Step 6. If you use the Breaker Wear Monitor, type BRE <Enter> to
check the data and see if the relay retained breaker wear data
through the upgrade procedure.
If the relay did not retain these data, use the BRE W n
command to reload the percent contact wear values for each
pole of Circuit Breaker
n ( n = 1, 2, 3, or 4) you recorded in C.
Save Settings and Other Data on page B.6 .
Step 7. Apply current and voltage signals to the relay.
Step 8. Type MET <Enter> and verify that the current and voltage
signals are correct.
Step 9. Use the TRIGGER and EVENT commands to verify that the
magnitudes of the current and voltage signals you applied to
the relay match those displayed in the event report.
If these values do not match, check the relay settings and
wiring.
I. Return the Relay to Service
Step 1. Follow your company procedures for returning a relay to
service.
Step 2. Autoconfigure the SEL communications processor port if you
have an SEL communications processor connected to the relay.
This step reestablishes automatic data collection between the
SEL communications processor and the relay. Failure to
perform this step can result in automatic data collection failure
when cycling communications processor power.
The relay is now ready for your commissioning procedure.
Ethernet Port Firmware Upgrade Instructions
Introduction
Perform the firmware upgrade process in the following sequence:
A. Prepare the Relay
B. Establish an FTP Connection
C. Transfer New Firmware
D. Establish a Telnet Connection
E. Verify Firmware Transfer
A new default CID file might have been included with your firmware upgrade.
Do not load this file into your relay if you have already configured your relay
for IEC 61850 communications. Doing so will overwrite your existing
configuration and disrupt communications with the relay as a result.
Performing a firmware upgrade will not overwrite or corrupt the CID file
already stored in your relay.
NOTE:
SEL-300 series relays with
Ethernet capability support one CID
file, which should be transferred only
if a change in the relay configuration
is required. If an invalid CID file is
transferred, the relay will no longer
have a valid IEC 61850 configuration,
and the protocol will stop operating.
To restart protocol operation, a valid
CID must be transferred to the relay.
