Abstract :
The significance of coupling and interference of external electromagnetic field sources to underground transmission systems has increased due to the development of underground technologies for various applications. This paper discusses the terminal effect of finite length underground cables illuminated by external sources. The equivalent transmission line equations (ETLEs) is used to validate the coupling to the `sheath-earth´ loop of the cables, and conventional TLM is employed to deal with the coupling to the `sheath-core´ loop. One application for conductive coupling of a two-cable underground system of both infinite and finite length cables is addressed and compared with experimental results
