GE F35 l Feeder Protection System

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

Key Benefits

  • Cost-effective and flexible protection and control device for distribution feeder applications
  • Advanced IEC61850 Ed. 2 implementation, complete settings via SCL files and IEC 61850-9-2 process bus solution enable resource and platform managing optimization and reduce cost of ownership
  • Control schemes using hi-speed communications
  • High-end fault and disturbance recording, including internal relay operating signals
  • Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control
  • Accurate built-in metering functions eliminate auxiliary metering devices and reduce cost
  • Advanced automation capabilities provide customized protection and control solutions
  • Simplified system integration with communications supporting serial and Ethernet interfaces and multiple protocols
  • Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications
  • Ambient temperature monitoring with alarms when outside temperature exceeds upper thresholds
  • Supports English, French, Russian, Chinese, Turkish and German languages on the front panel, software and manuals
