Leakage Current...

Please login with a confirmed email address before reporting spam

Hello all,

I want to study current distribution in a grounding grid buried at depth h=0.8m below the earth surface and its effect on surface magnetic flux density. I am using magnetic and electric field interface in AC/DC module.

Normally when current flows in a grounding conductor part of the current leaks into soil. When i simulate my model i can see the current in the grounding conductors but i cannot see any leakage current in soil.

Could anyone help if i am doing anything wrong in the model.

I am using "amperes's law and current conservation" for the grounding grid and ampere's law for the earth. Moreover i am using magnetic insulation to inject current. The grid conductors are bare (no electric insulation).
