Section 10
Testing functionality by secondary injection
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.
The test procedure has to take into consideration that the shaped load encroachment
characteristic is active. It is therefore necessary to check the setting. To verify the settings
with the shaped load encroachment characteristic the test should be carried out according to
figures
activated tests according to the adjusted figures should be carried out.
To verify the settings for the operating points according to the following fault types should be
tested:
• One phase-to-phase fault
• One phase-to-earth fault
The shape of the operating characteristic depends on the values of the setting parameters.

The figures illustrating the characteristic for the distance protection function
can be used for settings with and without load encroachment. The solid lines
designate the diagram applicable when the load current compensation is
active. The solid line and all test points except 13 are valid for this case.
When the load current compensation is inactive, the dotted lines and test point
13 are valid. Test points 5, 6, and 7 are not valid for this measurement.
