Geoelectric Field Estimation during Geomagnetic Disturbances

2019 IEEE Power & Energy Society General Meeting (PESGM), 2019
Geomagnetic disturbances (GMD) occur due to the increase of solar activities, which leads to the variation of earth magnetic field. The variation of magnetic field affects power systems in the form of geomagnetically induced current (GIC), which refers to the quasi DC current flow through transmission lines and transformer windings.

Excitation of fields in geoelectric experiments

Izvestiya, Physics of the Solid Earth, 2007
The paper discusses the premises and possibilities for expanding the experimental base of controlled-source geoelectrics. A nonstationary electric field (E-field, E-mode, and TM-field) and the means for its excitation are examined as a reserve. The appendix presents a compact description of the mathematical apparatus applicable to results of transient ...

Spectrum characteristics of geoelectric field variation

Acta Seismologica Sinica, 2007
The spectrum characteristics of geoelectric diurnal variation and geoelectric storm have been identified by maximum entropy method, based on geoelectric data from seven stations in the Chinese mainland, including Jiayuguan, Changli and Chongming. The study shows that, in geoelectric diurnal variation, the amplitude of the 12 h semidiurnal wave is the ...

The geoelectric field at Davis station, Antarctica

Journal of Atmospheric and Terrestrial Physics, 1995
Abstract An electric field mill is used to measure the vertical component of the geoelectric field at Davis station, Antarctica (68.6°S, 78.0°S, geographic coordinates; 74.6°S magnetic latitude). Local influences on the measurements are determined.

The natural geoelectric field

Proceedings of the 2nd International Conference on Bioelectromagnetism (Cat. No.98TH8269), 2002
Our planet is enveloped by an electric field, which is always present, but varies in magnitude. Even though this has been known for several decades, very little attention is being given to this phenomenon. This global electric field is still not fully understood and provides more questions than answers.

Mathematical Modeling of Some Geoelectrical Fields in Archaeological Exploration

64th EAGE Conference & Exhibition, 2002
P197 MATHEMATICAL MODELING OF SOME GEOELECTRICAL FIELDS IN ARCHAEOLOGICAL EXPLORATION SUMMARY 1 The geoelectrical fields observed on rugged topography (necropolis) are considerably complicated by the effect of unevenness of the earth's surface. This effect can be eliminated in geophysical interpretation.
