Overview

Built on the industry-leading UR platform, the G60 offers superior protection for medium and large generators, including large steam and combustion turbines, combined cycle generators, and multi-circuit hydro units. The G60 may also be used on pumped storage generators without needing to switch the CT secondary circuitry. It provides advanced communication with an integrated, fully managed Ethernet switch, reducing network installation costs while supporting industry-standard communication protocols.

Key Benefits

• Secure Protection: High-speed protection elements compliant with IEEE C37.102 for complete generator protection.
• IEC 61850 Certification: Advanced implementation ensures interoperability, device managing optimization, and reduced cost of ownership through complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE, IEC 61869, or IEC 61850-9-2 Hardfiber).
• Routable GOOSE (R-GOOSE): Enables GOOSE messages to extend beyond the substation for wide area protection and control applications.
• Cyber Security: Advanced features like “CyberSentryTM” meet modern industry requirements.
• Phasor Measurement Unit: Supports synchrophasors according to IEEE® C37.118 (2011) and IEC® 61850-90-5.
• Application Flexibility: Multiple I/O options, including high-density I/O, programmable logic, modularity, and specific customization.
• Integrated Display: A large, full-color display provides real-time visualization and control via a bay mimic, along with annunciator functionality and graphical visualization of phasors.
