Did you use a sky filter on the camera? You got one hell of a beautiful blue sky background.

dont let that arc touch another line it will blow up!

@ApolloWasReal i know that mate, you're talking about reactance, vectors etc. i had trouble understanding your terminology at first so i assume you're in the US. i'm aware of the difference between watts and kva and the application of power factor correction and such like. the term "reactive line" led me to believe you were referring to a single phase/line whatever you want to call it (IET can't make their mind up about terminology, changes with every new set of regs!!!)

@dunkdriver1972 It's more complicated than that. In an AC system the power is rarely equal to volts times amps, because the current waveform is rarely in phase with the voltage. Even without a load on a line, current will flow because of capacitive effects but it will be 90 deg ahead of the voltage so it represents no actual power flow. That's why an arc appeared here even though there was no load on the line.

@ApolloWasReal there are three lines on a three phase system offset by 120 degrees. the current (in amperes) will vary depending on the overall load. the only time the voltage changes is due to volt drop over the vast distance, hence the reason for stepping up the voltage. V=IxR. hope this helps.

@azyo99 omg! that's the best kid story i've ever heard!

@marc002925 Rerouting power to or from another source. Probably doing work in the area. I seen a guy flip an air brake once, that was cool as hell. Kinda like in the video. Then I went and looked at it and they padlocked it so you couldnt mess with it. Bummer. LOL

This electrical buzz sounds, like a Cybermans voice in Dr Who and it penetrates through a person.

Recording with your fridge is always a good solution. Perfect quality!

@bradjay1215 So you're just interrupting the reactive line charging current. How many amps for a line that long?

Most of you are correct about opening this up under load, it simply wouldnt open without a melt down. I was de-energizing 30 or so miles of 69kv that we re-routed. We looped the curcuit. Then broke parallel at a substation on the end of this section in the video. So the reason for the video? Watch the far side stick when we opened. This was a known problem at this location and I expected a far worse outcome.. So thanks for the comments and work safe.!!
