SEL-700G Generator Protection Relay
SEL Generator Protection
The SEL-700G Relay is the right solution for utility and industrial generator protection, with an autosynchronizer, flexible I/O, and advanced communications. Apply the SEL-700G Relay for comprehensive primary and backup generator protection.
SEL-300G Generator Relay
SEL 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, a generator relay that includes several unique features designed for unsurpassed protection, monitoring, and control of electrical generators.
SEL-547 Distributed Generator Interconnection Relay
SEL Generator Protection
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.
SEL-2664 Field Ground Module
SEL Generator Protection
Add the SEL-2664 Field Ground Module to the SEL-300G Generator Relay to protect all the critical components in your generator with one comprehensive relay.
SEL-2664S 100% Stator Ground Protection
SEL Generator Protection
The SEL-2664S uses multisine signal injection to provide 100% stator ground protection 100 percent of the time. The relay works with the generator in or outof- service, including the generator ramp-up with no blind period.

SEL-2600 RTD Module
SEL Generator Protection, SEL Motor Protection, SEL Transformer Protection
SEL-2600 RTD is a microprocessor-based module, which can measure and transmit data from up to 12 RTDs and a single contact status located in transformers, breakers, motors, generators, or other system apparatus.
