Section 11
Testing functionality by secondary injection
Verification of function monitoring outputs
1.
Connect the test set for injection of three-phase currents and three-phase voltage to the appropriate
current and voltage terminals of the IED.
2.
Ensure the TRIP, TRLx* output signals from PHPIOC function block connected to TRINALL,
TRINLx* input signals of SMPPTRC function block. Also, create the TRIP output signal from
SMPPTRC function block to TRIGFLTUI input signal of FLTMMXU function block.
3.
Initially inject three-phase analog magnitude and phase angle values in current and voltage
channels in such a way that PHPIOC function does not respond for such an input value.
4.
Then by ramping up the single-phase or three-phase input currents, managed to get the TRIGFLTUI
input signal as TRUE.
5.
Check that the FLTILxMAG*, FLTILxANG*, FLTINMAG, FLTINANG, FLTULxMAG*, FLTULxANG*,
FLTUNMAG, FLTUNANG, IMAXMAG, ILxMAXPK* and ILxMAX* output signals reads the
corresponding values after PostTrig setting.
6.
Check the TRIGDUR output which shows the TRIGFLTUI input signal active duration in ms.
7.
Check the TRIGTIME output which shows the IED current date and time of the instant when
TRIGFLTUI input signal become active.
* (where Lx = Phase L1, L2 and L3)

Completing the test
Continue to test another function or end the test by changing the Test mode setting to Off. Restore
connections and settings to their original values, if they were changed for testing purposes.

Verifying the signals and settings
The Fault locator function LMBRFLO depends on other functions to work properly, that is, phase
selection information from distance protection function and analog information supplied by the trip value
recorder function. Check that proper binary initiate (pickup or tripping) and phase selection signals are
connected and voltage and current signals are configured (parameter settings).
