Characterization of Corona and Dielectric Barrier Discharge using Pockels Effect Based Electro-Optic Probe

Résumé

The aim of this paper is to study Pockels effect-based electro-optic sensor to characterize corona and dielectric barrier discharges (DBD). Electric discharges are integral to many industrial processes like surface treatment and air purification. In electrical engineering, partial discharges (PD) have undesirable effects because of their potential to accelerate the insulation aging in high-voltage systems. Consequently, their detection and monitoring necessitate a continuous improvement. This study hones in on the distinctive attributes of Pockels effect based electro-optic sensors for discharge characterization. These electric field sensors are characterized by their wide bandwidth, minimal perturbation, high spatial resolution, and full dielectric properties. Leveraging these features, precise electric field measurements close to the discharges location can be achieved, enabling meticulous exploration of discharge properties. This paper furnishes a comprehensive corona and DBD characterization employing Pockels effect-based electro-optic sensors, furthering our understanding of discharge phenomena and implications. The results show that the electro-optic sensor can be efficiently used for the discharges detection in different configurations and discharge types. The characteristics of the recorded signals depend on the discharge type, so, they can be used for defaults recognition in the insulation systems.
