Define Short Lines?

For short power lines (up to 50 miles; 80 km),  the effects of the shunt capacitance and leakage resistance are negligible. Hence the line may be represented by the equivalent circuit shown in Figure.

In this case:

 IS = IR (1)

and VS = VR + ZIR    (2)

Comparing equations (1) and (2) with equations

VS = AVR + B IR

IS = C VR + D IR

 the 2-port network constants are:

 A = 1, B = Z

 C = 0, D = 1 = A
