GE Dolin G60 generator protection system

The G60 is built on the industry-leading UR platform, providing outstanding protection for medium and large generators, including large steam and internal combustion engine turbines, combined cycle generators and multi-loop hydroelectric generating units. The G60 can also be used in pumped storage generators without switching the secondary circuit of the CT. The G60 provides advanced communication through an integrated fully managed Ethernet switch, reducing network installation costs while supporting industry-standard communication protocols.

Main advantages

Safe and high-speed protection components can achieve complete generator protection and comply with the IEEE C37.102 standard

Advanced IEC 61850 1st and 2nd edition certification implementation, complete setup through SCL documents and flexible process bus support (IEC 61850-9-2LE, IEC 61869 or IEC 61850-9-2 hard fibers) ensure interoperability, optimize equipment management and reduce ownership costs

Routable GOOSE (R-GOOSE) enables GOOSE messages to go beyond substations, thereby achieving wide-area protection and control applications

The advanced cybersecurity feature "CyberSentryTM" helps meet the requirements of modern industries

Phasor measurement unit (synchronous phasor) in compliance with IEEE® C37.118 (2011) and IEC® 61850-90-5 support

Application flexibility with multiple I/O options, including high-density I/O, programmable logic, modularization and specific customization

The integrated large full-color display screen provides real-time visualization and control of the protected bracket through bracket simulation and graphical visualization of the signaler function and phasor

Additional transformer differential protection components are used for step-up transformer protection through a device
