Study about induced current law by EMP on transmission line

Abstract:

The induced current law on transmission line was studied in electromagnetic pulsed environment. And the variety law including induced current、load voltage、the power were researched according to the following situations: one terminal in short-circuit state and another terminal linked with resistance; two terminals connected with different resistances respectively. The way of non-contact pulsed current injection was taken on the experiment, and the theoretical analysis were done with the transmission line theory model. The results of both ways were identical rule. The results indicated that in electromagnetic pulsed environment the induced current on transmission line and the voltage on the end port resistance had direct relationships with value of load. The dissipative energy by the resistance would reach the maximum value when special resistance values were selected.
