If not all synchronization conditions are fulfilled, the device continues checking until the monitoring time
6112 T-SYN. DURATION expires. The device then stops itself automatically.
Creating Oscillographic Recordings for Test
General
At the end of commissioning, closing tests may be carried out to assure the stability of the protection during
the dynamic processes. A maximum of information on protection behaviour is supplied by fault recordings.
Prerequisite
Along with the possibility of storing fault recordings via pickup of the protection function, the 7VE61 and
7VE63 also has the capability of capturing the same data when commands are given to the device via the
service program DIGSI, the serial interface, or a binary input. For the latter event,
>Trig.Wave.Cap.
must be
allocated to a binary input. Triggering of the recording then occurs, for example, via the binary input when the
protected object is energised.
Such externally started test fault recordings (i.e., without a protection pickup) are handled by the device as
normal fault recordings, i.e. for each measurement record a fault log is opened with its own number, for
unequivocal allocation. However, these recordings are not displayed in the fault indication buffer, as they are
not fault events.
Triggering Oscillographic Recording
To trigger test measurement recording with DIGSI, click on Test in the left part of the window. Double click
the entry Test Wave Form in the list of the window.

Figure 3-31 Triggering oscillographic recording with DIGSI — Example
A test measurement record is immediately started. During recording, an indication is given in the left part of
the status bar. Bar segments additionally indicate the progress of the procedure.
For display and evaluation of the recording, you require one of the programs SIGRA or ComtradeViewer.
