A system for the accurate characterization of wideband wattmeters, power quality analyzers and PMUs

摘要

A multipurpose system for power measurement is here described. It consists of a six-input high-resolution fast sampling-rate digitizer and suitable transducers. Specific software programs are under development for its use as a system for the accurate measurement of power in a wide frequency band with distorted signals, as an accurate power quality analyzer and as a reference PMU. The present version has been calibrated by an independent procedure and tested in comparison with the primary system for the measurement of electrical power.
