- Abstract
Air is one of the most widely used insulation medium in power systems. However, up to now there is no any existing gas analysis method used for fault diagnostic based on air by-products detection and analysis. In this paper, a new discharge diagnostic method — gas analysis method based on air by-products (ozone and NOx) is proposed. Firstly, the chemical reaction of air under discharge is analyzed; then a typical partial discharge — protrusion defect discharge is simulated using needle-plane electrodes in a semi-closed test cell. The relations between corona discharge and ozone concentrations are studied. The ozone concentration increases as the maximum PD and applied voltage increase. Meanwhile, the growth rate of ozone concentration is varying against corona discharge under different voltage. These properties imply discharge faults can be detected by measuring and analyzed the gas concentrations.
