Sparkover Voltage of Sphere Gaps

Factors Influencing the Sparkover Voltage of Sphere Gaps: Various factors that affect the sparkover voltage of a sphere gap are: nearby earthed objects, atmospheric conditions and humidity, irradiation, and polarity and rise time of voltage waveforms. 1.Effect of nearby earthed objects: The effect of nearby earthed objects was investigated by Kuffel by enclosing the earthed …
