AbstractHarmonic power analyzing instruments are used in the electrical power industry to monitor the power quality of the power supply network, under sinusoidal and non-sinusoidal waveform conditions, including EMC verifications. The demand at National Metrology Institutes (NIM) to evaluate harmonic power analyzers under non-sinusoidal waveform conditions has increased from year to year, in particular at NIM China and also at the provincial metrology institutes and similar technology institutes. At NIM China, like many other NMIs, a harmonic power standard has been developed in 2006, and has been used to provide such calibration service. In the meantime some international comparisons have been completed, including a Key Comparison is being organized. Also, the quality and performance of the available measuring instruments in the market have improved. Based on experiences of calibrations over a period of almost ten years, including that of international comparison, a test protocol is proposed for the calibration of harmonic power analyzers. This test protocol proposal is to be submitted for approval to the China's domestic technical institutes. Some main considerations of the test protocol are discussed in this paper.
