Simpeg direct current resistivity
Webb12 nov. 2024 · The first main requirement of a DC-resistivity system is to inject a source current into the ground. The most straightforward way to inject current is to attach a high-voltage source using high-quality electrical wires to two metal electrodes. WebbIn circuits with only inductive loads, i.e., in perfectly conducting grounds, eddy current lags the voltage with a phase shift of 90° ( rad) and, therefore, with a phase lag of 180° with respect to the primary magnetic field.
