3D finite element analysis of conductive coupling problems in transmission line rights of way

Abstract:
The 3D finite element method is applied to compute conductive couplings in a transmission line right of way. The domain under analysis is composed of several underground structures, such as ground wires of high voltage towers, a coated pipeline section and a steel-reinforced masonry enclosure. A non-homogeneous Dirichlet boundary condition is employed to overcome the modeling di_culties of this particular problem. A preliminary test problem to validate this procedure is also discussed.
