| Zusammenfassung |
| Whereas geomagnetically induced currents are a source of problems for
technological systems mainly at high geomagnetic latitudes, strong
geomagnetic disturbances can have quite strong effects even at mid-latitudes.
This paper deals with the analysis of the pipe-to-soil (P/S) voltage measured in
oil pipelines in the Czech Republic during the Halloween magnetic storms
in 2003. It is shown that the simplest - plane wave and uniform Earth-model of
the electric field corresponds well to the measured P/S voltage. Although the
largest amplitudes of the geomagnetic field were reached on the onset of the
geomagnetic storm, large voltages were also induced in the main and recovery
phases due to Pc5 oscillations. |
