protection system. The zone-of-protection of a
line differential protection system is the feeder
section defined by the location of the current
transformers in the local and the remote
substation.

Combining horizontal GOOSE communication
over a station bus and binary signal transfer over
the protection communication link offers new
application possibilities beyond traditional line

based on inter-substation signal transfer is loss-of-
mains (LOM) protection in networks with
distributed generation. The performance of the
