I made some calculations for self inductance for the following 2
cases and mutual inductance for the 2nd case. Any comment/
criticism is welcome.
1. Isolated single busbar
2. 3 busbar as shown below
The self inductance for an isolated single busbar vs frequency
looks like this
For 3 busbar configulation shown in the first figure, the top busbar
is
excited by a current. The self inductance vs frequency is shown
below,
Compare these results with the single busbar case, the inductance
at low frequency is about 40% lower, and at high frequencies, the
inductance becomes zero. IS THIS TRUE?
I welcome any input.
The mutual inductances are
The mutual inductances seem to be reasonable, but again any
input is greatly appreciated.
Thank you for your attention!
