1. Connect the test set for three-phase current injection and three-phase voltage to the
appropriate IED terminals.
2. Inject symmetrical phase voltages equal to the rated voltage.
3. Decrease the injected current in phase A and note the operated value (pickup value) of the
studied step of the function. This current shall have the same phase angle as the injected
phase voltage. The active power for operation is calculated as:
active power).
4. Increase the current slowly and note the reset value.
5. Connect a trip output contact to a timer.
6. Set the injected current to 50% of the operate level in the tested stage. Switch on the current
and check the time delay.
7. Check that all trip and pickup contacts operate according to the configuration (signal
matrices).
8. Finally check that pickup and trip information is stored in the event memory. Repeat steps 3 –
6 for phases B and C.
9. Inject symmetrical phase voltages and phase currents in all three phases, equal to
(rated voltage and current).
10. Increase the phase angle between the injected phase voltages and phase current, and note
the operate value φ. The corresponding power factor is equal to
11. Decrease the phase angle and note the reset value.
12. Set the phase angle of the injected current slightly higher than the operate value. Switch on
the current and check the time delay.
13. Check that all trip and pickup contacts operate according to the configuration (signal
matrices).
14. Finally check that pickup and trip information is stored in the event memory.
Completing the test
continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.

Prepare the IED for verification of settings as outlined in section
"Preparing for test"
1. Set
2. Connect the test set for three-phase current injection and three-phase voltage to the
appropriate IED terminals.
3. Inject symmetrical phase voltages equal to the rated voltage.
4. Decrease the injected voltage in phase A and note the operated value (pickup value) of the
function.
5. Increase the voltage slowly and note the reset value.
6. Connect a trip output contact to a timer.
7. Reduce the injected voltage stepwise to 90% of the operate level, and check the time delay.
8. Check that all trip and pickup contacts operate according to the configuration (signal
matrices).
9. Finally, check that pickup and trip information is stored in the event menu. Repeat steps 4 – 9
for phases B and C.
If voltage compensation will be used, do the following steps:
