摘要
用自制的高频电流传感器对３种典型电流波：阶跃波、冲激波、正弦稳态波作用时的输出响应进行了理论分析和实际测试．理论与实测结果表明，对阶跃波和冲激波，传感器的输出为衰减振荡波；对正弦稳态波，当输入正弦波频率与传感器自振频率相等时，传感器的输出最大．高频电流传感器作为检测阻抗。
High frequency current sensor (HFCS) is an important part in on line measurement of partial discharge in a transformer.This paper made theoretical analysis and gave the test results of the output response to three typical current waves namely step jump wave,shock wave and steady sine wave input respectively to a same HFCS,made by ourselves.There is only a very small error of the calculation between theoretical and experimental results.
