Type-A grounding system effective length database

A dataset containing effective length values of a subset of type-A grounding system according to the IEC 62305-3 International Standard.

Effective length values are computed in 880 simulations by varying three input parameters (features): soil resistivity, rise-time of the lightning current injected in the middle of the grounding system, and the burial depth of the grounding system.

In the computation procedure soil ionization is disregarded.
