As the title states, I'm looking for a portable device that could measure and log real power in three-phase systems/distribution panels.
Ideally it would record up to a weeks worth of data (1 sample per 5 minutes = +- 2000 samples).
Goal is to monitor power "consumption" for several three phase distribution panels, all in a 230/400V 50Hz environment ranging from 50 to 400 Amps.
Obviously the ability to use (different) current clamps is mandatory, so is a cat IV input rating.
Anybody has any suggestions for a portable device that would be suitable?
I am aware of the different din-rail and panel-mount devices, for this instance a portable solution is required.
