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)
10.10.11.2 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.
10.11 Metering
10.11.1 Pulse-counter logic PCFCNT
The test of the Pulse-counter logic function PCFCNT requires the Parameter Setting tool in PCM600 or
an appropriate connection to the local HMI with the necessary functionality. A known number of pulses
with different frequencies are connected to the pulse counter input. The test should be performed with
settings Operation = Enable or Operation = Disable and the function blocked or unblocked. The pulse
counter value is then checked in PCM600 or on the local HMI.
10.11.2 Function for energy calculation and demand handling ETPMMTR
Prepare the IED for verification of settings as outlined in section "Overview " and section "Preparing for
test" in this chapter.
10.11.2.1 Verifying the settings
Common test equipment can be used to determine the injection of current and voltage and time
measurement.
Verification of EAFACC & ERFACC output
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 instantaneous values of active and reactive power from CVMMXN function block are
connected to ETPMMTR function block active and reactive power inputs.
3. Enable the EnaAcc setting and set tEnergy as 1 minute.
4. Activate the STARTACC input and supply the IED with three-phase currents and voltages at their
rated value.
5. Check that the ACCINPRG signal appears continuously.
6. Note the EAFACC and ERFACCvalue after 1 minute and compare it with calculated energy value.
7. Similarly check after each 1 minute whether the calculated integrated energy value and EAFACC and
ERFACC outputs are matching.
8. After some time (multiple of minute) remove the current and voltage input from CVMMXN function
block.
9. Check the EAFACC and ERFACC output in the next 1 minute cycle for the retaining the same value.
