Communications Protocols
Use the TIME hh:mm and TIME hh:mm:ss commands to set the internal
clock time. The value hh is for hours from 0–23; the value mm is for minutes
from 0–59; the value ss is for seconds from 0–59. If you enter a valid time, the
relay updates and saves the time in the nonvolatile clock, and displays the time
you just entered. If you enter an invalid time, the SEL-751 responds with
Invalid Time.
TRIGGER Command (Trigger Event Report)
Use the TRI command (see Table 7.53) to trigger the SEL-751 to record data
for high-resolution oscillography and event reports.
When you issue the TRI command, the SEL-751 responds with
Triggered.
If the event did not trigger within one second, the relay responds with
Did
not trigger
. See Section 10: Analyzing Events for further details on event
reports.
TRIGGER HIF Command
Use the TRI HIF command (see Table 7.54) to trigger the SEL-751 to record
data for high-impedance fault event reports. This command is only available
when the relay supports HIF detection and EHIF is not set to N. When you
issue the TRI HIF command, the relay responds,
triggered. If the event did
not trigger within 1 second, the relay responds,
did not trigger.
VEC Command (Show Diagnostic Information)
Issue the VEC command under the direction of SEL. The information
contained in a vector report is formatted for SEL in-house use only. Your SEL
application engineer or the factory may request a VEC command capture to
help diagnose a relay or system problem.
Language Support
All of the ASCII commands can be displayed in multiple languages (English
or Spanish). When you set the port setting LANG (see Table 4.83) to either
ENGLISH or SPANISH, the SEL-751 displays the ASCII commands in the
corresponding language. See the SEL-751 Relay Command Summary for a list
of the commands.
