6.2.3 Reading Out Fault Data
from the PC
with DIGSI
Figure 6-10 Window of the operational measured values DIGSI − Example
The fault data of the bay units are stored in the bay units and the fault data of the cen-
tral unit are stored in the central unit. To retrieve and record the fault data from these
locations, you need one of the SIGRA programs in addition to DIGSI (optionally avail-
able to DIGSI) or the Comtrade Viewer (included in DIGSI).
As a prerequisite for recording the fault data, the corresponding parameters such as
the length, the pre-trigger time and the post-fault time of the fault recording must be
set according to the Chapters 5.6, page 158 and 5.13, page 179.
To read out fault data centrally (PC linked to central unit) proceed as follows:
Click Oscillographic Records in the navigation window. The subdirectory of the
Oscillographic Records now shows the item Oscillographic Fault Records in the
navigation window (Figure 6-1, page 207). The list view in the right section of the
window gives an overview of all available fault records. The fault records are dis-
played with the network fault number, a fault record number and date and time. The
numbers for network fault and fault record are always identical for 7SS52 V4 and
for each fault in the power system they are numbered starting from 1 upwards.
