IEC 61850 GOOSE (inter-relay communication)
The GOOSE communication service of IEC 61850 is qualified for switchgear interlocking The runtime of
GOOSE messages with the protection relay picked up depends on the number of connected IEC 61850
clients.
As from version V4.6 of the devices, applications with protective functions have to be checked with regard
to their required runtime. In individual cases, the manufacturer has to be consulted with regard to the
requirements to ensure that the application functions safely.
