摘要
为了对阻抗继电器的动态阻抗特性进行测试 ,文章分析比较了 3种用于继电器测试的测试模型 .根据系统侧阻抗恒定的模型 ,利用微机型继电保护测试装置模拟正、反两个方向上的短路故障成功地对LZ - 16型相间阻抗继电器的动态特性进行了测试 .
In order to test the dynamic characteristics of distance relays,three models for test are analysed and compared. By means of a protective relay test set,using constant source impedance model,the dynamic characteristic of a LZ-16 relay for both a forward and reverse fault is tested with success.
