modelLineConstantImpedanceFault
Transmission line with constant impedance and fault in intermediate position
Extends from Electrical.BaseClasses.TwoPortAC (Base class for two-port AC components), Icons.Line.
Information
Transmission line with constant series impedance R+jX and constant shunt admittance G+jB.
Implemented as a child class of PiNetwork, where Ya=Yb=(G+jB)/2 and k = 1, see the corresponding documentation.
