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 relay's pickup con-
dition, GOOSE is not generally qualified for protection-relevant applications. The protective application is to
be checked with regard to the required transmission time and cleared with the manufacturer.
