Inrush Restraint

During the voltage restoration on the MV overhead line, the device blocks the detection of faults due to the
transformer magnetization within the configured inrush-restraint time.
The inrush-restraint time can be configured as Disabled, 3 s, 30 s, and 60 s. The inrush-restraint time is
initiated only after a voltage is detected in SICAM FSI.
If the inrush-restraint time is set as Disabled, it is internally considered as 1 s.
