Abstract: With the rapid development of China's national economic construction and the increasing complex of the power environment, power frequency interference effects on the geo-electric field are becoming more and more serious. Power frequency interferences produced by power supply system are a kind of electro-magnetic interference in the geo-electric field observation in China. We first briefly introduce the method of geo-electric field observation. Second, we analyze in detailed the principle, methods, effects and the mechanism of power frequency interferences in the geo-electric field observation. And then, we systematically investigate suppression method for power frequency interferences and its particularity in geo-electric field observation. Finally, the effects of power frequency interferences suppression is discussed, combined with the actual geo-electric field observation.

Key words: Geo-electric field, Power frequency interference, Interference suppression
