IEC 61850 GOOSE (inter-device communication)
The GOOSE communication service of IEC 61850 is qualified for switchgear interlocking. Since the transmis-
sion time of GOOSE messages depends on both the number of IEC 61850 clients and the pickup condition of
the device, GOOSE is not generally qualified for protection-relevant applications. The protection application
must be checked with regard to the required transmission times and coordinated with the manufacturer.
