Apply SEL generator protection products and avoid expensive equipment damage and failure while maintaining system performance and increasing availability. SEL quality-tested features provide complete primary and backup protection from all types of faults. Upgrade to an SEL world-class protection system today, and be confident that your generation system will be working tomorrow.
Advantages of SEL Generator Protection
View generator autosynchronizer, Sequential Events Recorder (SER), and 180-cycle oscillographic event reports to analyze generator startup, shutdown, or system faults. Measure electrical, thermal, and generator run-time quantities. Record accumulated breaker contact wear with the breaker monitor function, which uses manufacturer specifications for defining breaker operation limits. The internal monitor tracks the total number of close/open operations and integrates interrupted current per phase.
The SEL-700G is the right solution for utility and industrial generator protection, with an autosynchronizer, flexible I/O, and advanced communications. Apply the SEL-700G for comprehensive primary and backup generator protection.
In order to make technology available for the first time that complies with IEEE turbine protection standards, SEL has applied its expertise in the production of microprocessor-based relays to create the SEL-300G. SEL designed the SEL-300G to meet the needs of a variety of users, including utility and industrial power plants and generator set manufacturers.
Add the SEL-2664 to the SEL-300G or SEL-700G to protect all the critical components in your generator with one comprehensive relay. Or, add the SEL-2664 to the SEL-2664S to complete ground fault protection on both the rotor and stator.
Protect high-impedance grounded generators from ground faults at standstill, during startup, and while running by using the multisine frequency injection and neutral overvoltage-based protection in the SEL-2664S.
Apply the flexible SEL-547 at the transfer switch site (interconnection point between the utility and the customer) and at each individual generator site. When the SEL-547 at the transfer switch site detects utility supply problems, it separates the customer system from the utility supply. When the SEL-547 at an individual generator site detects a system problem that could adversely affect the generator, it separates the individual generator from the rest of the system. The SEL-547 product flyer figures show examples of the SEL-547 “in action” at the transfer switch site and at an individual generator site. Other applications and scenarios are possible.
Measure and transmit data from up to 12 RTDs and a single contact status located in transformers, breakers, motors, generators, or other system apparatus.
