WebbThis heating is based on the number, location, and proximity of other conductors as well as the losses in the other conductors. The more conductors in the raceway, the greater the … Webbcurrent while in reality there is an AC current causing skin effect and proximity effect. The skin effect is the result of the magnetic field inside a conductor generated by the conductors own current. Fast current changes (high frequency) induce alternating fluxes which cause eddy currents. These eddy currents which add

WebbThe skin effect dominates in the current distribution. Therefore, we can omit the connector proximity effect. Skin Effect To investigate the skin effect we must calculate the current density in a cylindrical conductor.
