Switching Surge on an Overhead Line

The surge impedance matrix [ZJ of the source circuit and [ZJ at the right of node r are 

Because of the symmetry of the line surge impedance [Zg], the voltage transformation matrices are 

The modal traveling waves arrive at the receiving end at and the modal waves at the receiving end are given considering the traveling time x and attenuation by (t-xj, 

In Example 2.1, consider transposition of the line with Cj = C2 = 298 m/ is. Solution
