Can someone guide me on how to determine the influence of substation GPR on a nearby pipeline?

Hi all can anyone guide me how to calculate the GPR at the gas pipeline nearest to the substation when a fault occurs in the substation.

If no OHLine is close then the GPR fades exponential with the distance.See, for instance, the attached table from ENA EREC S34
