A study of the electrical characteristics of the trielectrode plasma curtain (TPC) discharge with different dielectric configuration is presented. The TPC discharge is based on the combination of a DBD discharge and a CD discharge. The TPC discharge includes three electrodes. The DBD is generated between two planar electrodes separated by a dielectric plate and the CD discharge is generated with a third planar electrode facing the DBD electrodes. The DBD electrodes and the CD electrode are separated by an air-gap. It was found that when a dielectric plate is located at the side of the CD electrode, the total voltage drop required for onset of a well-developed discharge increased. A possible explanation for this result is that there are charge deposited onto the dielectric, and this charge induces a reduction of the external field.
