BDAT-B型高压电容电桥
主要用于测量高压工业绝缘材料的介质损失角的正切值及电容量。其采用了西林电桥的经典线路。
主要可以测量电容器，互感器，变压器，各种电工油及各种固体绝缘材料在工频高压下的介质损耗( tg)和电容量( Cx)以，其测量线路采用“正接法”即测量对地绝缘的试品。
由于电桥内附有一个2500KV的高压电源及一台高压标准电容器，并将副桥和检流计与高压电桥有机的结合在一起，所以本电桥特别适应测量各类绝缘油和绝缘材料的介损（tg）及介电常数（ε）。
 桥体本身带有5Kv/100pF标准电容,测量材料介损更为方便。
桥体内附电位**及指另仪，外围接线及少。
 桥体采用了多样化的介损测量线路。
