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.
0 N$ Y  n: W- X; ~/ P
6 `0 ]7 U% V8 X3 ]The surge impedance is right:
* O7 t% C  l) W0 eZs=sqrt(L/C)

! a6 W) D1 Q7 u2 H8 KThe velocity is wrong, it should be:
; b1 Z5 n2 b  x" e/ jv=1.0/sqrt(L*C)
: I2 T" `6 e5 s! i! G# @as such the travel time would be:
t=Length/v=Length/sqrt(L*C)
; s# l; i; R0 j: g
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
