The study presents methods of the calculation of electric field induced in vicinity of an overhead current carrying conductor. Exact method of the determination of the induced electric field bases on the Fourier transform technique, whereas a simplified method uses the concept of complex ground return plane. Exact and simplified methods of the calculation of electromotive force (emf) induced in a loop located under an overhead power line conductor are also presented. The loop is treated as a rectangular loop (two-conductor closed loop) located near the power line horizontal to the earth surface. The exact method bases on the earth return circuit theory, whereas the simplified method allows one to calculate the induced emf under the assumption neglecting earth currents. The methods presented are illustrated by exemplary calculations.
