Local Current Gauge: Instrument for Geoelectric Measurements

Resumo

The paper presents the results from developing a new type of geoelectric instrument, a local current gauge. The operational principle of this gauge is based on measuring the electric current density and not the potential difference. The main features of this primary field sensor are described and analyzed. The characteristics of the operational prototype of the gauge are given. The main possible applications of the gauge are considered, including geoelectric and seismoelectric monitoring in a geological environment, as well as geoelectric monitoring and exploration of waterbodies.
