Abstract

Partial discharge measurement at power transformers are often superposed with by disturbances and beset with problems caused by processing of huge amount of data. To reduce noise and data an effective method using orthogonal transformations was employed. On synthetically generated signals, choice of a suitable orthogonal transformation concentrates the signal energy in a small area of the observed spectrum. One of the methods used for noise reduction limits the disturbances by a transformation to a few spectral component. Another method limits the PD parts of the measured signal to a few spectral components and gives the user the possibility of effective data reduction. Discrete cosine transformation and discrete Hartley transformation are presented and compared with the DFT and FFT.
