Electrical field on the surface of condactive polarizable mediem on venner and equatorial arrays

Abstract

The scientific aim of the paper is electrical field transient research above conductive polarizable Earth for the equatorial areas of the source - electrical line. To use for this purpose a number of one-dimensional models in which the IP is created on the upper and down section parts which separated by high resistive screen. To show the difference in the signal of the transient process on measuring lines, with galvanic and inductive excitation of the induced polarization predominating for visual allocation of the time range when in general the signal of the transient process is dominated by the formation signal, galvanically induced polarization (IPG), and induction-induced polarization (IPI). The study is based on the results of solving a direct problem of pulsed electrical reconnaissance with earthed lines, in which the IP is taken into account by introducing the frequency-dependent resistivity by the Cole-Cole formula and transient (∆U(t)) visualization.
