I try to come back with Arduino programming.
I have a 3 phase motor 220v, running in our farm. It’s used to pump water.
I would like to add simple system which would track when motor has started to run and when stopped.
But how to detect it? I have tried with non-invasive SCT-013 device but I think I don’t have enough skills and maybe could not get it working because 3 phases. I don’t want to open motor and do any things inside it because it will cause problems with warranty.
edit: I will continue with those non-invasive current sensors
