Abstract

The paper reports the results to date from a study to investigate the effect of humidity and frequency on the breakdown of air. Experiments were conducted on Rogowskiprofile uniform field gaps and non-uniform rod-plane gaps ranging from 4 to 52 mm. Results show that uniform field VLF (Very Low Frequency Radio; 10-30 kHz) breakdown voltages decrease with humidity, opposite to that observed at 60 Hz. Nonuniform field breakdown voltages at VLF are lower than those observed at 60 Hz, but have similar trends with humidity. Uniform and non-uniform field breakdown experiments have been completed at 60 Hz for validation.
