Section 11
Testing functionality by secondary injection
1. Check the Application Configuration: verify that hardware voltage and current channels of the
IED are properly connected to SMAI function blocks, and that the proper analog outputs of
SMAI's are connected to the analog inputs of the function block OOSPPAM.
2. Connect three-phase voltage channels of the test set to the appropriate IED terminals.
3. Connect in parallel two groups of three-phase currents of the test set to the appropriate IED
terminals.
4. Connect the appropriate trip output of the IED to the input channel of the test set that
monitors the trip.
5. Go to Main menu/Settings/IED Settings/Impedance protection/OutOfStep(78,Ucos)/
OOSPPAM(78,Ucos):1, and make sure that the function is enabled, that is,
On .

The trajectory of the impedance does not enter the lens characteristic.
Preliminary steady state test at 50 Hz
• Go to Main menu/Test/Function status/Impedance protection/OutOfStep(78,Ucos)/
OOSPPAM(78,Ucos):1/Outputs to check the available service values of the function block
OOSPPAM.
• Apply the following three-phase symmetrical quantities (the phase angle is related to phase
L1):

• Check that the service values (VOLTAGE, CURRENT, R(%), X(%)) are according to the injected
quantities and that ROTORANG is close to 0 rad.
