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.
