Time Domain Analysis of Ultra-long Cable over Lossy Ground under the High-power Electromagnetic Environment

摘要

The time response analysis of the ultra-long cable over lossy half ground under the high-power electromagnetic environment is discussed. Because of the actual cable is relatively long and the computing resources are limited, the simulation calculation of ultra-long cable is usually difficult. In this paper, the induced current of ultra-long cable over lossy ground under the high-power electromagnetic environment is calculated by using time-domain integral equation (TDIE) method combined with one-dimensional periodic structure theory. The variation of the induced current on the ultra-long cable under different conditions are analyzed.
