Completing the test

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

Metering

12.13.1

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
function blocked or unblocked. The pulse counter value is then checked in PCM600 or on the
local HMI.

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.
12.13.2.1

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
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.
10. Activate STOPACC input after some time and supply the IED with same current and
voltage.
11. Check that the ACCINPRG signal disappears immediately and EAFACC and ERFACC outputs
also stop updating.
12. Similarly the testing can be done for EAFACC and ERFACC outputs by changing the power
inputs directions through direction settings.
Verification of MAXPAFD & MAXPRFD outputs
