Abstract
arranjo para reduzir um componente de fluxo unidirecional magnético (¿dc) no núcleo (1) de um transformador, compreendendo: um aparelho de medição (7), que provê um sinal de medição (8) correspondendo ao componente de fluxo unidirecional magnético (¿dc), um enrolamento de compensação (k), que é acoplado magneticamente ao núcleo (1) do transformador, em que o fluxo magnético fluindo no núcleo (1) induz uma voltagem (uk) no enrolamento de compensação, um dispositivo de comutação (5) que é disposto eletricamente em série junto com o enrolamento de compensação (k) em um caminho de corrente (6), um dispositivo de controle, que controla o dispositivo de comutação (5) por meio de um parâmetro de controle (11) de modo que o dispositivo de comutação (5) pode ser comutado para um estado condutivo em um tempo de ativação, em que o tempo de ativação depende do sinal de medição (8) e é síncrono em rede; isto é, síncrono em fase para a voltagem no enrolamento de compensação (k), pelo que uma corrente é suprida ao enrolamento de compensação (k), o efeito do qual é direcionado contra o componente de fluxo unidirecional (¿dc), em que a unidade de comutação (5) é formada por um núcleo magnético (10) e um arranjo de enrolamento (3, 20).
