Bus Bar Inductance
Bus Bar Inductance
(OP)
Hi
Could you please give me the formula for the inductance of a single bus bar of L metres. Bus bar of flat shape.
a=width
b=height
Thank you

RE: Bus Bar Inductance
Yes I have visited the site. The formula talks about lambda in the formula but there is an 'l' there.
I have raised this with CDA anyway. DO you have a formula please. I am talking of a single bar uninsulated.
Thank you.

L=31.9?a/b
[sub]
Where
L= Inductance (nH)
?=Conductor Length
a=Dielectric Thickness
b= Conductor Width

L = XL/2Πf
Where:
L = Inductance
XL= Reactance from the table.
f = Frequency (Hz)
Π= 3.1416
RE: Bus Bar Inductance
[(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!
