“…• The worst CT saturation is produced by the dc component of the primary current. During this dc saturation period, the second-ary current may contain dc offset and odd and even harmonics [7], [19]. When the dc offset dies out, the CT has only ac saturation, characterized by the presence of odd harmonics in the secondary current [6], [7], [20].…”

“…When the performance of a power transformer protection system and its adjustment are considered, it is necessary to take into account current transformer (CT) saturation and its effect on protective relays [22][23][24][25].…”

“…O trabalho apresentado pelos autores Wentz e Sonnemann (1940) apresenta uma análise sobre a aplicação de TCs em conjunto com relés de proteção de alta velocidade, cujo enfoque principal é o aparecimento da componente de Corrente Contínua (CC) nas correntes transitórias. O problema enfatizado no texto é a escolha do esquema de proteção diferencial frente a eficácia dos TCs existentes, uma vez que o desempenho destes equipamentos estava distante da perfeição.…”
