Bad weather auto disconnect

Don't wait until lightning strikes
  [vote for,

Everybody tells you to disconnect electronic devices during a thunderstorm, but what to do if you are not at home? When I saw the disconnect system in the link the mental lightning flashed. Put a combined water and optical sensor on your roof. When the sensor gets wet and detects flashes all plugs on electronic equipment pop out of the wall.

Output from a PC based lightning detector [oneoffdave, Oct 04 2004, last modified Oct 21 2004]


       Well, I'm sure our fellow bakers will find something to comment on, but there's sometimes I'd want this.   

       The only strike-storm I've ever suffered from took out the electric fence box and my phone answering machine - everything else was OK. There was a burn mark on the side of the house....The horses were completely bored by the whole thing, go figure....

       + for the idea. But would there be a way to somehow wire this sensoring device to the main circuit breaker for the house? Would this make a difference? If the circuit breaker is off and appliences still pluged in, could lightning short them out?

       [vOrtexx] You could wire in a main breaker with a huge contact gap but a lot of lightning damage these days does not come through the mains. Those are nicely protected. If you live in the US in a rural area you probably have a transformer can at your house. It offers near 100% isolation against lightning strike on the incoming high voltage line.   

       It is the ornamental plastic lamp on your driveway that catches just a fraction of the lightning and routs it straight into your house.   

       Those are the rational arguments. The emotional argument is that I would just love to see those plugs fly.

       The best sensor to use would be a lightning detector and set it ot disconnect when the storm comes within a cretain radius of your home. Most pc based ones tell the differenc between cloud-cloud and cloud-ground strikes. An example can be found at the link.

       can you not get it to check weather.com for bad weather where you are ?

       What about using a relay or something to cut the power?

       So, it doesn't turn the car off in bad weather...
