ERRORS IN PHASE ANGLE MEASUREMENTS USING PHASOR SUM AND DIFFERENCE TECHNIQUES.
Abstract
The accuracies of several phasor sum and difference techniques for measuring phase angle, dependent on voltage amplitude measurements, are investigated. It is demonstrated that for the greatest accuracy, different measurement techniques, depending on the size of the phase angle, should be used. Curves are presented for estimating the phase angle accuracy and accuracy of measurement of phase angle increments as functions of the angle size and the precision of the voltage amplitude measurements. The effects of noise, distortion, and 'pickup' on phase angle accuracy are discussed briefly. (Author)
