Certas faltas fazem com que as correntes decaiam com o tempo fazendo com que a corrente falta no período de regime (“steady-state”), após alguns ciclos, possa ser menor que a corrente nominal do sistema (menor do que 1 pu).

Antes que o relé opere, a corrente já se tornou consideravelmente menor do que o pickup do relé.
