| # Non-thermal Plasma Parallel DBD Air Dataset |
|
|
| ## Overview |
| This dataset contains experimental time-series measurements from a **parallel Dielectric Barrier Discharge (DBD) plasma system in air at NTP**. |
| The dataset was collected using a digital oscilloscope and includes current-voltage waveforms measurements for plasma discharge characterization. |
|
|
| ## Data Acquisition |
| The experiments were conducted in the Physics Laboratory, Department of Physics, Kathmandu University. |
| Measurements were recorded using: |
| - Digital Oscilloscope: Tektronix TDS 2002 |
| - High Voltage Probe: PINTEK HVP-28HF (1000:1 attenuation ratio) |
| - Current Measurement: 10 kΩ shunt resistor |
|
|
| All measurements were performed under controlled DBD plasma conditions in air at NTP. |
|
|
| ## Experimental Setup of the DBD System |
| The dielectric barrier discharge (DBD) system consists of a parallel electrode configuration placed inside a transparent polycarbonate reaction chamber. The system is designed for plasma generation in air under normal atmospheric pressure conditions. |
| The setup includes the following components: |
|
|
| - (1) Parallel electrodes for plasma generation |
| - (2) Dielectric barrier sheet separating the electrodes |
| - (3) Ballast resistor |
| - (4) Shunt resistor used for current measurement |
| - (5) High voltage probe for voltage measurement |
| - (6) Oscilloscope probe for signal acquisition |
| - (7) Digital oscilloscope for waveform recording |
| - (8) Reaction chamber (polycarbonate enclosure) |
| - (9) High voltage AC transformer (50 Hz operation) |
| - (10) Ground connection |
| - (11) Computer interface for data acquisition and monitoring |

|
|
| The DBD electrode configuration was placed inside a transparent polycarbonate chamber (35.7 cm × 20.0 cm × 15.0 cm). An AC high voltage of 15.65 kV at a frequency of 50 Hz was applied across the electrodes. The separation between the upper electrode (7.53 cm × 4.97 cm × 0.47 cm) and the grounded electrode (7.54 cm × 4.99 cm × 0.48 cm) was 6 mm. The dielectric barrier consisted of a polycarbonate plate (13.0 cm × 10.0 cm × 0.197 cm). A polycarbonate sheet was inserted between the two electrodes to serve as the dielectric barrier. |
|
|
| The discharge was generated between two rectangular parallel electrodes. The oscilloscope probe was connected across a 10 kΩ shunt resistor for current estimation. The voltage and current waveforms were monitored and analyzed using a digital oscilloscope. In this work, a high-voltage AC supply operating at 50 Hz was used. |
|
|
| ## Dataset Structure |
| The dataset consists of multiple experimental conditions labeled by numerical values (100, 110, 120, ..., 220). Each condition represents a different oscilloscope division of the DBD system. |
