Abstract
Isolated phase bus (IPB)is available for large power plant such as thermal power plant and nuclear power plant to connect between the generator and transformers. Each of three phase bus has an enclosure which is connected electricaly together at the both terminals with a short circuit plate, through which induced current by bus current flows in enclosures.
Some efforts has been made to estimate the current distribution in the short circuit plate by two dimentional analysis of Finite Element Method, but more detail information about the current distribution is needed to develop the larger capacity and improved IPB structures.
This paper presents the results of three dimentional FEM analysis of eddy currents and heat conduction applied to IPB short circuit plates and its modified structure.
