ABSTRACT:
A low inductance resistor for high current limitation is arranged from a single conductor wrapped in a continuous direction to form a plurality of turns wherein current transport through each of the turns induces a corresponding magnetic field to oppose the magnetic field induced within each next adjacent turn. The resistor finds application within a current limiter unit which employs magnetic repulsion and gas pressure to direct arcs that occur between separating contacts to within the high voltage region of an arc chute. The resistor is connected across the arc to reduce the arc current to a low enough value so that the arc becomes extinguished within a predetermined period of time.
