Comprehensive generator protection— connect the sel 700g across small, medium, or large generators for complete primary and backup protection. the sel 700gt provides an ieee 1547 compliant intertie protection solution for distributed generation. adding the optional neutral voltage connection to the sel 700g provides 100 percent stator ground. Comprehensive generator protection connect the sel 700g generator protection relay across small, medium, or large generators for complete primary and backup protection. adding the neutral voltage connection provides 100 percent stator ground protection, based on fundamental frequency and third harmonic neutral voltage measurements.
Use the optional, built in automatic synchronizer function in either the sel 700g generator protection relay or sel 400g to automatically synchronize the frequency, voltage, and phase angle of the generator and connect to the power system. this eliminates the need for expensive external synchronizing equipment. Sel 700g generator protection relay the sel 700g provides a comprehensive protection and synchronization solution for synchronous generators. with a built in autosynchronizer, flexible i o, and advanced communications, you can eliminate the complexity and cost of standalone synchronizer packages. unit protection.

The sel 700gw is configured with two sets of phase, negative sequence, and residual ground overcurrent elements, and phase, negative sequence, and residual ground time overcurrent elements to provide dual feeder protection in a multiwind generator network application. the relay also includes three pole breaker failure protection for two breakers. Combine the sel 700g generator protection relay or sel 400g advanced generator protection system with an sel irig b time source to measure the system angle in real time. the sel 700g offers a timing accuracy of ±10 μs, and the sel 400g is accurate to 1 μs. you can measure instantaneous voltage and current.
