Schweitzer Engineering Laboratories SEL-311C - Retrieving Full-Length Standard Event Reports

12.6
SEL-311C Relay Instruction Manual Date Code 20060320
Standard Event Reports and SER
Standard 15/30/60/180-Cycle Event Reports
Targets
The relay reports the targets at the rising edge of TRIP. The targets include the
following:
➤ ZONE/LEVEL 1–4
➤ TIME
➤ COMM
➤ SOTF
➤ 51
If there is no rising edge of TRIP in the report, the Targets field is blank. See
Front-Panel Target LEDs on page 5.31.
Currents and Voltages
Pre-fault current and voltage magnitudes and phase angles are selected from
the first cycle of the event report. Fault currents and voltages use the same data
as the fault locator. If the fault locator does not operate, the fault data are
sampled one and one-quarter cycles after the event report is triggered.

Event Reports
The latest event reports are stored in nonvolatile memory. Each event report
includes five sections:
➤ Current, voltage, station battery, and V1Mem
➤ Protection and control elements, contact outputs, and
optoisolated inputs
➤ Communications and MIRRORED BITS elements
➤ Event summary
➤ Group, SELOGIC control equations, and global settings
Use the EVE command to retrieve the reports. There are several options to
customize the report format. The general command format is:
EVE [n Sx Ly L R A D C M P]
where:
n Event number (1 to number of events stored),
corresponding to the number displayed in the HIS report.
Defaults to 1 if not listed, where 1 is the most recent
event.
Sx Display x samples per cycle (4 or 16); defaults to 4 if not
listed.
Ly Display y cycles of data (1 to LER). Defaults to LER
value if not listed. Unfiltered reports (R parameter)
display an extra cycle of data.
L Display 16 samples per cycle; same as the S16 parameter.
R Specifies the unfiltered (raw) event report. Defaults to 16
samples per cycle unless overridden with the Sx
parameter.
A Specifies that only the analog section of the event is
displayed (current, voltage, station battery, polarizing
voltage).
D Specifies that only the digital section (protection and
control elements) of the event is displayed.
C Display the report in Compressed ASCII format.
