电流互感器二次阻抗的现场测试计算

On-site Test and Calculation of Secondary Impedance of Current Transformer

介绍了电流互感器实际二次阻抗的现场测试、计算方法。该方法所需设备少、重量轻,操作简便;不需新增专用设备,不需三相电源;通用性强,适用于各种形式接线的电流互感器。

The method of on - site test and calculation for actual secondary impedance of current transformer have been introduced. The method needs small and light equipment and is easy to opomte. There needs no new special equipment and three- phase power supply. It has strong universality and is suitable for current transformer with various wire connection.
