New electrostatic induction method measures space charge and its effect on AC gas discharge in enclosed air spaces

A new electrostatic induction method allows researchers to measure space charge accumulation and its impact on electrical discharges in enclosed air spaces. The technique derives numerical relationships between induced voltage and space charge, enabling real-time calculation of charge quantities. Characteristic parameters extracted from this data represent charge accumulation and discharge behavior. This method helps analyze discharge stages and effects under various DC and AC-DC superimposed voltages, offering insights into electrical device performance.
