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.
, V) g3 L8 o3 F- X% z2 T7 r- U
The surge impedance is right:
Zs=sqrt(L/C)

1 O1 ~% j  v! ^3 j- sThe velocity is wrong, it should be:
v=1.0/sqrt(L*C)
as such the travel time would be:
8 e$ U4 A8 E9 V3 g1 J8 B) gt=Length/v=Length/sqrt(L*C)

% F7 f- ^# p% m5 f8 F. t+ N- pBoth 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
