Defining and computing equivalent inductances of gapped iron core reactors

The paper revisits the fundamental definitions and explores computational alternatives of equivalent inductances of gapped iron core reactors. Unlike in a transformer, the physical meaning of component inductances of a reactor is subject to uncertainty and open to different interpretations, leading to various equivalent circuits. It is argued that a definition based on flux distribution may not be reliable and calculations based on energy or co-energy are thus preferable. Streszczenie. W artykule omowiono podstawowe definicje i metody obliczania indukcyjności zastepczych dlawikow ze szczelinami powietrznymi. Uzywane są rozne schematy zastepcze zalezne od interpretacji fizycznej. Zasugerowano definicje oparte na energii i koenergii systemu zamiast rozkladu strumienia magnetycznego. (Definicje i obliczanie indukcyjności zastepczych dlawikow ze szczelinami powietrznymi)
