Aiming　at　the　problem　of　low　efficiency　and　poor　performance　in　partial　discharge　locating　for　a　row　of　switchgears,　this　paper　proposes　a　locating　method　based　on　wireless　synchronization　technology.　By　placing　TEV　monitoring　devices　on　multi-switchgear　data　of　partial　discharge　could　be　get,　then　wireless　network　is　used　to　synchronize　the　data　of　multiple　sensors,　after　that　the　partial　discharge　signals　of　multi-switchgear　at　the　same　time　could　be　get　and　their　amplitude　could　be　used　for　comparison,　finally　the　purpose　of　＇locating　to　single　switchgear＇　could　be　achieved.　Through　hardware　design　and　synchronization　logic　locating　is　realized.　Then　the　locating　effect　of　this　method　is　researched　by　placing　artificial　defect　on　different　place　in　switchgears　and　verify　locating　results,　so　that　the　accuracy　and　effectiveness　of　this　method　could　be　proved.　©　2020　IEEE.
