Abstract
The paper describes a standard system for traceable measurements of electrical power of sinusoidal signals at voltages up to 1000 V, currents up to 20 A and frequencies from 40 Hz to 200 kHz. The system uses thermoelectric effects to relate the alternating power to that of known dc signals. It is comprised of a thermal power comparator, inductive and resistive voltage dividers and a range of wideband current shunts. The performance of each of the components has been evaluated through traceable measurements, in terms of fundamental standards. The standard uncertainties range from less than 5 muW/VA at power frequencies to 60 muW/VA - 250 muW/VA at 200 kHz.
