1.
Connect the test set for three-phase current injection to the appropriate IED
terminals.
2.
Inject a symmetrical three-phase current larger than the set value I<.
3.
Decrease the injected current in phase L1 and note the operated value (start
value) of the studied step of the function.
4.
Increase the current slowly and note the reset value.
5.
Connect a trip output contact to a timer.
6.
Decrease the injected current step-wise to 50% of the operate level and check
the time delay.
7.
Check that all trip and start contacts operate according to the configuration
(signal matrices).
8.
Finally check that start and trip information is stored in the event memory.
9.
Repeat steps 2 – 7 for phases L2 and L3.
Completing the test
Continue to test another function or end the test by changing the
TESTMODE
setting to
Off
. Restore connections and settings to their original values, if they were
changed for testing purposes.

Prepare the IED for verification of settings outlined in Section
This function is functionality tested together with other protection functions (line
differential protection, earth-fault overcurrent protection, and so on) within the
IED. It is recommended that the function is tested together with the autorecloser
function, when built into the IED or when a separate external unit is used for
reclosing purposes.

1.
Check that
AutoLock
and
TripLockout
are both set to
Off
.
2.
Initiate a three-phase fault.
An adequate time interval between the faults should be considered, to
overcome a reclaim time caused by the possible activation of the autorecloser
function SMBRREC. The function must issue a three-phase trip in all cases
when trip is initiated by any protection or some other built-in or external
function. The following functional output signals must always appear
simultaneously: TRIP, TRL1, TRL2, TRL3 and TR3P.
