Figure 45: Connection of test equipment
1. Connect the test set for three-phase voltage injection to the appropriate IED
terminals as shown in Figure 45
2. Increase the injected voltage and note the operated value (start value) of the
studied step of the function.
3. Decrease the voltage slowly and note the reset value.
4. Connect a trip output contact to a timer.
5. Set the injected voltage to 110% of the operate level of the tested stage. Switch
on the current and check the time delay.
6. Check that all trip and start contacts operate according to the configuration
(signal matrices).
7. Finally check that start and trip information is stored in the event memory.
Completing the test
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.
