My question is this:

After finally pinning down the boss I’ve eventually convinced him we can have our equipment replaced!

We had a data logger record our equipment for one week (voltage, currents, KW, KVAr, KVA ect) and decided to use the data to compile a report to indicate the size required for install.

The question is about the current waveform results:
Do we use the maximum average RMS value (the true effective value of the waveform) or the maximum max recorded value (the amplitude) to size are equipment.

I am as you can appreciate concerned about under sizing equipment due to fault or effectively over sizing and costing the company unnecessarily

Many, many thanks in advance for your thoughts and suggestion on this!
