“…When a metallic grounding fault occurs on the line, the voltage of the fault point is zero, i.e., U ̇(x) = 0. Using (11), a relation between the measured impedance and the fault distance is obtained in (12). The measured impedance accounts for the distributed capacitance of the transmission line.…”

“…Z m (ωx) = Z c sinh(γx)/ cosh(γx) (12) where ω is the power frequency. When the transmission line is equivalent to that in the R-L model, the unit impedance of the line is r 1 + jωl 1 .…”

“…Alguns trabalhos investigam o impacto da saturação do TC na proteção de distância (MOONEY, 2008;WANNOUS;TOMAN, 2016). A referência (ZHENG et al, 2021) propõe uma abordagem para a proteção de distância na configuração disjuntor e meio, que combina critérios de bloqueio e desbloqueio da proteção de distância garantindo sua confiabilidade para faltas diretas e saturação de TC induzida por faltas reversas.…”
