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

Geometrical and Electrical Configuration

Chamber dimensions: Polycarbonate (35.7 cm × 20.0 cm × 15.0 cm)
Electrode configuration: Parallel plate electrodes
Electrode material: Copper
Upper electrode dimensions: (7.53 cm × 4.97 cm × 0.47 cm)
Grounded electrode dimensions: (7.54 cm × 4.99 cm × 0.48 cm)
Electrode gap: 6 mm
Dielectric barrier: Polycarbonate plate (13.0 cm × 10.0 cm × 0.197 cm)
Applied voltage: 15.65 kV AC
Frequency: 50 Hz
Shunt resistor: 10 kΩ

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.
