Figure 55: Connection of test equipment
1. Connect the test set for three-phase voltage injection to the appropriate IED terminals as
shown in Figure
2. Increase the injected voltage and note the operated value (pickup 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 pickup contacts operate according to the configuration (signal
matrices).
7. 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.
11.11.7.6 Zero sequence overvoltage protection LCZSPTOV (59N)
Prepare the IED for verification of settings as outlined in section
"Preparing for test"
1. Connect the test set for three-phase voltage injection (A, B, C) or residual voltage injection
(N) to the appropriate IED terminals. This depends on how the IED is fed from the VT.
2. Increase the injected zero sequence voltage and note the operated value (pickup 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.
