We just had a line of storms blow through Northern Virginia with many
hard power hits but power never went all the way down. On the power
pole in front of the house there are cylinders about 3" in diameter
and 3" long hanging from each of the 3 high voltage lines about 1'
from the insulators. Each cylinder has a blinking red led on it.
Two questions, what does it mean when the LEDs are blinking and how
do you power an led on a box hanging on a 13KV line that looks like
it could handle several hundred Amps.
