Abstract :
The induced voltage on the communication line near power lines is calculated by virtue of the CDEGS software. When power lines fault, the fault current flows through the power lines and the ground lines. The influence of the ground lines is analyzed through a test on practical power lines. In addition, a transient analysis is carried out using the Fourier transformation with the modeled fault current.
