BE]--transmission lines, connected to the substation equivalent surge impedance.
The network consists of substation with capacitance C = 1nF and three transmission lines with phase-phase channel surge impedance [Z.
Travelling wave induced voltage front time delay mainly depend on network topology, line surge impedance and substation capacitance.
In proposed tower model, three vertical parallel conductors connected to grounding resistances of 10 [OMEGA] at their bottom and to surge impedance of 1500 [OMEGA] at their tops have been considered, as depicted in Figure 5.

It is important to notice that whenever one mode is selected, the opposite mode is connected to its surge impedance
Load] = Motor surge impedance to traveling waves with fast rising time and
The cable impedance presents definite measurable surge impedance [Z.
The essential difference between the electrical data of overhead lines and cables is the surge impedance
of their conductors to earth.
Inductivity of this equipment together with surge impedances of the lines form transfer function on the area of frequency domain that is far enough from spectrum area of fast transients.
The main adaptive parameters are: length of the branches, ground resistance, surge impedances and modal matrixes.
