The paper presents the results of the correct online evaluation of the current technical condition of the electrical equipment in high voltage substations owned and operated by Romanian Power Grid Company — CNTEE Transelectrica SA, using intelligent monitoring systems. During 2010–2013, CNTEE Transelectrica implemented a Smart Grid pilot project consisting of the on-line monitoring and diagnosis of...
The paper presents the results of the correct on-line evaluation of the current technical condition of the electrical equipment in high voltage substations owned and operated by Romanian Power Grid Company — CNTEE Transelectrica SA, using intelligent monitoring systems. The paper describes parts of the intelligent systems dedicated to on-line monitoring of all primary equipment used in the 400/110...
The paper proposes an enhanced wavelet-based feature extraction technique to classify transformer inrush currents (TIC) and transformer internal faults (TIF). The proposed tool utilizes the number of wavelet coefficients of local maxima as current signal slides into Kaiser's window. The general pattern of number of coefficients of local maxima at the first three resolutions are used to design a new...
Many studies have been conducted to monitor the degradation of MO arresters. The arresterpsilas leakage current, in particular, the third harmonic component of the resistive leakage current, is known to be directly related to the degree of degradation of the MO arrester. In order to extract the resistive component from the total leakage current, the voltage across the arrester terminals is usually...
