Does anyone know if the space has a power meter that can measure power factor? Our existing one only tracks voltage and current.
What voltage levels & power levels are measured? I may have one.
(1) Do you have a current clamp and an isolated (differential probe) for each phase?
Then an oscilloscope (2 inputs per phase) or Data Acquisition card should be able to measure
directly OR follow (2) to (4)
(2) Displacement Power Factor (DPF) = Phase difference between Phase-Neutral Voltage and Phase Current
(3) Use Fourier Transform feature in Oscilloscope OR use Recorded Data to find Total Harmonic Distortion (THD), use Matlab, NUMPY (Numerical Python), Scilab or Octave.
(4) Final Power Factor (PF) = square_root(1/(1 + THD*THD)) * DPF
