Abstract
Transformatori su važan dio elektroenergetske mreže koji transformiraju snagu s jedne naponske razine na drugu. Transformator radi na principu magnetske indukcije. Osnovna fizikalna načela koja opisuju rad transformatora su Faradayev zakon magnetske indukcije i Ampèreov kružni zakon. Na primarnoj i sekundarnoj strani postoje namoti koji mogu biti spojeni u zvijezdu, trokut ili u razlomljenu zvijezdu. Za računanje jednopolne i tropolne struje kratkog spoja je bitno znati iznose direktne, inverzne i nulte reaktancije. Za 3 dvonamotna i jedan tronamotni transformator koji su obrađeni, diretkna i inverzna reaktancija su jednake, dok se nulta razlikuje ovisno o grupi spoja, dok satni broj ne utječe na iznose reaktancija.
Abstract (english)
Transformers are an important part of the power grid that transform power from one voltage level to another. The transformer works on the principle of magnetic induction. The basic physical principles that describe the operation of transformers are Faraday's law of magnetic induction and Ampère's circular law. On the primary and secondary sides there are windings that can be connected in a star, triangle or in a broken star. To calculate single-phase and three-phase short-circuit current, it is important to know the amounts of direct, inverse and zero reactance. For the 3 two-winding and one three-winding transformers processed, the direct and inverse reactances are the same, while the zero differs depending on the connection group, while the clock hour number does not affect the reactance amounts.
