ABB REG670 - Fwdr Fwdx; Test of Point RE

Verifying the settings by secondary injection
GUID-1752CE04-7C0F-4D37-9602-B22D8096DD2D v1
It is advised to connect the analog output channels of the function block OOSPPAM to
the internal disturbance recorder (and in particular to the function block A4RADR) in
order to perform a better analysis of the tests.
If the device is in test mode, the recording of the disturbances are enabled by the
setting in Main menu/Settings/IED Settings/Monitoring/Disturbance report/
DisturbanceReport/DRPRDRE:1: set the parameter OpModeTest to On.
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, Operation is set to On.
