A Study of Corona Discharge Rate and Energy Loss in Spark Gaps

A study was carried out on the corona discharge rate and energy loss occurring within artificial cavities. An air gap with metallic electrodes was utilized to simulate the ionization sources within a cable. The corona discharge rates, obtained with varying gap spacings under different vapor pressures, showed marked deviations from the idealized behavior. thhe calculated tangent δ values, in terms of the pulsed corona energy loss for the tested cable-cavity combinations, were found to agree reasonably with those determined experimentally.
