ntcolor="#b00000"> QS37a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、变压器等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(tgd)和电容量(Cx)，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5KV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（tgd）及介电常数（ε）。mportant;float:none;background-color:rgb(255,255,255);color:rgb(25,25,25);font-family:"PingFangSC",Arial,"微软雅黑","宋体",simsun,sans-serif;font-size:16px;font-style:normal;font-variant:normal;font-weight:400;letter-spacing:normal;line-height:1.9;orphans:2;overflow-wrap:break-word;text-align:left;text-decoration:none;text-indent:0px;text-transform:none;-webkit-text-stroke-width:0px;word-spacing:0px;">
