4. Compare the harmonic amplitude level value with the set warning limit value.
5. Continue to inject the same level of harmonics level until the THDALM signal appears and
note down the time from THDWRN set to THDALM set.
6. Compare the noted time value with the set time limit value of alarm.

3. Slowly increase the harmonic amplitude until the 2NDHDWRN signal appears.
4. Compare the harmonic amplitude level value with the set warning limit value.
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.

11.13.1

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.

ETPMMTR
Prepare the IED for verification of settings as outlined in section "Overview " and
section "Preparing for test" in this chapter.
11.13.2.1

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
