<p>U ovoj doktorskoj tezi razvijen je postupak za ispitivanje uticaja<br />oklopa na merni transformator bez jezgra sa stanovišta<br />linearnosti transformatora i zaštite transformatora od<br />uticaja elektromagnetske smetnje. Formiran je parametarski model<br />oklopa i mernog transformatora bez jezgra. Izvedena su merenja<br />magnetskih karakteristika feromagnetskih materijala, dat je novi<br />analitički model histerezisa i određene su krive magnetisanja i<br />permeabilnosti materijala. Na osnovu numeričkih i<br />eksperimentalnih rezultata, a u skladu sa definisanim<br />kriterijumom, izvršena je analiza kvaliteta oklapanja za<br />razmatrane tipove oklopa.</p> / <p>In this thesis a method for examining the effects of shielding on a coreless<br />measuring transformer from the standpoint of transformer linearity and EM<br />radiation shielding is developed. A parametric model of the shield and the<br />coreless measuring transformer is constructed. Measurements of magnetic<br />properties of ferromagnetic materials were performed; a new analytical model<br />of hysteresis is developed; magnetization curves and permeability of the<br />materials are determined. Based on numerical and experimental results, and<br />using the defined criterion, the analysis of shielding quality of the considered<br />shield types was performed.</p>
