pscad与EMTP的理论基础的差异

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.

The surge impedance is right:
Zs=sqrt(L/C)

The 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)

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
