论文简介    Light　emitted　from　partial　discharges　(PDs)　in　SF　6　gas　is　investigated　in　the　view　point　of　insulation　status　diagnostics.　Light　intensity　and　integral　spectrum　of　PD　are　proved　to　have　significant　correlations　with　PD　activities　and　the　involved　dielectric　interfaces.　Based　on　synchronous　light　pulse　detections　in　ultraviolet　(UV),　visible　(VIS)　and　near-infrared　(NIR)　regions,　the　multispectral　stochastic　PD　diagnosis　is　realized　with　more　information　beyond　the　conventional　PD　detections.　The　optical　PD　detection　is　also　compared　with　ultra-high　frequency　(UHF)　PD　detection　and　acoustic　emission　(AE)　PD　detection　in　term　of　linearity,　sensitivity　and　statistical　property.　Beyond　that,　a　clustering　analysis　is　performed　on　the　multispectral　photon　counts　of　different　conditions　by　quantifying　them　in　a　ternary　diagram　where　some　distinguishable　regions　emerge　for　PD　recognition.
