Abstract The three-dimensional earth conductivity structure is modelled by the magnetotelluric data. The three-dimensional geoelectromagnetic fields are calculated based on finite element method using the geomagnetic field data from the magnetic observatories for a specific geomagnetic disturbance. Unlike the traditional modelling techniques, air region and source region are not taken into consideration in this paper. Under this circumstance, the computation results in the earth can also be achieved due to the uniqueness theorem. The geomagnetic field variations during a selected period are applied as the boundary conditions of conductivity model. Combined with the locations of “Sanhua” UHV transmission lines, voltage differences at several substations are shown in the whole period. The geoelectric field at the earth’s surface and the induced currents in different depths are also presented at the moment of maximum voltage difference.
