The effect of oxidation on the high-frequency resistance of aerial wires: with a note on measuring the resistance of thick wires

Measurements are made on thick solid and stranded wires to ascertain the effect on their high-frequency resistance of the oxide film formed by weathering. It is found that the weathering produces no sensible effect, under either dry or wet conditions. The several methods of measuring high-frequency resistance are compared in respect of their suitability for determining the resistance of stout straight conductors.
