The lossless part can be described in three ways
6 z6 J( ^0 t3 e! ~ V6 W- C5 D) I! h 0. Inductance L' in [mH/m] if Xopt=0 or in [ohm/m] if Xopt=power frequency

Xopt. and Copt. are set in menu: ATP|Settings/Simulation.- ^+ q# B4 p- A$ v$ r6 m
The user can choose conductance modeling G=0 (the usual case) and G=R*C/L (distortionless)

Xopt在setting里面设置,如果用的是atpdraw的话 |
