13.2.2.2 Recording
SEMOD56528-14 v2
It is of utmost importance to carefully record the test results. Special test sheets
covering the frequency of test, date of test and achieved test values should be used.
IED setting list and protocols from previous tests should be available and all results
should be compared for differences. At component failures, spare equipment is
used and set to the requested value. A note of the exchange is made and the new
measured values are recorded. Test records for several years of testing should be
stored in a common file for a station, or a part of a station, to give a simple
overview of the period of testing and achieved test values. These test records are
valuable when analysis of service disturbances shall be done.
13.2.2.3 Secondary injection
SEMOD56528-17 v2
The periodic maintenance test is done by secondary injection from a portable test
set. Each protection shall be tested according to the secondary injection test
information for the specific protection IED. Only the setting values adopted shall
be checked for each protection function. If the discrepancy between obtained value
and requested set value is too big the setting should be adjusted, the new value
recorded and a note should be made in the test record.
13.2.2.4 Alarm test
SEMOD56528-20 v4
When inserting the test handle the alarm and event signalling is normally blocked.
This is done in the IED by setting the event reporting to Off during the test. This
can be done when the test handle is inserted or the IED is set to test mode from the
local HMI. At the end of the secondary injection test it should be checked that the
event and alarm signalling is correct by activating the events and performing some
selected tests.
13.2.2.5 Self supervision check
SEMOD56528-23 v5
Once secondary testing has been completed, it should be checked that no self-
supervision signals are activated continuously or sporadically. Especially check the
time synchronization system, GPS or other, and communication signals, both
station communication and remote communication.
13.2.2.6 Trip circuit check
SEMOD56528-26 v5
When the protection IED undergoes an operational check, a tripping pulse is
normally obtained on one or more of the output contacts and preferably on the test
switch. The healthy circuit is of utmost importance for the protection operation. If
