Abstract/Summary

Abstract The relationship between applied anode voltage, ring anode diameter and distance to specific voltage gradient values was modelled from empirical measurements. The model allowed distance to specific voltage gradients to be predicted. Varying the anode to cathode resistance ratios had a significant effect on the electrical potential of the anode and thus the voltage gradient projected from it. The voltage gradient profile of twin anodes was reduced when they were held in close proximity (<5 m).
