Testing functionality by secondary injection
5. Continue to inject the same level of harmonics level until the 2NDHDALM signal appears and note
down the time from 2NDHDWRN signal set to 2NDHDALM signal set.
6. Compare the noted time value with the set time limit value of alarm.
7.
Repeat Steps
10.10.9.2 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.

10.10.11 Fault current and voltage monitoring function FLTMMXU
Prepare the IED for verification of settings as outlined in section
for test" in this chapter.
10.10.11.1 Verifying the settings
Common test equipment can be used to determine the injection of current and voltage and time
measurement.
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.
