E2 ≥ U,
Δt ≥ t2-to.рThe method of geoelectrical exploration, which consists in exciting an unsteady electromagnetic field by turning off the current I о in the generator-receiving circuit, determining the maximum amplitude U and the polarity of the self-induction EMF of the circuit, applying voltage E 1 with polarity to the generator-receiving circuit for a period of time from t 1 to t 2 opposite the self-induced EMF circuit, EMF measuring transient electromagnetic fields with a delay Δt with respect to the origin of the point in time t 0 - start off current, which is determined by geoel ktricheskie characteristics studied section, characterized in that in the generator-receiving circuit in the time interval from t 0 to t 1, is supplied the voltage E 2 with the polarity opposite to the EMF source generating current I o, selected time instants t 1 and t 2, achieving lack in the recorded signal of the own oscillatory processes of the generator-receiver circuit, and the value is determined by the value of t 2 , voltage E 2 and the delay value Δt of the reference point is determined from the relations
E 2 ≥ U,
Δt ≥ t 2 -t o .
