产品介绍：
用变比电桥测量变压器的变比，操作过程繁琐，测量范围狭窄, no longer suitable. Our company developed a new generation transformer ratio group tester. Compact, lightweight, precise, stable好。它采用了大屏幕汉字显示、菜单操作，界面友好。变比组别可一次测完。该仪器是电力工业部门的理想测试仪器。
Product Features：
◆ Auto winding group measurement.
◆ Auto group change.
◆ Auto phase sequence switch.
◆ Auto range switch.
◆ Auto calibration.
◆ Auto error calculation after standard ratio input.
◆ Auto voltage cutoff after measurement.
◆ Auto save, history viewable.
◆ Single input for OLTC transformers.
