Radiation emission reduction in power-line communication systems, by symmetrically and asymmetrically adjustable injection between live and neutral in distribution network

摘要

The method involves simultaneous, symmetrically and asymmetrically adjustable injection between L and N in the distribution network. The feed is also possible between N and PE, LE and PE or L and N and PE. Suitable sensors may measure the minimum field strength or minimum asymmetrical voltage, and converted for automatic adjustment of a voltage divider and phase shifter.
