Oscillographic Fault Recording

5.6.1

Mode of operation

During a fault event, the instantaneous measured values are stored at intervals of 1
ms (f

N

=

50 Hz) and 833 µs (f

N

=

60 Hz) in a buffer of the central unit.

A fault record is initiated by

•

a trip from an internal protection function,

•

a binary input with the annunciation "

>Trig.Wave.Cap.

" marshalled to it, or

•

a test fault record request entered via

−

DIGSI or

−

the central unit front panel.

Oscillographic fault recording covers the differential and restraint currents of each
phase for all bus zones and the check zone.

After initiation of the fault recording, the data are stored in a range from max. 500 ms
before the TRIP command to max. 500 ms after it. The period for the fault recording
is max. 5s. Up to 8 fault records can be viewed in the central unit. New fault records
are always entered in the fault record data buffer. As soon as the fault record data buff-
er is full, new fault data overwrite the older data. Fault recording is initiated, for in-
stance, by a busbar short-circuit, by binary ínput 2 marshalled to
("

>Trig.Wave.Cap.

FNo. 4/CU

) or by the parameter

ReleasFltRecBuf.

(

8300/CU

).

The data can be read out to a PC and evaluated by the DIGSI communication soft-
ware.

The fault record data buffer SIPROTEC 7SS52 V4 is protected against data loss in
case of power failures.

Note

A description of the bay unit's fault recording function is provided in Chapter 5.13,
page 182.
Reading out of oscillographic fault recording data is described in Chapter 6.2.3, page
221.
