產(chǎn)品介紹：

XGJF-2002型局部放電檢測儀

        廣泛適用于變壓器、互感器、高壓開關(guān)、氧化鋅避雷器、電力電纜等各種高電壓電工產(chǎn)品的局部放電的測量，產(chǎn)品的型式試驗(yàn)，絕緣的運(yùn)行監(jiān)督等。本儀器檢測靈敏度高，試樣電容覆蓋范圍大，適用試品范圍廣，輸入單元（檢測阻抗）配備齊全，頻帶組合多（九種）。儀器經(jīng)適當(dāng)定標(biāo)后能直讀放電脈沖的放電量，指針式表頭和數(shù)字式表頭同時(shí)顯示，指針式表頭能按需要方便地選擇對數(shù)刻度或線性刻度指示。本儀器是電力部門、制造廠商和科研院所等單位廣泛使用的實(shí)用的局部放電測試儀器。
