In order to investigate the effects of monitor capacitor on the discharge performance of dielectric barrier discharge（DBD） reactors

a self-designed internal and external dual-water-cooled DBD reactor was used to connect different monitor capacitors for experiments. The DBD reactor discharge test system was designed and built. The Lissajous graph and the Monte Carlo method were used to analyze the influences of different monitor capacitor on the discharge parameters of DBD reactor. The results show that

with the decrease of the measuring capacitance

the dielectric capacitance increases and the gas gap capacitance decreases under the same voltage. The power of the DBD reactor

single circle transport charge

burning voltage

effective electric field of the discharge gap and reduced field of the discharge gap increase with the decrease of monitor capacitor. Therefore

different monitor capacitors will affect the discharge parameters of DBD reactor

and matching monitor capacitor has important guiding significance for the accurate measurement of DBD discharge parameters.
