EURAMET #1172: Bilateral three-phase AC power and energy comparison at power frequency

Research output: Book/ReportReport


The report summarizes the results of EURAMET project # 1172 on a bilateral comparison of power and energy measurement capabilities in MIKES, Finland and SP, Sweden in 2010-2011. A portable three phase reference energy meter was calibrated by the two institutes. Both active and reactive power as well as active and reactive energy measurements were compared. The expanded comparison uncertainty (k=2) ranged from 0.015 % for active power up to 0.06 % for some reactive power measurements. All measured values agreed within the expanded comparison uncertainties.
