BE1-47N, Negative Sequence Voltage Relay

Protects rotating equipment from the damaging effects of excessive negative-sequence voltage resulting from phase failure, phase unbalance, and reversed-phase sequence.

Benefits

  • Responds to true negative sequence voltage for greater accuracy.
  • Increased flexibility with wide settings range.
  • Minimized PT costs as a result of low sensing burden.
  • Reduced battery load with low burden power supply.
  • Accurate, repeatable, and reliable operation.
  • Simple HMI provides clear and intuitive settings for easy configuration.
  • LED targets provide clear annunciation of status.
  • Easily perform in-case system and device tests using test paddles.
