Determination of EM coupling on an electrical wiring interconnection system: Application of condensation approaches on cable models

This paper describes a methodology for modeling of EM coupling on an aircraft Electrical Wiring Interconnection System (EWIS). The challenge is to be able to generate an operatory model taking into account the large number of cables and to maintain a reasonable computation time for the evaluation of the distribution of currents at the interface of equipment pieces. For this, a geometrical condensation approach is implemented and tested on a representative test case at aircraft level.
