Abstract: With the fast development of global industrialization, high-voltage power lines have become one of the man-made interferences in electromagnetic environment monitoring. In this paper, recent achievements on power line radiations have been summarized, especially by using the satellite electromagnetic observations from DEMETER, such as power line harmonic radiation (PLHR), magnetospheric line radiation (MLR), ELF/VLF emissions, high energetic particle precipitation, etc. And then the coupling models including electromagnetic wave propagation and nonlinear wave-particle interaction have been introduced and discussed. It is aimed to provide more information for the data processing and analyzing techniques in the upcoming China Seismo-Electromagnetic Satellite (CSES-1) mission when the same PLHR signals are dealt with or the weak earthquake-related disturbances are distinguished.

Key words: Power Line Harmonic Radiation, Magnetospheric line radiation, Wave-particle interaction, DEMETER
