Resolution
Compressed ASCII
Event Reports
The SEL-351A provides Compressed ASCII event reports to facilitate event
report storage and display. The SEL-2032, SEL-2030, and the SEL-2020
Communications Processors and the SEL-5601 Analytic Assistant software
take advantage of the Compressed ASCII format. Use the EVE C command
or CEVENT command to display Compressed ASCII event reports. See the
CEVENT Command—SEL-351A on page E.7 for further information.
Filtered and
Unfiltered Event
Reports
The SEL-351A samples the basic power system measurands (ac voltage, ac
current, station battery, and optoisolated inputs) 16 times per power system
cycle. The relay filters the measurands to remove transient signals. The relay
operates on the filtered values and reports them in the event report.
To view the raw inputs to the relay, select the unfiltered event report (e.g.,
EVE R). Use the unfiltered event reports to observe:
NOTE: VS is not available in the
SEL-351A-1.
➤ Power system harmonics on channels IA, IB, IC, IN, VA, VB,
VC, VS
➤ Decaying dc offset during fault conditions on IA, IB, IC
NOTE: Compressed ASCII Event
Reports contain all of the Relay Word
bits. Regular, uncompressed event
reports only contain a subset of the
Relay Word bits.
