IEC 61850 GOOSE (inter-device 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. For the devices
applications with protective functions have to be checked in terms of their required runtime. In each case, the manufac-
turer has to be consulted to define the requirements that ensure that the application functions safely.
