Critical Communications for Smart Grid Protection
With protection schemes becoming increasingly sophisticated, IEC 61850 GOOSE messaging has emerged as the cornerstone of modern substation communications. This high-speed messaging protocol enables critical protection and control functions that traditional hardwired systems cannot match. For more details, select a day and time to talk to one of our sales engineers.
Understanding IEC 61850 GOOSE Communication
GOOSE (Generic Object Oriented Substation Event) messaging represents a fundamental shift in how protection signals are communicated within substations. Unlike traditional protocols, GOOSE operates at the data link layer, enabling precision timing solutions and network synchronization essential for peer-to-peer communication without routing delays.
