Measuring of Harmonics in the range 2-9 kHz Harmonics up to order 40 (2 kHz at 50Hz) are measured and evaluated according to the standards EN 61000-3-2 and -12. This frequency range includes the emission of typical power supplies or thyristor circuits. Starting from 9 kHz the usual RF EMC standards apply, which have to be regarded beside the low frequent effects... read more...
