Multilin G30

Generator Protection Systems

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 IEC61850 Ed. 2 certified implementation, complete settings via SCL files and IEC 61850-9-2 process bus solution enable resource and platform managing optimization and reduce 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

Small to medium-sized generators typically driven be steam, gas or hydraulic turbines
Distributed generation (DG) interconnect protection
Combined generator and transformer in the zone of protection
Pumped storage generators
