On the measurement of plasma power in atmospheric pressure DBD plasma reactors

摘要

Proposed paper deals with the subject of plasma power measurement in dielectric barrier discharge (DBD) reactors. Four approaches are compared including analytical, electrical, Lissajous figure and comparative methods. Discussion is led regarding measurement sensors, digital oscilloscope time base resolution and measurement capacitor technology. Lissajous curve approach gives results that are very comparable to definition based power calculation. Analytical approach, due to technical reasons, is inadequate, comparative approach gives slightly elevated values with respect to other methods. Measurement capacitor value should be of comparable capacitance to reactors overall capacitance, a pulsed technology capacitor should be used for measurements.
