I wonder how many volts were on that cable? I think the standard voltages for distribution is now 69,000v and 115,000v in most places. Some lower ones are 13,500 volts but would not draw an arc like that. The house we had in Duxbury was fed underground from the road to a transformer closer to the house. It was 13,500v in a coaxial cable to the primary of the transformer. The secondary fed two, 200 amp panels in the house and another 100 amp panel in the garage. It shorted one day where it ran into the ground by the road and the whole ground shook. It's amazing though. The primary fuse on the pole is only a 15 amp fuse. Lotsa volts anyway. It would not open for me. Around here, street distribution "medium voltage" is 13.5kv wye. "Transmission" is 230kv delta. |

A lineman in a bucket lift uses a cutter on a long insulated pole to sever a high voltage cable. As soon as it's cut, the cable throws an arc about 3 feet long into the air, lasting less than 2 seconds. It's amazing what a bunch of ****ed off electrons can do. --- This email has been checked for viruses by AVG. http://www.avg.com |

Lotsa volts anyway. === Lotsa volts for sure. I sort of recall a rule of thumb that electricity can jump a 1/4 inch air gap for every 1,000 volts. I'd estimate the arc in the video at about 3 feet, which leads to a quick voltage estimate of 36 x 4 = 144KV. It might have been lower however because once an arc is struck it can extend farther because an ionization path already exists. That's the principle behind a "Jacobs Ladder" which is kind of a cool demonstration. https://www.youtube.com/watch?v=6hhaaSSCU5k --- This email has been checked for viruses by AVG. http://www.avg.com |
