Perhaps the electricity turning water into hydrogen and oxygen?

    We have had 2 weeks of PGE out in the canyon replacing the 70 KV towers that power Yosemite by helicopter. Guys dangling 200 feet above 60 degree sloped granite. E ticket ride here and they work with 2 helios in close. The power is only out in 1 hour blocks which is pretty short at this level. 

    Definitely a young person's job. You have to be 100% and they often have a guy who just waits to feel better I am told. I'm surprised that helicopter can lift the full weight of these guys testicles :):smile:

    Sounds possible in a theoretical way but I've never seen water consumed by fire. Lightning bolts hit water all the time - never seen fire. 

    Makes me wonder if the whole thing is some Ingsoc psy-op in case the radical young uns plan to cut power lines if they don't get their way in future elections. 

    Perhaps the flame is burning electrical cables...  One could maybe see on a large screen with slow motion?

    The whole thing does not make sense to me.

    Plasma... From the aluminium and or copper cables, and anything on the ground (various salts make different colors).

    Helicopters around here are used to "Hot wash" power line insulators:

    I think a few years ago, there was a fatal crash of a PG&E copter while doing this (could not find an article).

    That is burning insulation and asphalt.

    Yes, I agree. As voltage increases, the world changes beyond what we perceive as normal. I wasn't there, and I have no expertise in the subject, but I will guess that the overhead line that fell, was so called "medium voltage" at 14.4KV . It is unlikely that the worker would have tried to clear a line above that.

    Isn't it one insulation disc for each 15 Kv - as I recall? Just watched a show that breached that subject : discs subject starts ~5:55 -
