GE F35 l Feeder Protection System
The F35, a member of the UR Family of protection relays, provides cost-effective feeder protection, control and metering for up to five feeders with busbar voltage measurement, or six feeders without busbar voltage in one integrated package. Use the F35 as a stand-alone device or as a component of an automated substation control system.
Application
- Primary protection and control for multiple distribution feeders
- Distribution load shedding schemes based on voltage and frequency elements
- Busblocking/interlocking schemes
- Throwover schemes (bus transfer scheme applications)
- Distributed generation (DG) interconnect protection, including active and passive anti-islanding
