“…a) dc-Resistance Shunt Calibration R CS dc : The shunt dc-resistance calibration is crucial for absolute and reliable ac current measurement. In general, shunts employed for direct ac current measurements ranging from 10 mA to 100 A have low-ohmic resistance, from 100 Ω to about 7 mΩ, therefore the calibration methods developed for low-ohmic resistance [31] can also be used for purpose calibration of ac shunts [32], also taking the stability, resistance temperature coefficient (TCR) and power coefficient (PCR) influence on shunt dc-resistance value into account.…”

A power frequency modular digital sampling power standard (DSPS) is developed and extensively characterized at Istituto Nazionale di Ricerca Metrologica (INRiM) for accurate electric power measurement with a relative uncertainty (k = 1) better than 8 µW/VA. The calibration strategy employed allows to link its key constituents to electrical quantum standards with a relative uncertainty (k = 1) within 3 × 10 −6 . Comparison measurements against the national power standard at 53 Hz agree well within the respective measurement uncertainties and did not exceed 10 µW/VA at 240 V and 5 A and any power factor.The various novelties introduced make the DSPS a versatile metrological grade measurement setup, which lends well to further improvements and accurate evaluation of electrical parameters involved in power quality measurements. The paper reports the standard, its traceability chain and calibration strategy, comparison measurements and uncertainty budget.
