Hi Trystan, I was thinking of using the zero-crossing of the current waveform and the voltage-waveform, then measuring the time diffrence - is fairly simple to then calculate the power-factor. On smaller loads, like switching power-supplies or "CFL" lights, the power factor is not nearly as important as with larger loads. I have some experience with power-factor-correction at installations like saw-mills and the like ( 500 KVa supply ). Charles
