Establishment of AC power standard at frequencies up to 100 kHz

This paper describes the establishment of wideband power standard for traceable measurements of electrical power of sinusoidal signals. The standard is mainly comprised of a set of resistive voltage dividers, a range of current shunts and dual-channel sampling system. The amplitude and phase angle errors of each of the components have been evaluated accurately at frequencies up to 100 kHz. The design of this power standard system has been proposed to cover the voltage ranges up to 600 V, current ranges up to 100 A and frequencies up to 100 kHz. The measurement results of each component have been given in the paper. The total uncertainties of this power standard at current ranges from 1 A to 100 A and at 600 V have also been presented at different measuring frequencies and power factors.
