Testing functionality by secondary injection
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
measurement with the setting
3.
Repeat steps 1 to 2 to find the operating time for the phase-to-earth fault according to
test point 12 in figure
setting
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.

FDPSPDIS
Prepare the IED for verification of settings outlined in Section
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.
Measure operating characteristics during constant current conditions. Keep the measured
current as close as possible to the rated value of its associated input transformer, or lower.
But ensure that it is higher than the set minimum operating current.
Ensure that the maximum continuous current to the IED does not exceed four times its rated
value, if the measurement of the operating characteristics runs under constant voltage
conditions.
