This paper describes how to forecast copper losses in a bus bar, composed of thin copper layers and several access points. The main difficulties are, first to determine current path and associated electrical characteristics, and second to propose electrical equivalent circuits of the bus bar, allowing copper losses representation. For bus bar electrical modeling, the choice of an integral method, PEEC method, is justified. Then, several equivalent circuits are proposed and their validity for copper losses computation discussed.
