Unlike conventional methods that analyze phase angles and discharge magnitudes over a fixed interval, PSA evaluates sequences of individual discharge events. For liquid or solid dielectrics, externally measured phase angles are not decisive; local electric field conditions at defect sites govern ignition. Characteristic event sequences and correlations reveal local defects and distinguish single versus multiple discharge locations, supported by experiments and comparisons with numerical simulations.","cbCaikWOPSwRwyFb","https://ap.wps.com/l/cbCaikWOPSwRwyFb","pdf",771374,1,"English","en","# Introduction\n# Phase shift of partial discharge events\n## Electric field and initiation/extinction conditions\n## Sequence correlations and scatter reduction","[{\"question\":\"What problem does Pulse Sequence Analysis (PSA) address compared with traditional partial discharge data analysis?\",\"answer\":\"Traditional analysis focuses on phase angles and discharge magnitudes accumulated over a predefined time interval, while PSA evaluates data sets that include the individual sequence of partial discharge events.\"},{\"question\":\"Why is the phase angle of the externally applied voltage often not a meaningful parameter for partial discharge in dielectrics?\",\"answer\":\"In liquid or solid dielectrics, ignition is determined by the local electric field at the defect site rather than the absolute value or phase angle of the externally applied voltage.\"},{\"question\":\"How does PSA improve defect identification in practice?\",\"answer\":\"PSA reveals characteristic sequences of partial discharge events and uses sequence-correlated parameters to characterize local defects more precisely, distinguishing single and multiple discharge sites.\"}]",1779224441,20,{"code":4,"msg":27,"data":28},"ok",{"site_id":29,"language":21,"slug":30,"title":13,"keywords":31,"description":14,"schema_data":32,"social_meta":83,"head_meta":85,"extra_data":87,"updated_unix":24},105,"pulse-sequence-analysisa-diagnostic-tool-based-on-the-physics-behind-partial-discharges","",{"@graph":33,"@context":82},[34,51,65],{"@type":35,"itemListElement":36},"BreadcrumbList",[37,41,45,48],{"item":38,"name":39,"@type":40,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":42,"name":43,"@type":40,"position":44},"https://docshare.wps.com/document/","Document",2,{"item":46,"name":12,"@type":40,"position":47},"https://docshare.wps.com/document/research-report/",3,{"item":49,"name":13,"@type":40,"position":50},"https://docshare.wps.com/document/pulse-sequence-analysisa-diagnostic-tool-based-on-the-physics-behind-partial-discharges/31221/",4,{"url":49,"name":13,"@type":52,"author":53,"headline":13,"publisher":55,"fileFormat":58,"description":14,"dateModified":59,"datePublished":59,"encodingFormat":58,"isAccessibleForFree":60,"interactionStatistic":61},"DigitalDocument",{"name":9,"@type":54},"Person",{"url":38,"name":56,"@type":57},"DocShare","Organization","application/pdf","2026-05-19",true,{"@type":62,"interactionType":63,"userInteractionCount":4},"InteractionCounter",{"@type":64},"ViewAction",{"@type":66,"mainEntity":67},"FAQPage",[68,74,78],{"name":69,"@type":70,"acceptedAnswer":71},"What problem does Pulse Sequence Analysis (PSA) address compared with traditional partial discharge data analysis?","Question",{"text":72,"@type":73},"Traditional analysis focuses on phase angles and discharge magnitudes accumulated over a predefined time interval, while PSA evaluates data sets that include the individual sequence of partial discharge events.","Answer",{"name":75,"@type":70,"acceptedAnswer":76},"Why is the phase angle of the externally applied voltage often not a meaningful parameter for partial discharge in dielectrics?",{"text":77,"@type":73},"In liquid or solid dielectrics, ignition is determined by the local electric field at the defect site rather than the absolute value or phase angle of the externally applied voltage.",{"name":79,"@type":70,"acceptedAnswer":80},"How does PSA improve defect identification in practice?",{"text":81,"@type":73},"PSA reveals characteristic sequences of partial discharge events and uses sequence-correlated parameters to characterize local defects more precisely, distinguishing single and multiple discharge sites.","https://schema.org",{"og:url":49,"og:type":84,"og:title":13,"og:site_name":56,"og:description":14},"article",{"robots":86,"canonical":49},"index,follow",{"doc_id":7,"site_id":29}]
