Simulating Ground System (coupling conductors)

[tbir]

Im trying to design an equivalent circuit for a grounding system where a buried bare horizontal conductor is seperated by 10 m from a few ground rods which are each seperated by 60 m. They run parallel to each other.
x 60m x x x
|
10m
|
----------------------------------------

To help describe the circuit the x's represent the ground rods and the --'s represent the horizontal conductor. I know the equiv circuits for the ground rods and horizontal conductor buried in the ground but I was wondering how these would be coupled together using R,L, and C's . What Im trying to do is simulate a lightning strike to the horizontal conductor and see how it would effect the equipment connected to the ground rods.

Thanks

Suggestion: R, L, C parameters or variables may be used; however, the most significant parameter is the resistance that is often used in industry standards, and Electrical Safety Codes.
