9. Click on ADD.

10. Now check your USB to Serial converter port no. From device manager. Lets suppose it is

“1”. Then write 1 and click on OK.

12. Click on OK.

13. Click on YES.

14. Always keep an eye on SPA address. It should be your com port no. Sometimes it becomes

zero or any other no.

15. You are done with the settings but always have a look on ATTRIBUTES in communication tab.

Relay name will be appearing the same as was selected in GENERAL tab. But just in case or if

some problem is coming in communication then have a look on it.

16. It should be same as was selected previously in GENERAL tab.

17. Now double click on right window RELAY SETTINGS TOOL.

18. Click on TRANSFERS and then select UPLOAD (Read from the Relay).

of 22


19. Click on ALL and then OK.

20. It should start reading settings from the relay. But IMPORTANT thing that don’t forget to

make relay CONFIGURATION>COMMUNICATION>SPA PORT>FRONT PORT. After some time

it will automatically go back to REAR PORT. So always check this setting before transferring

any thing to the relay or from the relay.

21. Now when the reading process is completed it means that no error should come during

reading. If it comes SOME SETTINGS WERE NOT READ then try reading again. When you are

done with reading a window like the one below will appear.

22. Now first tab is measurement tab. That is the measuring unit of the relay.

23. 2nd

tab is RECORDED DATA which is same as fault recorder.

24. 3rd

tab is SETTINGS. It is the main settings window. In which you can configure time delayed

and instantaneous O/C and E/F functions. When you click on SETTINGS you will find 5 more

tabs.

b. Protect Stages = O/C, E/F pick up and time settings.

d. SGF1 = O/P configuration for respective functions.

e. SGF2 = Configuration for O/C function

f. SGF3 = E/F configuration

g. SGF4 = O/C IDMT curve type

h. SGF5 = E/F IDMT curve type

of 22


i. SGR = Relay O/P configuration

of 22


25. In CONFIGURATION you can configure diff. Parameters.

26. INFO is about the relay serial no. N etc.

TESTING PROCEDURE:

27. Connect your freja current O/P to the relay Current I/P of any phase current coil. Lets say,

connect to RED phase coil of relay to O/P of freja. Inject current n check the pick up of the

relay for O/C.

28. Now inject in all other phases to check the pick up and similarly measure time.

29. Now connect your freja with neutral coil of the relay and inject current and check the pick up

of the relay for residual over current i.e. E/F and check its pick up and measure its time of

trip.
