B102是B系列中一款用于測量絕緣故障引起的接地漏電電流的型號。它可以在故障發(fā)生之前定位和診斷故障，從而避免安裝關(guān)閉。它是專門為在大電流電路上定位小電流故障而設計的。B102測量500μA以上的差分或泄漏電流，并可用于連續(xù)使用（400A）時測量高達200A的電流。B102有兩個測量范圍：1mv/maac或1mv/aac。作為一種漏電流檢測儀，B2可用于單相或多相系統(tǒng)，無論電流是否同相、平衡或不平衡。B2可以簡單地用作高精度電流探針夾持器。B2的鉗口開口為100mm，動態(tài)測量范圍為500μA至200A，是一種多功能儀器，在分析失衡電路、泄漏電流和接地回路電流方面非常有用。當與人工中性點結(jié)合使用時，b2可同樣用于測量無中性點的三相電路上的故障電流。
