ABSTRACT: The study of grounding system behavior under lightning condition is a very hard problem to handle. The high frequencies that characterize the lightning phenomena require the use of distributed parameter models instead of lumped parameter ones. This fact makes hard to model and simulate complex earth system architectures and complete power system circuits. Aim of the paper is to develop a distributed parameter model to be implemented in an electromagnetic transients simulator (PSCAD/EMTDC), simple to use in different electric circuits in order to study lightning effects on power system. Computed results are compared to published experimental ones and to those obtained by different models reported in literature.
