As I have told you, No 理论基础的差异.

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

The surge impedance is right:
6 b2 T8 M6 M  e- U4 cZs=sqrt(L/C)
5 y9 q& y2 w: x
The velocity is wrong, it should be:
) s" Y5 a0 R, j0 v1 Lv=1.0/sqrt(L*C)
4 m6 W0 Y$ o% L$ `1 v  i  Fas such the travel time would be:
  R3 Q' f% v2 it=Length/v=Length/sqrt(L*C)
% I' G- f+ H4 D  }
Both 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
