Observe that the zones that are not tested have to be blocked and the zone that is
tested has to be released.

4.

Repeat steps 

1

 to 

3

 to find the operating value for the phase-to-earth fault L3–E

according to figure 

15

 and table 

18

.

Test points 8, 9. 10 and 11 are intended to test the directional
lines of impedance protection. Since directionality is a common
function for all 5 measuring zones, it is only necessary to test
points 8, 9. 10 and 11 once in the forward direction in order to
test the accuracy of directionality (directional angles).
Directional functionality testing (trip inside, no-trip outside)
should always be made for all impedance zones set with
directionality (forward or reverse).

10.4.1.2 

Measuring the operating time of distance protection zones

Procedure:

1.

Subject the IED to healthy normal load conditions for at least two seconds.

2.

Apply the fault condition to find the operating time for the phase-to-phase fault
according to test point 12 in figure 

14

 and table 

17

 for zone 1. Compare the result

of the measurement with the setting 

t1PP

.

3.

Repeat steps 

1

 to 

2

 to find the operating time for the phase-to-earth fault

according to test point 12 in figure 

15

 and table 

18

. Compare the result of the

measurement with the setting 

t1PE

.

4.

Repeat steps 

1

 to 

3

 to find the operating time for all other used measuring zones.

Observe that the zones that are not tested have to be blocked and the zone that is
tested has to be released.

10.4.1.3 

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.

10.4.2 

Phase selection with load encroachment, quadrilateral

characteristic FDPSPDIS

Prepare the IED for verification of settings outlined in section 

"Preparing the IED to

verify settings"

.

The phase selectors operate on the same measuring principles as the impedance
measuring zones. So it is necessary to follow the same principles as for distance
protection, when performing the secondary injection tests.
