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.

) I+ f. p# G- Z5 }! t( j- }The surge impedance is right:
+ [$ G* P% {2 h0 k! h$ sZs=sqrt(L/C)

4 c3 z1 N% P8 F! yThe velocity is wrong, it should be:
v=1.0/sqrt(L*C)
* B' ]6 k" x& h1 ]as such the travel time would be:
, ^# t7 F. c# G9 Dt=Length/v=Length/sqrt(L*C)

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
