Abstract

A procedure for the analysis of multiconductor busbar systems under steady-state AC conditions is presented. The method is based on a lumped parameter approach under the hypothesis of magnetic linearity. The model involves a matrix of self and mutual impedances deduced from electromagnetic field solutions including eddy current effects. The matrix, inserted into circuit equations, leads to current sharing evaluation under the studied operating conditions. As an example, a 4000-A busbar system having three subconductors per phase is analyzed
