I deal with current and voltage readings and have to manually derive watts VAr etc. It should not be too big a deal to add in power calcs for a pair of nominated analogue channels.
You would need to allow for Voltage scaling, and Current scaling factors for the analogue channels.
I.e. 1 volt in Chan 1 (secondary, as read by Logic) = 100 Volts primary.
1 Volt in Chan 2 (secondary as read by Logic) = 100 Amps primary.
The power calcs are well published on the net.
Outputs would be:
And possibly energy WattHrs
