Diagnosis of Partial Discharge Based on the Air Components for the 10 kV Air-Insulated Switchgear [PDF]

open access: yesSensors, 2022
Partial discharge (PD) is a common phenomenon of insulation aging in air-insulated switchgear and will change the gas composition in the equipment. However, it is still a challenge to diagnose and identify the defect types of PD.
