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 TDDALM signal appears and note
down the time from TDDWRN set to TDDALM set.
6. Compare the noted time value with the set time limit value of alarm.

1. Supply the IED with current at rated value.
2.
Apply 2

order harmonic along with injected current signal.
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.

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.
