Abstract :
In this paper, the influence of mobile signal in UHF PD monitoring is discussed in types of substation in China. To find the solving, the GSM mobile signal´s spectrum are measured and analyzed both in laboratory and onsite. The results show that the mobile signal´s spectrum is broad when the phone signal is emitted. It is hard to avoid this interfere only by using narrow measuring band. At the same time, the GSM mobile signal´s transmission characteristic in GIS was simulated in our model under laboratory conditions. In brief, our findings are discussed through two projects. The results show our finding is available and effective
