Determination of the parameters of a shielded busbar with a rectangular monolithic bus under steady-state conditions with sinusoidal current

Abstract

A technique to determine the parameters of a shielded busbar with a rectangular monolithic bus at steady-state conditions under sinusoidal current is suggested. The resistances, inductances, magnetic inductions, induced screen current, and bus voltage are calculated taking into account the sinusoidal current frequency and bus and screen materials. The developed technique is based on electromagnetic field equations, which can be programmed using the Mathcard software for engineering calculations of the busbar parameters during computer-aided design of busbars. The validity of the technique is corroborated by the satisfactory agreement between the results of resistance and inductance calculations and the results obtained using the Elcut computer simulation program.
