Digital Surveillance Relay for Three-Phase Voltage with Neutral Conductor

This digital surveillance relay is designed for three-phase voltage monitoring with a neutral conductor. It features automatic phase sequence correction and detects phase failures.

Features:

  • Phase failure detection (3 x 90 to 400 V)
  • Frequency range: 50 to 60 Hz AC
  • Under- and overvoltage protection (90-400 V)
  • Hysteresis: 1-20 V
  • Delay to OFF: 0-20 s
  • Asymmetry: 0-20%

Outputs:

  • 1 CO for phase correction
  • 1 CO for line supply failure at the terminal

The relay utilizes screw terminals for connection.
