Measurement and analysis of power frequency magnetic field in substation of Jing-Shi Passenger Railway Line

In this paper, on the basis of the power frequency magnetic field data measured in substation, first, the test data analysis is given, then the overall distribution characteristics of power frequency magnetic field in substation is given. Reference the judge basis(DL/T 799.7-2002) of power frequency magnetic field intensity in substation work sites, the environment of power frequency magnetic field in substation is estimated, which showed that the intensity of power frequency magnetic field is in the permission range under a special industrial environment.
