Summary:In this paper, we proposed an approach to suppress the lightning electromagnetic pulse for receiver by utilizing lightning protection device. The equivalent circuit model of the antenna in receiving state together with the lightning protection device is established for both theoretical and numerical analysis. The combination wave generator (CWG) was used to generate 8/20 μs current injected into the return stroke channel, and the induced overvoltage and energy distribution the lightning electromagnetic wave coupled by receivers have been analyzed. Results illustrate that the induced lightning overvoltage can be well suppressed by using the proposed circuit, and the additional circuit has little effect on the performance of the antenna. The experimental results have good agreement with that of the theory of equivalent circuit.
