Two variations of a 3-D inductive coupling problem in a transmission line right-of-way are analysed with the generalized Partial Element Equivalent Circuit (PEEC) method. This new approach does not rely on the parallelism with the transmission line and permits the determination of the induced current density in underground objects at arbitrary positions and orientations. The adaptions on the basic numerical procedure are presented and discussed as well. A comparison of the obtained results with 2-D and 3-D Finite Element models shows that the proposed approach is able to provide accurate solutions even when employing a coarser discretization mesh. Index Terms-Eddy Currents, electromagnetic coupling, generalized partial element equivalent circuit (PEEC) method, integral equation, transmission lines.
