CEVENT C
OMMAND
– SEL-351P
Display event report in compressed ASCII format by sending:
CEV [n Sx Ly L R C] (parameters in [ ] are optional)
where: n event number (1 - 30) if LER = 15, (1 - 15) if LER = 30, defaults to 1
Sx x samples per cycle (4 or 16); defaults to 4
If Sx parameter is present, it overrides the L parameter
Ly y cycles event report length (1 - LER) for filtered event reports,
(1 - LER+1) for raw event reports, defaults to 15 if not specified
L 16 samples per cycle; overridden by the Sx parameter, if present
R specifies raw (unfiltered) data; defaults to 16 samples per cycle unless
overridden by the Sx parameter. Defaults to 16 cycles in length unless
overridden with the Ly parameter.
C specifies 16 samples per cycle, 15 cycle length
The relay responds to the CEV command with the nth event report as shown below. Items in
italics will be replaced with the actual relay data.

where: xxxx are the data values corresponding to the line labels.
yyyy is the 4-byte hex ASCII representation of the checksum.
FREQ is the power system frequency at the trigger instant.
SAM/CYC_A is the number of analog data samples per cycle (4 or 16).
SAM/CYC_D is the number of digital data samples per cycle (4 or 16).
NUM_OF_CYC is the number of cycles of data in the event report.
EVENT is the event type.
LOCATION is the fault location.
SHOT is the recloser shot counter.
TARGETS are the front-panel tripping targets.
IA, IB, IC, IN, IG, 3I2 is the fault current.
TRIG refers to the trigger record.
