BE1-11g Generator Protection System

Available in
fully drawout
half rack case

The BE1-11g is a multifunction numerical protection system that provides the comprehensive suite of functions for the protection of generators from faults and abnormal operating conditions. The BE1-11g provides three phase, ground, and negative sequence directional or non-directional overcurrent protection, forward or reverse power protection, VAR and impedance based loss of field, breaker failure, over/underfrequency, over/undervoltage and sync check, breaker monitoring and control, sequence-of-events recording, fault reporting, rate-of-change frequency, and metering functions, all in an integrated system.

Standard features include:

  • Each overcurrent element can be individually set for forward or reverse directional or non-directional control for maximum flexibility in any application.
  • Includes distance to the fault to aid in timely fault location and service restoration.
  • BESTlogicPlus provides the user with complete flexibility in configuring a protection and control system. User programmable variable and switch names make these relays completely self documenting.
  • Large high-contrast programmable 128x64 LCD display allows the relay to replace local indication and control functions, such as metering, alarm annunciation, and control switches.
  • Four "Table Lookup" time curves create custom curve shapes using 2-40 points
  • Three independent communication ports with protocol support allows integration with distributed control systems.
  • Optional RS-485 and copper or fiber Ethernet communications, Modbus™ , and DNP3 protocols
  • Available with optional IEC 61850 implementation
  • Web page and user-selectable email triggers for remote alarm reporting
  • High-speed BESTCOMSPlus™ user interface via USB
  • Power Quality reporting
  • Non-volatile expanded event memory
  • Includes Real Time Clock with 8 hour capacitor ride through and battery backup.
