Bus Bar Inductance

There is more to it than a, b and L. Distance to the return path is also important as well as structure and also relative permeability involved. Is it a single bar in empty space or is it one of three bars in a three-phase system? Visit this URL for more ideas:
Check if the enclose site could help

I am no sure what is your application, I hope the enclose info could help.
L=31.9?a/b
Where
L= Inductance (nH)
?=Conductor Length
a=Dielectric Thickness
b= Conductor Width
L = XL/2[Π]f
Where:
L = Inductance
XL= Reactance from the table.
f = Frequency (Hz)
[Π]= 3.1416
L=31.9?a/b

Kantor- The inductance in Henry's per meter of length would be:
[(ur)(uo)Arccosh(D/2a)]/pi for a cylindrical conductor where D is the distance to the return path, 'a' is the radius of the conductor, ur is the relative permeability of the material separating the two conductors, uo is the permeability of free space/air. Since your bus bar is a rectangular shaped object, a fairly close approximation might be obtainable by imagining a stack of cylindrical conductors with a radius half of the width of the bar and adding to the height of the bar, but since the above is based on Ampere's law and some vector calculus you might want to just alter it to your needs. Good luck!
