关于本仪器
本仪器专用于测试互感器伏安特性、误差曲线、变比、极性、角差比差、直阻、和二次侧回路检查等。实验时仅需设定测试电压/电流值，设备便能够自动升压/升流，并将互感器的伏安特性曲线或变比、极性等测试结果快速显示出来（根据用户选配的机型而不同），支持数据保存和现场打印，不但省去手动调压、人工记录、描曲线等繁琐劳动，还能通过RS232/USB接口实现对仪器的远程控制和数据结果的智能分析，操作简便直观。
注意事项 1、测试前请将仪器可靠接地，测试中严禁触碰所有测试端子。 2、本测试仪为互感器离线测试装置，在对互感器进行各项测试时，请务必将互感器各端子上的连接线断开，互感器的接地线一定要断开。否则会影响检测结果。 3、CT变比极性测试时，应将不检测的二次绕组短接, 否则二次会产生高压。 4、做PT伏安特性测试时，一次绕组的零位端接地，以免产生高压触电。 5、说明书与仪器不符之处，以仪器为准。 2
