Application95 Inductance analysis of busbars

A busbar is a conductor used in high-voltage, high-current sections that connect a power source to each section, mainly to a switchboard or control panel.
The inductance of bus bars is considered to be one of the factors causing device breakdown due to the generation of surge voltage in electrical equipment, and its reduction is required. Femtet makes it easy to determine inductance from a magnetic field formed by an electric current.
In this case, the frequency characteristics of the inductance and the current distribution of the conductor are introduced.
