Calculate average KWH from datalog

Postby rodolphe » Fri Jul 26, 2013 9:41 am

Hi,
We set-up the datalogger on a machine for nearly 9 hours.
The machine is a three phase (400V AC). For info it is a box-wrapper and heat-shrink tunnel.

How can I calculate the average power consumption of the machine in KHW?
The machine plate is written 35KWH. I want to know what is the peak load and the average running load.

I put the logs into an excel spreadsheet attached to this post. I hope you can reply on it so I understand the calculations.

The datalogs were every second.
The readings are in Amps.

Regards
Rodolphee
