Testing
 IEC 61850 Closed-loop relay testing
 The interested power system is simulated in RTDS
 Bus voltages and breaker currents at certain location are sent to the external physical IEDs (IEC
61850 9-2LE or 61869-9 compatible) through SV messages
 Breaker status and tripping/reclosing signals are exchanged through GOOSE messages
