Abstract :
Analytical expressions for determination of the transient pipe-ground resistance and its component-insulation resistance-are obtained. The dynamic range of magnitude values of the magnetic components of the main pipeline field with various conditions of its excitation was analyzed. It is shown that induction sensors satisfy all requirements existing for primary transducers in nondestructive testing and technical diagnostics of underground pipelines
