Precision zero crossing for mains metering
Precision zero crossing for mains metering
(OP)
Good afternoon,
I've done a few searches on the forum but nothing relevant came back.
I need some advice regarding a zero crossing circuit that will be used to measure phase shift for mains supply. I'm trying to have a precision of at least 1 degree electrical. For 50Hz that is aprox 50us pulses, so i think comparators can be used. Anybody used them before for this purpose? Can you please post some circuits that you think will work ?

Your fixed frequency will be an advantage.
