Summary:
Relationship between breakdown field strength and radiated electromagnetic field intensity was examined in experimental study. As a consequence of the experiment using the system, the breakdown field strength was very high of about 80 MV/m in low voltage discharging of below 350V. And so, the average electromagnetic field intensity is proportion to the breakdown field strength in under the maximum electromagnetic field intensity. In addition, maximum radiated EM field intensity shows approximately 3.5Vp-p respectively, the field radiation due to micro gap discharge has the some limit value in the maximum. And so, the electrode surface effect was confirmed that the received electromagnetic field intensity has a cyclic variation with the cleaning of electrode surface. The radiated electromagnetic field intensity was sudden increase just after the cleaning.
