Three Phase Pump Power Monitor

[lbjstetson]

I'm looking for something to report the power usage every minute or so from two three phase pumps. The voltage would be 208. I've done some research but haven't found anything that'd allow me to send the data to my own source. Any suggestions?

If you use clip-on current probes the three phased-ness and voltage issue pretty much disappears.

This should be usable for your application.

Thanks! Those clip-on sensors are perfect.
