Abstract

Un núcleo de limitador magnético de corriente de falta (10b), que comprende primeros elementos magnéticos (12) y segundos elementos magnéticos (14), estando dispuestos los elementos magnéticos para definir una disposición sustancialmente paralela de elementos magnéticos, incluyendo cada primer elemento magnético (12) un material magnético blando e incluyendo cada segundo elemento magnético (14) un material magnético duro, donde los elementos magnéticos están dispuestos para formar capas primarias alternas de primeros y segundos elementos magnéticos, donde el material magnético blando en un estado saturado tiene una permeabilidad magnética más baja que el material magnético duro y donde el material magnético blando en un estado no saturado tiene una permeabilidad magnética más alta que el material magnético duro.
