Grounding system design using EMTP

This paper addresses grounding systems analysis using EMTP. Grounding systems usually made of conductors embedded in or laid on the surface of the ground, can be modelled using two different methods that simulate the behavior of their components under fast and low frequency excitation. These methods are briefly described in the paper and results obtained from simulations of various grounding arrangements are compared. Comparison with other software packages or experimental data found in literature, are also presented.
