Abstract :
This paper presents the finite element modeling of multi-conductor grounding connections under external field excitations. The grounding formulation is accomplished using the integrodifferential finite element approach. This formulation of grounding connections is verified by experimental measurement using laboratory scale models. Finally, the modeling technique is used to study eddy current shielding of structural I-beams in arc furnace installations
