The window for parameter calculation is shown in Figure 6.6. Since all necessary

rows about line geometry do not have enough room in the corresponding part of

the window, the scrollbar appears on the right; the lower, invisible in Figure6.6,

that is, the table part, is shown in Figure 6.7. It is suggested at rst that one split

three-phase line be considered; it means that the conductors of the same phases

are connected in parallel, supposing even current distribution between them. Then

the conductors of the same phases receive the same numbers (1,2, 3), and the

line is modeled as the three-phase one. The calculation ...
