fault summary report, it freezes a 4 cycle pre-fault buffer. If the fault is not cleared within that time, the
fault reporting function records a second oscillographic record. This second record captures the end of
the fault. Oscillographic records are stored in volatile memory. As additional faults are recorded, the
oldest records are overwritten. The relay has 240 cycles of memory. The SG-OSC setting sets the
number of partitions and the length of the record is a function of the number of records. See Table 6-14.
If a second oscillographic record is required, the fault recording function will continue to record sample
data in the second record with no gap. During this time, a 5-cycle buffer is being filled. If the fault is
cleared within 5 cycles of the start of the second record, the record is terminated after it finished. If the
fault does not clear in that period, the fault reporting function continues to save 5 cycles of sample data in
its buffer until the fault is cleared. At that point, it freezes the 5-cycle buffer, providing 5 cycles of end of
fault data.

Oscillographic Records Settings
The oscillographic records settings can be programmed through BESTCOMS. To select the number of
records, select Reporting and Alarms from the Screens pull-down menu. Select the Fault Recording tab
and click the Select box in the Oscillographic Records pane. Make your selection as shown in Figure
6-17, Oscillographic Records Selector. Select Done once the setting has been made.

The oscillographic records settings can also be made using the SG-OSC (settings general, oscillography)
ASCII command. See Table 6-15 for possible settings.
