MiCOM P632
Acquisition of the Fault Currents
graphics/symbols/xh_bw.gif graphics/symbols/xh_fw.gif

The P632 stores the fault currents data determined at the acquisition time.

The following fault currents are stored:

▪

The maximum phase currents for each end of the transformer

▪

The residual current calculated from the phase currents

▪

The current measured by the P632 at transformer -Tx4 (x: 1, 2 or 3) The fault currents are displayed as per-unit quantities referred to Inom.
