Water molecules increase the formation of negative oxygen ions which can be meta-stable. These meta-stable ions cannot maintain the excited energy level for extended periods of time, and shed the electron within 100 ps [1]. Though short lived, these ions increase the electron absorption rate and the attachment coefficient (η). As a result, breakdown voltage increases with humidity at power frequency. A second mechanism proposed is based on the direct attachment of electrons to water molecules. Single molecules of water cannot absorb an electron, but clusters of H2O molecules can form negative ions [6-8]. Another mechanism that explains the higher breakdown strength with humidity is an increased number of conversion reactions in which collisions of oxygen ions with water molecules create stable ions [9]. For higher humidities, the breakdown voltage is about 8.5% higher than that obtained for dry conditions at power frequencies (60/50 Hz) and DC. This is true for gaps up to 1 m long [1]. The level of understanding for the VLF/LF bands is not as extensive as that for power frequency and is the motivation of the present project.
