SEL-700G-Generator Protection Relay

The SEL-700G is the right solution for utility and industrial generator protection, with an autosynchronizer, flexible I/O, and advanced communications. It provides a complete protection and synchronization solution for synchronous generators, so you can eliminate the complexity and cost of standalone synchronizer packages. Integrating the synchronization capability into the generator protection relay provides the most cost-effective and reliable solution.

The 5-inch, 800 x 480 color touchscreen display option allows you to directly set, monitor, and control your system. A small form factor and multiple mounting adapters make it easy to upgrade protection without cutting or drilling existing cutouts. You can quickly integrate the SEL-700G into serial- or Ethernet-based communications with IEC 61850 Edition 2, IEC 60870-5-103, the IEC 62439 Parallel Redundancy Protocol (PRP), Mirrored Bits communications, Modbus, DNP3, and other protocols.
