A paper published by ACTA Press reports on the results of tests using various electrode types for arc flash testing.

Three electrode systems were tested, and results compared with the IEEE calculations. The types of electrodes used were plane-plane, rod-plane and sphere-sphere electrodes. The effect on arc flash testing was observed for each.

The voltage and current characteristics of each electrode type and for various air gap spacings were obtained graphically by using the data acquired from experiments. The test results are compared with the theoretical results obtained from the formulation given in IEEE 1584 Guide for Performing Arc-Flash Hazard Calculations.

The conclusion was that both the experimental and theoretical results seem to satisfy each other.
