I am following their comments as best I can. If they are using a waveform cutting circuit such as with SCR's then the fundamental current will be shifted in time as compared to one that is not cut up.
I would measure the RMS voltage at 60 hertz, and read the fundamental 60 hertz current. Then multiply these by the COS of the phase angle between them. It does not work to use the RMS values of these waveforms (including all harmonics) to obtain the product.

In-line measurements are being used to verify the setup of the PCE. I don't think they should be using the SCR controller - I would rather they use the variac. The load should be pretty much flat-on resistive for all of the harmonics. They are currently measuring a PF=1. The concerns with the SCR controller are asymmetric +/- switching and noise that could be introduced into the thermocouple channels. Painful to watch sometimes, yes; but they are working through it. I have a chat line open to them.

A triac controller will cause that to happen. Can someone contact them directly and let them know that this may be the hangup. It is painful to watch them chasing this problem. I can not get in touch with them directly. Thanks.
