Calculation of Magnetic Field Disturbance Produced by Electric Railway

Tetsuo Tokumoto and Satoru Tsunomura

Abstract

  
   Magnetic field disturbance by leakage current of electric railways is a serious problem for magnetic observations. We can get an exact solution in various situations of the route of railway, distributions of power substations and electric railcars by the method developed herein. The developed method yields a smaller estimating magnetic field disturbance compared with the old method.
