Abstract :
The interaction of transient electromagnetic field due to HEMP with multicore buried power distribution cables is studied in this paper. Using transmission line analysis, the induced current on the shield of the cable is computed. The cable transfer impedance is used to find the coupled current in the inner circuit. The variation of the current induced on the inner conductor as a function of the distance along the length of the cable is computed. The influence of the depth of burial of the cable on the induced current is evaluated to determine the soil attenuation effects.
