小波变换在电缆故障定位中的应用

The Application of Wavelet Transform in Cable Fault Location

对电缆故障定位中常用的相关分析方法进行了模拟试验和误差分析 ,介绍了在数字信号处理领域应用广泛的小波变换的基本算法 ,引入基于离散小波变换的滤波器对测试数据进行处理 ,自行研制的定位仪样机试验结果表明

Simulation experiment and error analysis of correlation analysis method used in cable fault location is performed and the wavelet transform arithmetic method widely used in DSP is introduced. The experiment data is processed by the filter based on discrete wavelet transformation. The test results of self developed locator indicate that high fault location precision can be gained by use of wavelet transform arithmetic method.
