I wonder where is the table 3 coming from. Obviously there are mistakes in the table.
! I/ M3 ]) @8 ~9 M
5 A2 ^4 g, i2 U3 L. o+ Q/ T$ FThe surge impedance is right:
Zs=sqrt(L/C)
+ U% Y6 M  I( S
6 x. C( |6 o2 a" J8 uThe 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)
8 Q1 l6 U4 D( M1 K) i# r% g  M
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
