10. Reverse the direction of the injected current and check that the step does not

operate.

11. Check that the protection does not operate when the polarizing voltage is zero.
12. Repeat the above-described tests for the higher set steps.
13. Finally, check that start and trip information is stored in the event menu.

15.6.5.1 

Completing the test

Continue to test another function or end the test by changing the 

Test mode

 setting

to 

Off

. Restore connections and settings to their original values, if they were

changed for testing purposes.

15.6.6 

Sensitive directional residual overcurrent and power

protection SDEPSDE

Prepare the IED for verification of settings outlined in section 

 "Overview"

 and

section 

 "Preparing for test"

 in this chapter.

Figure 

93

 shows the principal connection of the test set during the test of the

sensitive directional residual overcurrent protection. Observe that the polarizing
voltage is equal to -3U
