Investigation of SF6 decomposition under partial discharge induced by protrusion defect

The aim of this paper is to compare the decomposition characteristics of sulfur hexafluoride, using the study of decomposition by-products, under AC partial discharge of three protrusion defect configurations. This comparison can reveal the influence of quantity, size, and material of the protrusion...
