[Special Talk] Study of emitting and inducting phenomenon relating to telecommunication cable
Nobuo Kuwabara (KIT) EMCJ2016-115
Abstract (in Japanese) (See Japanese page) 
(in English) I studied the disturbance emitting from telecommunication cable and the over-voltage inducting at telecommunication line end. This report describes my studies relating this subject. These are 1) lightning surge inducing at subscriber line ends, 2) telecommunication signal component emitted from overhead cable, 3) differential mode signal component emitted from UTP cable, and 4) magnetic field strength emitted from indoor power distribution line.
In the study of lightning surge, the lightning surge was calculated by using Fourier transform. The result showed that the difference of lightning surge waveform between subscriber end and office end was caused by the difference of grounding system. In the study of the emitted telecommunication signal from cable, the relation between the signal level and the emitting magnetic field strength was investigated. The results showed that the influence to broadcast was small if the common-mode current of telecommunication equipment port was lower than the limits. Moreover, in the study of emitted electromagnetic field from UTP cable, the analysis using F-matrix indicated that the emitting electromagnetic field strength could be calculated by this method up to 2GHz. In addition, the analysis using the moment-method indicated that the dependence of number of pair was different by the configuration of cable. Finally, the study of the emitted magnetic field strength from indoor power distribution line showed that the method of using F-matrix was effective to analyze it.
