Completing The Test; Through Fault Monitoring Ptrsthr; Verifying The Signals And Settings - ABB Relion 670 Series Commissioning Manual

Section 11
Testing functionality by secondary injection
6. Check the time until the warning limit has reached
Monitor the signal WARNING1 until it appears on the corresponding binary output.
7. Compare the measured temperature (HPTMPMAX) with
8. check the time until the warning limit has reached
Monitor the signal WARNING2 until it appears on the corresponding binary output.
9. Compare the measured temperature (HPTMPMAX) with
10. Wait for a time corresponding to
signal. Make sure that the ALARM1 signal appears.
11. Note the time taken for the appearance of ALARM1 signal from the appearance of
WARNING1 signal, and compare it with set value (
12. Wait for a time corresponding to
signal, and make sure that the ALARM2 signal appears.
13. Note the time taken for the appearance of ALARM2 signal from the appearance of
WARNING2 signal, and compare it with set value (
14. Activate the BLKWRN binary input. The WARNING1 and WARNING2 signals should
disappear.
15. Activate the BLKALM binary input. The ALARM1 and ALARM2 signals should disappear.
16. Reset the BLKWRN and BLKALM binary inputs. Once again warning and alarm signals
should appear.
17. Reduce the three-phase currents suddenly to value lower than the rated current and take
note of hot spot temperature.
18. Check the warnings reset limit (
signals until they disappears on the corresponding binary outputs. Take the HPTMPMAX
readings and compare with the reset level settings.
Verifying LOLINDAY and LOLINYRS outputs
1. Connect the test set for injection of three-phase currents to the appropriate current
terminals of the IED.
2. Make sure that the settings in the IED are appropriate, especially set the
setting as Enable,
3. Activate the TOTVALID input and set some temperature value in TOTEMP input.
4. Supply the IED with three-phase currents slightly more than the rated value.
5. Note the hot spot temperature (HPTMPMAX) and maintain it for another 1 hour.
6. Check the LOLINDAY and LOLINYRS outputs after 1 hour and compare it with the
calculated loss of life value using IEC standard method.
