Communications Protocols
Use the BRE R command to reset the breaker monitor:
See Breaker Monitor on page 5.19 for further details on the breaker monitor.
CEV Command
The SEL-751 provides Compressed ASCII event reports to facilitate event
report storage and display. SEL communications processors and the
ACSELERATOR Analytic Assistant SEL-5601 Software take advantage of the
Compressed ASCII format. Use the CHIS command to display Compressed
ASCII event history information. Use the CSUM command to display
Compressed ASCII event summary information. Use the CEVENT (CEV)
command to display Compressed ASCII event reports. See Tab le C.2 for
further information. Compressed ASCII Event Reports contain all of the
Relay Word bits. The CEV R command gives the raw Compressed ASCII
event report. Additionally, the compressed event report has the arc-flash
detector light measurements.
CEV HIF (High-Impedance Fault) Command
The SEL-751 provides Compressed ASCII event reports to facilitate event
report storage and display. SEL communications processors and the
ACSELERATOR Analytic Assistant SEL-5601 Software take advantage of the
Compressed ASCII format. Use the CEV HIF command to display
Compressed ASCII HIF event reports.
The relay generates compressed event reports to display analog data, and the
state of related Relay Word bits from the odd and non-harmonic HIF fault
detection algorithm and load reduction. The relay provides user-
programmable event report triggering conditions. An event report is triggered
