Standard features include:

  • Compact design requires minimal panel space for underfrequency and undervoltage load shedding applications.
  • Adds Oscillography, Sequence of Events, and Metering when single function voltage relays are replaced with the BE1-700V.
  • Zero sequence voltage (3V0) used to detect single phase ground faults on high resistance or ungrounded systems can be calculated based on the applied 3-phase 4-wire sensing voltage, or applied from a separate zero sequence source (optional  VX input).
  • With the optional 4-shot recloser, provides economical replacement of existing distribution feeder automatic reclosing relays.
  • With the optional 4-shot recloser, including a pilot initiate path and auxiliary voltage input, replace existing network (transmission, sub-transmission) automatic reclosing schemes.
  • BESTlogic 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.
  • Programmable LCD display allows the relay to replace local indication and control functions such as panel metering, alarm annunciation, and control switches.
  • Two independent communication ports with protocol support allows integration with distributed control systems.
  • Optional BESTNet Ethernet package provides metering and status web pages, settings and configuration via Ethernet, and email notification of user-defined events.
  • BESTCOMS GUI software available to aid in setup.
