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...
The effect of variation in the switching instant of the output switch of the pulser circuit used in energizing an NEMP simulator on the voltage fed to the simulator and hence the electric field within the working volume of the simulator has been studied. Depending upon the instant at which the output switch closes, the amplitude and the wave shape of the voltage that is fed to the illuminator varies...
Nuclear electro-magnetic pulse (NEMP) simulators which are used in the simulation of transient electromagnetic fields due to a high altitude nuclear detonation are generally excited with a double exponential high voltage pulse. This results in a current distribution on the wires of the simulator and hence a transient electric field in the working volume of the simulator where the test object is kept...
