Abstract :
A transfer standard of harmonic voltage and current based on the synchronized sampling technology was developed in NIM China. The working fundamental frequency of the transfer standard is 45 to 65 Hz; the highest order is within 50th; the range is 120 V and 5 A. The accuracy of the harmonic voltage is 30 μV/V (of the fundamental voltage) and the harmonic current is 40 μA/A (of the fundamental current).
