Compressed ASCII Event Reports
The SEL-387E Relay provides Compressed ASCII event reports to facilitate event report storage
and display. The SEL-2020 or SEL-2030 Communications Processor and the SEL-5601
Analytic Assistant software take advantage of the Compressed ASCII format. Use the
EVE C
command or the
CEVENT
command to display Compressed ASCII event reports. See the
CEVENT
command discussion in
Appendix E: Compressed ASCII Commands
for further
information.
Extracting RMS Phasor Data from Filtered Event Reports
Figure 9.6 and Figure 9.7 look in detail at one cycle of A-phase current (channel IA) from a
typical filtered Event Report. Figure 9.6 shows how the event report ac current column data
relate to the actual sampled waveform and RMS magnitude values. Figure 9.7 shows how the
event report current column data can be converted to phasor RMS values.
