Corona Discharge Images under DC and AC voltages

This dataset includes corona discharge images under AC, + DC, and - DC voltages. To generate corona discharge, three types of electrodes were used. These are the conical rod - plane, the hemispherical rod - plane, and the hemispherical rod - hemispherical rod. One electrode was connected to the high voltage, and the other was connected to the ground potential. A digital single-lens reflex (DLSR) camera was used to capture corona discharge images from corona inception to the gap breakdown. The corona discharge light patterns changed depending on the voltage types, the voltage level, and the electrode types. The experiments were conducted under atmospheric air conditions.本数据集收录了在交流电、正直流电和负直流电电压下产生的电晕放电图像。为生成电晕放电，采用了三种类型的电极，包括锥形杆-平面电极、半球形杆-平面电极以及半球形杆-半球形杆电极。其中一电极连接至高压，另一电极则接地。采用数码单镜头反光相机（DLSR）捕捉从电晕形成至间隙击穿的整个电晕放电图像过程。电晕放电的光学模式随电压类型、电压等级以及电极类型的不同而发生变化。实验在常压空气环境下进行。
