DORRBERCKER DRAKE, Santiago Alfredo; BENITEZ GONZALEZ, Ivón Oristela; TORRES MEDINA, William José    URQUIOLA LESCAILLE, Alejandro. Denoising of partial discharge q,φ,n patterns. []. , 35, 3, pp. 202-212. ISSN 1815-5901.

The measurement of partial (PD) discharges is sustained in the detection and filtration of current pulses which appear in a band of frequency that include from the kilohertz until the gigahertzios, for such a reason the detectors of partial (PDD) discharges they possess systems for the separation of this current pulses. However, PDD also allows the step of other signals of high frequency, denominated noises, that mix with the pulses of PD and they affect measurement, interpretation and characterization of PD. To attenuate that effect, different techniques have been developed to separate the noises so much associated to the signs like the existent ones in the q,φ,n patterns. In this paper are presented the results obtained in the noise reduction of the noises associated to the thyristor's commutation and the sporadic noises, in the q,φ,n patterns by means of the technical of digital images processing
