Measurements of primary and secondary emission in the supraharmonic frequency range, 2-150 kHz
2015 (English)Conference paper, Presentation (Refereed)
This paper presents an analysis of current emission from low-voltage devices in the frequency range from 2 to 150 kHz. Measurements on an installation with a photovoltaic (PV) inverter together with common household appliances are presented. It is shown to be important to distinguish between emission driven by a certain device (“primary emission”) and emission driven by other devices (“secondary emission”). Measurements show that primary emission can be strongly impacted by neighbouring devices. Moreover it is shown that supraharmonic currents flow between connected appliances and measurements of supraharmonic distortion should be performed on site, inside the installation.
