Instruction Manual
Testing and Troubleshooting
Overview
Device testing is typically divided into two categories:
➤ Tests performed at the time the device is installed or
commissioned.
➤ Tests performed periodically once the device is in service.
This section provides information on both types of testing for the SEL-2414
Transformer Monitor. Because the SEL-2414 is equipped with extensive self-
tests, traditional periodic test procedures may be eliminated or greatly reduced.
Should a problem arise during either commissioning or periodic tests, the section
on Troubleshooting on page 10.13 provides a guide to isolating and correcting
the problem.
Functional Testing
Because the SEL-2414 is equipped with extensive self-tests, the most effective
maintenance task is to monitor the front-panel messages after a self-test failure.
In addition, each device event report generated by a fault should be reviewed.
Such reviews frequently reveal problems with equipment external to the device,
such as instrument transformers and control wiring.
The SEL-2414 does not require specific routine tests, but your operation stan-
dards may require some degree of periodic device verification. If you need or
want to perform periodic device verification, the following checks are recom-
mended.
Device Status Verification
Use the front-panel STATUS or serial port STATUS command to verify that the
device self-tests have not detected any WARN or FAIL conditions.
Input Verification
Using the front-panel MAIN > TARGETS > ROW 48 function, check the
control input status in the device. As you apply rated voltage to each input, the
position in Row 48 corresponding to that input should change from zero (0) to
one (1).
