In the process of measuring power factor, I wish to use a C.T. and a P.T., how do I determine the errors that these devices will introduce to the signals I am trying to measure?
What are accepted methods of measuring PF? How do I minimise these errors?

I am currently trying to understand how Power Factor effects the output of a welding transformer. I understand how it is calculated, in terms of difference of phase angle between volts and amps, but how does the voltage affect the output? A transformer relies upon a changing magnetic field on...
