I want to calculate power - I know amps, voltage but not power factor - on a single phase max 50A circuit. There is a mechanical KW meter at the in-feed, could I log data for a month say, compare and work out an average PF...? Yes it will vary, but this is for fun (home automation) not industrial. Or, are there PF meters like this: https://www.laurels.com/transmitter-phase.php that would work as a PLC input?
Secondly, what is the best way to totalise; in the PLC or SCADA (Ignition)?
