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.

+ k- t- W: A0 b  s7 y8 ?The surge impedance is right:
" E7 J- N# R( a' i( i) M7 }) |$ T/ eZs=sqrt(L/C)
2 W- e+ \4 t& C4 m2 _0 G. {
; h2 F6 U& s) a/ L4 ]+ `3 B' XThe velocity is wrong, it should be:
v=1.0/sqrt(L*C)
as such the travel time would be:
t=Length/v=Length/sqrt(L*C)
5 @& r* _8 A4 Z$ }- Z$ e
& b7 X( M% D/ n. fBoth 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
