Abstract

resumo limitador de corrente de curto-circuito, e, método de melhorar a operação de um limitador de corrente de curto-circuito um limitador de corrente de curto-circuito do tipo tendo pelo menos um núcleo orientado magneticamente para a saturação por meio de um campo magnético circundante, e uma bobina ac envolvendo o núcleo, o limitador de corrente de curto-circuito incluindo: um núcleo alongado tendo uma seção cruzada variável ao longo do eixo do núcleo na proximidade da bobina ac, provendo saturação aumentada do núcleo e limitação aumentada da corrente de curto-circuito para um desvio dc inferior. 1/1
