A new approbation of the previously presented method for recognizing a failed branch in one-sided observation of a power transmission line has been carried out. A real line of short length with four branches, two of which are almost identical, is con

The division of short-circuit (SC) current into preceding and fault components has been known and widely used for a long time. The fault component carries information about the fault location, because it is created by the current flowing there. The p

Two problems of structural analysis of electrical quantities are considered: the suppression of spectral components and selection of orthogonal harmonic components of unknown frequency. Each procedure starts with a minimum possible number of counts o

Algorithms based on differential protection for comparing the instantaneous values of two currents, and the segmentation and recovery of a distorted current, are considered from unified positions. A key position is localization of that subset of obse

Recognition of turn-to-turn faults in the series winding of an autotransformer is studied. At one time the conclusion had been drawn regarding a low, even zero, sensitivity of the transformer differential relay protection (TDP) series and distance re

This article aims to bring the provisions of multiresolution analysis closer to digital processing of a short circuit in the electrical network. A kind of “edge effect” arising in processing more than two wavelet coefficients, when the window of
