Hong-Kyu Kim, Yeon-Ho Oh, and Se-Hee Lee, ¡°Calculation of Temperature Rise in Gas Insulated Busbar,¡± Journal of Electrical Engineering & Technology, Volume 4, No 4, pp. 510-514, December 2009. Abstract This paper presents the coupled analysis method to calculate the temperature rise in a gas
insulated busbar (GIB). Harmonic eddy current analysis is carried out and the power losses are calculated
in the conductor and enclosure tank. Two methods are presented to analyze the temperature distribution
in the conductor and tank. One is to solve the thermal conduction problem with the equivalent
natural convection coefficient and is applied to a single phase GIB. The other is to employ the computational
fluid dynamics (CFD) tool which directly solves the thermal-fluid equations and is applied to a
three-phase GIB. The accuracy of both methods is verified by the comparison of the measured and calculated
temperature in a single phase and three-phase GIB.
