A New Precision Digital Phase Meter and Its Simple Calibration Method

Abstract

A digital phase meter (DPM) for power frequencies with a very low measurement uncertainty of 1 ¿rad was developed at Japan Electric Meters Inspection Corporation (JEMIC) to establish a power and energy calibration system. We also developed a phase meter calibrator (PMC) for calibrating the DPM. Since the DPM and PMC are synchronized with a single clock, the… (More)
