Acquisition of the Fault Currents
The P631 stores the fault currents data determined at the acquisition time.
The fault currents stored are the maximum phase currents for each end of the
transformer.

Acquisition of the Differential and Restraining Currents
The P631 stores the differential and restraining current data determined at the
acquisition time by the differential protection. Moreover, the values for the
second and fifth harmonics of the differential current are stored.
Differential and restraining currents are stored as per-unit quantities referred to
