Brown, G L

This note is concerned with the problem of predicting the bulk current that will be generated in an insulated cable, lying on the surface of the earth, by an EMP field. The point of departure for developing a solution to the problem is a set of differential equations developed by E. D. Sunde. The work done by Putzer, Brown and Schwartz in obtaining a solution for the currents in the terminal loads of such a cable is summarized. This note also presents the derivation of some simplified equations for estimating the maximum current that could be generated in a surface cable by an EMP. Such an estimate is useful in determining how much EMP protection to apply. The derivation consists of making a series of approximations and assumptions.
