Answer Posted / raul
the size of a cable depends upon the maximum dielectric
stress at the conductor surface.........
dielectric stress/potential gradient,g = V/xLOGeD/d
where V= system voltage; x= distance from conductor, D=
diameter of conductor and d= diameter of metallic
sheath....
so max. dielectric stress will b at conductor surface,i.e.
at g(max)= 2V/dLOGeD/d
d value of conductor diameter will be D/2.718 OR LOGe(D/d)
= 1
