<p>An electrical power distribution system includes a dual mode electrical motor/generator, high voltage traction batteries, bi-directional direct current power transmission lines connectable between the dual mode electrical motor/generator and the high voltage traction batteries, first and second isolation contactors including magnetic blow out and connected into the power transmission lines to exhibit opposed polarity and an electrical system controller. In order to deenergize the electrical power distribution system the polarity of current on the bi-directional transmission lines is determined. Once the polarity has been determined the isolation contactor of corresponding polarity is selected to be opened.</p> |
