<BR>Hello everyone,
<P>I made some calculations for self inductance for the following 2
<BR>cases and mutual inductance for the 2nd case. Any comment/
<BR>criticism is welcome.
<P> 1. Isolated single busbar
<BR> 2. 3 busbar as shown below
<P><IMG SRC="../../../../Lidu/Inductance/bus.gif" HEIGHT=318 WIDTH=320>
<BR>The self inductance for an isolated single busbar vs frequency
<BR>looks like this
<BR><IMG SRC="../../../../Lidu/Inductance/self.gif" HEIGHT=283 WIDTH=352>
<P>For 3 busbar configulation shown in the first figure, the top busbar
is
<BR>excited by a current. The self inductance vs frequency is shown
below,
<P><IMG SRC="../../../../Lidu/Inductance/self_3bar.gif" HEIGHT=285 WIDTH=352>
<P>Compare these results with the single busbar case, the inductance
<BR>at low frequency is about 40% lower, and at high frequencies, the
<BR>inductance becomes zero. <B><FONT COLOR="#CC0000">IS THIS TRUE</FONT></B>?
I welcome any input.
<P>The mutual inductances are
<P><IMG SRC="../../../../Lidu/Inductance/mutual_3bar.gif" HEIGHT=282 WIDTH=353>
<P>The mutual inductances seem to be reasonable, but again any
<BR>input is greatly appreciated.
<P>Thank you for your attention!
