Abstract

Research has been conducted on the comparison of the I-V characteristic curve between mathematical study and experiment of the generation of negative DC corona discharge in the Gradient Line-to-Plane (GL-P) electrode configuration. The reason for this research is to calculate the suitability of the corona discharge electrical current between the mathematical and experimental study. The active electrode used has length 2 cm and height 4 cm. This research is conducted with variations in the sharpness angle of the active electrode (θ) 300, 450, and 600 and variations in the distance between the electrodes () 2 cm, 3 cm, and 4 cm. The mathematical formulation of the value of the corona discharge electrical current in the configuration of the GL-P electrode is obtained by using the geometric concept approach, which is the formulation of the capacitance value of the ordinary electrical circuit, with the addition of the multiplication factor value k in the sharp area of the active electrode, because in that area the greatest plasma flow distance is obtained. The value of the multiplication factor  is obtained by fitting the curve between mathematical study and experiments. The I-V curve between the mathematical study and the corona discharge generation experiment has a high degree of similarity with the smallest percentage contacting point of 37.50%.The value of the multiplication factor  is influenced by the sharpness angle of the active electrode shape and the distance between the electrodes.

Abstract

This researchaimed to obtain Dielectric Barrier Discharge plasma discharge characteristics with and without the placement of natural silkBombyx Mori on one of the electrodes. Furthermore, the strength and the water absorption time of the irradiated silk samples will be analyzed.  Plasma discharge is generated by connecting electrodes of point-to-plane configuration with a sheet of glass inserted on the plane electrode at atmospheric conditions. The characterization of plasma discharge, either with or without the natural silk samples' placement on the plane electrode, was performed by increasing A.C.'s high voltage power source to reach arch discharge. Theelectrode spacing varied from 0.7 cm to 2.5 cm with a 0.3 cm increment. Sample irradiation was performed using cold plasma for 5, 15, and 30 minutes respectively. Placing or not placing the natural silk samples on the plane electrode will increase the plasma's discharge current and increase the high voltage. Moreover, increasing the distance between the electrodes and placing the sample on the plane electrode decreases the discharge current. Using Scanning Electron Microscopy, it was found that increasing plasma irradiation time on samples decreases the silk thread'sdiameterand shortening its water absorption time. The strength of irradiated fabric was reduceduntil 15 minutes of irradiation. However, at 30 minutes of irradiation, there was an increase in sample thickness compared to control samples.

Abstract

This research aims to calculate thoroughness among data points and analytical simulation curves in discussing corona discharges' (I-V) characteristics. The electrode construction used is the twin towers with dividing angles to the plane (TTDA-P) model in air, with negative DC polarity. An asymmetrical electrical CCP model in the electrode design uses research variations, including active electrode center clamp angles of q = 300, 450, and 600 and active and passive electrode distances (d) of 0.002 m, 0.005 m, and 0.008 m. The simulation curve comes from the analytical formulation of the reduced capacitance type (inserting a multiplying factor k to the sharp corners of the active electrode), with the simulation program being a Python GUI program. The experimental results produced an appropriate error value (t-test value £0.05) and a high percentage of tangent points value. The best curve was achieved at q = 450 and d = 0.008 m, with a t-test value of 0.0313 and the highest percentage of significant tangent points of 92.31%. For all variations q, there is a tendency that the smaller the value of d (the gap length among two electrodes), the greater the deviation distance between the simulation curve and the data points.
