SEL-311B Instruction Manual
Group
Active settings group at trigger time.
Targets
The relay reports the targets at the rising edge of TRIP. The targets include: ZONE/LEVEL
1–3; TIME; DT; SOTF; and 51. If there is no rising edge of TRIP in the report, the Targets field
is blank. See
Front-Panel Target LEDs
in
Section 5: Trip and Target Logic
.
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 is sampled one and one-quarter cycles after the event
report is triggered.
Retrieving Full-Length Standard Event Reports
The latest event reports are stored in nonvolatile memory. Each event report includes five
sections:
·
Current, voltage, station battery, and V1Mem
·
Protection elements, contact outputs, and optoisolated inputs
·
M
IRRORED
B
ITS
and SEL
OGIC
control equation elements
·
Event summary
·
Group, SEL
OGIC
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
S
x
L
y
L R A D C M]
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.
S
x
Display
x
samples per cycle (4 or 16); defaults to 4 if not listed.
L
y
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 S
x
parameter.
