摘　　要：文章介绍了一种简便的继电保护测试仪暂态特性参数检测方法,该方法在高速数据采集系统基础上,采用数字插值分析手段,大幅提高了信号处理的精度,并结合FFT滤波平滑算法去除波形干扰,从而准确、方便地完成继电保护测试仪暂态特性参数检测。The paper briefly describes the detection method of transient behaviour for relay protection tester. On the basis of the high speed data acquisition, this method uses mathematical interpolation analysis tools, and significantly improves the accuracy of signal processing, combined with FFT filter smoothing algorithm to remove the wave interfer- ence, to accurately and easily complete the detection of transient behaviour for relay protection tester.
