Inventors include Alberto, Diego; El Khoury, Diana; and Durand, Maxime Ep.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: Abstract The invention relates to a method for detecting partial discharges in an insulator (2) of a medium-voltage electrical conductor (1), comprising: (i) acquiring a set (E) of samples of an electrical signal (S) representative of a partial discharge, (ii) for each sample, determining the phase (P) of the alternating voltage, (iii) establishing a matrix (M) of the number of samples for a set of signal amplitude ranges of the signal (S) and a set of ranges of phase values (P), (iv) determining in the established matrix (M) a noisy zone (B), according to a condition based on: - a statistical quantity representative of a number of values associated with a range of amplitude of the signal (S), - a statistical quantity representative of a variability of the signal (S), (v) replacing each element of the noisy zone (B) by a mathematical combination of elements outside the noisy zone (B) to form a corrected matrix (M-c), (vi) detecting the presence of partial discharges from the corrected matrix (M-c).
