X/R ration means (line reactance/line resistance)
for short transmission lines it is X/R<3.0
long lines it is >3.0
because long lines length of transmission line is due to
this inductance is more(L directly proportional to length of
line)
for short lines L is low due to this X is low (X=2&#8719;FL)
some value divides low vale it is always high(ex: 1/0.1=10)
