1
Check that the required SARC is enabled in the RA24
2
For a current check scheme is the current check element enabled
and being picked up?
3
Check the GOOSE linkages in the Substation Project and ensure
that the correct sources and subscriptions have been established
4
Check that the Subscribing IED logic is consistent with the Subscribed
SARC. If required troubleshoot the logic by observing the
individual incoming signals are consistent with your test conditions for
example
Is the correct GGIO being received?
Is the quality bit being correctly treated?
Is the current check qualification being asserted
5
Using the RA24 Web Browser check for any error messages on the
Status screen when you FTP the .cid file into the device
6
In the Web Browser observe the trip status when a Sensor is
triggered
7
Using and IEC61850 browser such as IED Scout observe the trip
