BE1-59N, Ground Fault Overvoltage Relay

This relay provides accurate 100% stator-ground protection for ungrounded and high-resistance grounded generators.


  • Limit generator damage with 100% stator ground-fault protection.
  • Wide range of applications covered with four overvoltage and four undervoltage setting ranges.
  • Meet protection timing requirements with instantaneous-, definite-, and inverse-time characteristics options.
  • Accurate detection of fundamental and third harmonic content using 40 dB harmonic filtering.
  • 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.
