摘要

介绍了离散小波变换在局部放电测量中的应用。用11千伏电缆的现场实测数据对该算法进行了验证。在进行在线测量时，由于测量结果受到内部低频干扰的影响，导致测量结果不准确。结果表明，使用该技术可以精确定位局部放电。

Robust partial discharge measurement in MV cable networks using discrete wavelet transforms

This paper describes the application of discrete wavelet transforms to partial discharge (PD) measurements. Real field data measured from an 11 kV cable online has been used to test the algorithm. When taking measurements online, inaccuracy occurs when the measurements are affected by internal low frequency disturbances. Results demonstrate that the use of this technique leads to accurate location of partial discharge.
