Abstract

A high accuracy power measurement system, based on digital sampling techniques, has been developed and evaluated for the power frequencies at UME (National Metrology Institute of Turkey). The system is based on two sampling voltmeters and a phase-locking device. Using of a precision voltage transformer and a current transformer with a shunt resistor, and reducing the synchronizing errors results in an uncertainty of 20 ppm for active, reactive and apparent power measurements for power frequencies.
