Title :
Improved Reactive Power Measurement through Precision Phase Angle Determination
Abstract :
In the past, the accuracy of reactive measurement has been substantially limited by the precision with which two voltages in quadrature could be generated. A technique employing a commercially available electronic phasemeter has been developed whereby phase angles may be established very precisely. This technique is described in the context of reactive measurements, and other applications are suggested as well.
