Preliminary verification tests of mains harmonics’ generator

Environmental protection affects strongly the subject of power quality. Currently there are a lot of quality analyzers in use. Power and energy quality analyzers used in many fields should be calibrated in qualified competent laboratories. The heart of verification measurement system in calibration laboratory is precision harmonic signal generator, which should be calibrated and verified periodically. This article shows preliminary results of calibration process of harmonic generator in the field of frequency and voltage. The schemes and analysis of results are also presented. The method of calibration was invented and tested in the laboratory conditions in National Institute of Telecommunications.
