5.4. Fault Reports
A fault report is a record of specific events in the period of time when a fault occurs. On the one
hand, an oscillography record is very extensive information, but only short regarding time for a
significant number of faults. Also, event recording can be filled with general events, which provide
no information of a fault (tables change, local pulsing, etc.) whereby it could be filled with general
information, losing any fault information. Therefore, having a specific events record for the fault
period is of significant help to resolve an incident.
This record has a 20 fault capacity, and each fault can store 80 events. At any moment, the
information of the twenty most recent fault reports is available. Each new fault report generated
is stored on the oldest, is lost, therefore, the information of this one. The fault report is time limited
by means of a fault start and a fault end, and these must be clearly established.
The twenty fault reports are generated and they are registered in no-volatile FRAM memory. From
the HMI, by pressing key “◄”, you will gain access to fault reports. The information displayed is
as follows:
•
Date-time at which the fault started.
•
List of all events occurred in the equipment during the fault
The fault start is the same as that of the oscillography, i.e. an oscillography shall always be
associated to the fault report. The fault end shall depend on whether the recloser is active. If the
recloser is prohibited, when all start ups disappear it is understood that the fault has disappeared
(this includes the circuit breaker fault). With the recloser permitted, the fault end is given by the
final condition of the recloser, regardless of whether it has been successful or it has become
blocked. As a general rule, the following logic shall provide the fault end.
