TY - JOUR AU - Kairys, A. AU - Kostrauskas, P. PY - 2004/09/21 Y2 - 2024/03/29 TI - The Ways of Making the Power Transformer’s Transformation Coefficient More Precise JF - Elektronika ir Elektrotechnika JA - ELEKTRON ELEKTROTECH VL - 55 IS - 6 SE - DO - UR - https://eejournal.ktu.lt/index.php/elt/article/view/10879 SP - AB - <p>Presented the method of determination transformation coefficient of power transformer, when known distance between primary and secondary windings. Given dependency between magnetic fluxes and no-load voltages. Transformation coefficients are express as functions of magnetic fluxes (main and leakage) and no-load voltages. Formulas are received with estimation of magnetic leakage fluxes for calculation of the number turn windings of multi-wound transformer under given turn ratio with inaccuracy not exceeding ±0,5%. Presented physical model of multi-wound power transformer, which allow calculate a number of turns of secondary windings for defined transformation coefficient. The Results of the work can be used when designing power multi-wound transformer with specifically exact transformation coefficient.
