A.1 Theory and analysis of distributed multi-conductor lines and cables
In order to describe accurately the performance of multi-conductor transmission lines, we used in Chapter 3 two-port nodal admittance equations that included the line’s series impedance and shunt admittance matrices. We will now briefly present the theory of distributed multi-conductor lines. The theory also applies to cables.
Consider a multi-conductor line that consists of N conductors. Each conductor, say conductor k, has a self-impedance Zkk, with earth return, and is mutually coupled to all other conductors through mutual impedances Zkj, with earth return. In addition, conductor k has a self-admittance Ykk and is mutually coupled to all other conductors ...
