Built on the industry-leading UR platform, the G30 provides advanced protection for small to medium-sized steam, hydraulic and combustion-turbine generators. The G30 is also well suited for applications where both the generator and transformer are in the same zone of protection, providing the required protection in one device. The G30 provides advanced communication with an integrated managed Ethernet switch, while supporting standard communication protocols including IEC 61850.
Key Benefits
Complete protection for small to medium-sized generators and transformers
Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
Combined generator and transformer protection
Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control
Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
High-speed peer-to-peer communications allowing reduction of relay-to-relay wiring and associated installation costs
An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors
Applications
