Trip Log (Fault Messages)
Retrieved
messages
The messages for the last eight network faults can be retrieved. The definition of a net-
work fault is such that the time period from fault detection up to final clearing of the
disturbance is considered to be one network fault. If auto-reclosing occurs, then the
network fault ends after the last reclosing shot, which means after a successful reclos-
ing or lockout. Therefore the entire clearing process, including all reclosing shots, oc-
cupies only one fault record. Within a network fault, several indications can occur
(from the first pickup of a protective function to the last dropout of a protective func-
tion). These indications are recorded.
In total 600 indications can be recorded. Oldest data are erased for newest data when
the buffer is full.
All available indications are displayed and explained in the Appendix. In a specific
case, of course, only the applicable messages appear on the display.

If no messages are present for a fault record, then enterance is denied and “
/LVW
(PSW\
” is displayed.
The messages within a fault record are listed in chronological order and numbered,
from the oldest to the newest.
The inception of a fault is identified with the date and time in hours, minutes, and sec-
onds (resolution to ms). See the example in Figure 7-6.
The individual messages that are associated with the fault are given a relative time. At
least one complete individual message always appears in the display.
