The Relationship between Radiated EM Field Intensity and Electrode Condition due to Micro Gap Discharge

Abstract

The breakdown field strength and radiated electromagnetic field intensity due to micro gap discharge were examined in experimental study. As a consequence, the radiated electromagnetic field intensity has inverse proportion to discharge voltage below about 800V breakdown. And so, the relationship between radiated electromagnetic field intensity and discharge voltage has indefinite dispersion in the wide gap discharge of about over 0.04mm gap length. It was confirmed that one of cause of the dispersion is an effect of surface condition in the discharge electrode.
