A very fast power factor calculation method

This paper describes a very fast method of calculating the power factor (p.f.) for a power line. Only two progressive samples of the current and voltage are required to execute the measurement. A phase locked loop (PLL) frequency multiplier scheme allows for an accurate measurement independent of th...

Summary:This paper describes a very fast method of calculating the power factor (p.f.) for a power line. Only two progressive samples of the current and voltage are required to execute the measurement. A phase locked loop (PLL) frequency multiplier scheme allows for an accurate measurement independent of the power line frequency fluctuation.
