Steady-state loss and short-circuit force analysis of a three-phase bus using a coupled finite element+circuit approach

The authors analyze a three-phase bus with steady-state and short-circuit currents using a coupled finite element+circuit analysis method that they had previously developed for rotating machines. The bus consists of nine copper conductors, three in parallel for each phase, in an aluminum duct. This...

Description
Summary:The authors analyze a three-phase bus with steady-state and short-circuit currents using a coupled finite element+circuit analysis method that they had previously developed for rotating machines. The bus consists of nine copper conductors, three in parallel for each phase, in an aluminum duct. This technique is required because the distributions of the respective total phase currents among the parallel conductors are not known a priori. They present the results of both steady-state (frequency-domain) and transient (time-domain) calculations.
