Generally,　the　high-speed　oscilloscopes　are　selected　to　acquire　the　real-time　data　on　site　for　partial　discharge　diagnostic　testing　and　monitoring　in　Air-Insulated　Substations　(AIS).　However,　it　has　some　disadvantages,　such　as,　the　high　cost　and　the　inconvenience　to　carry　and　install.　In　this　paper,　we　proposed　an　agile　software　defined　radio　(SDR)　platform,　the　AD-FMCOMMS5-EBZ　mounted　on　the　Zynq　®　-7000　SoC　ZC706　evaluation　kit,　as　a　good　solution.　We　will　examine　the　advantages　in　the　platform　that　allow　developers　to　quickly　prototype　partial　discharge　diagnostic　testing　and　monitoring　in　Air-Insulated　Substations.　The　tools　required　in　this　case　are　MATLAB　®　and　its　support　packages.　As　a　real-world　example　of　the　procedure,　we　will　prototype　a　platform　that　determinate　partial　discharge　position　directly.　The　final　results　verify　functionality　and　performance　of　the　location　determination　algorithm,　and　show　that　the　accuracy　of　the　algorithm　is　acceptable.　©　2022,　ICST　Institute　for　Computer　Sciences,　Social　Informatics　and　Telecommunications　Engineering.
