A method for operating an electrical power system includes detecting a bridge current magnitude in a rotor-side converter or line-side converter of a power converter, the power converter electrically coupled between a generator rotor and a transformer. The method further includes comparing the bridge current magnitude in the one of the rotor-side converter or line-side converter to a primary predetermined threshold. The method further includes disabling bridge switching of one of the rotor-side converter or line-side converter when the bridge current magnitude exceeds the primary predetermined threshold.
