underground substation grounding
(OP)
hi,
anyone familiar with grounding methods for underground applications? the challenge here is to provide effective grounding for a 25kV substation 3km underground.
the soil is highly resistive, and primarly rocks.
any ideas/references/articles would be appreciated.
thanks.

Take advantage of any concrete slab, rebar or foundation (Ufer Ground Electrode) to be interconnected with the ground grid and also connected with the system ground.
