I wonder where is the table 3 coming from. Obviously there are mistakes in the table.

, C* e/ Q% q8 I, f" o0 O1 `. oThe surge impedance is right:
9 T8 z$ g6 H0 H4 X- `# M& Z8 UZs=sqrt(L/C)

% q) K; ~) ~' g# q0 }) a  _The velocity is wrong, it should be:
v=1.0/sqrt(L*C)
as such the travel time would be:
5 z' x) C1 x0 `; Tt=Length/v=Length/sqrt(L*C)
4 m+ r7 H: y: D: q0 b
, A) g) u1 K, D! iBoth EMTP and PSCAD/EMTDC, or anyone who does electromegnectic transients simulation, must follow those basic concept, or else they won't work.

正在研究中，有些意思，上面的表格是从emtp－rulebook 找到的啊

搞不懂，应该百度上有介绍的吧
