Automatic generator start

andrequeiroz.com

My electricity grid is dropping frequently. When the power drops, I have to manually connect a small diesel generator.

I would like to use a raspberry to automate the triggering of the generator.

Which sensor should I use to detect the power drop ?

 

ops: 380v

  • It would seem that you need a battery or uninterruptible power supply to run the Raspberry Pi when the power fails.

    A simpler method would be to have a relay that is powered by mains voltage. When the mains power fails the (normally open) relay switches on and triggers the generator start sequence.

    Mr. Douglas your idea is very good and practical, but the generator can not be triggered immediately. I would also like to register some data by raspberry for reporting. I think the best alternative would be to monitor the electrical grid with sensors.

    Is there any digital sensor that identifies phase failure?
