执行标准： DL/T 849.6-2004
随着CVT（电容式电压互感器）技术的不断成熟， CVT得到不断的推广。采用传统的方式对CVT进行校验，由于CVT的主电容量比较大，一般为0.005~0.02uF，因此，对试验电源的容量要求就很高，通常为几十上百千伏安甚至几百千伏安，现场往往难得找到这么大容量的电源，而且，这么大容量的电源重量为好几百公斤甚至好几吨，不易于搬动，不易于现场试验。因此，我们西高华电采用了串联谐振的原理，采用了无极手动调感的技术，研发出了新一代的CVT校验专用工频串联谐振升压装置，使得所需电源、试验设备体积和重量几十倍的下降，方便的满足35kV、66kV、110kV、220kV、330kV、500kV电压等级各类型CVT校验的升压要求。 XGTF 系列装置采用多节电抗器串联的方式，体积小、重量轻，接线操作简单，是电力计量、高压测试专业人员理想的新型换代产品。
根据用户要求，电抗器分为固定电抗器和可调电抗器两种方式。
