IMPROVED DYNAMIC BRAKING GRID RESISTOR CONFIGURATION FOR REDUCING EMI IN AN ELECTRIC TRACTION MOTOR VEHICLE ABSTRACT OF THE DISCLOSURE A dynamic braking grid arrangement for reducing EMI generated by dynamic or partial regenerative electrical braking of an electric traction motor powered vehicle coupled to a wayside power source by a third rail or catenary. The grid arrangement comprises a high-power dissipation resistance grid having a plurality of separately defined resistance elements, each having a generally elongate configuration. Mounting means support each of the grid elements adjacent to and parallel with each other of the elements. A plurality of electrical conduction devices connect the elements into an electrical circuit such that current passes through at least one element in a first direction and through at least one adjacent element in a second opposite direction such that EMI generated by any one element is substantially cancelled by EMI generated by an adjacent element.
