Description Supply Voltage Monitoring Voltage
  • Monitors three-phase systems for phase imbalance
  • Detects phase failure even at 95% voltage feedback from the motor
  • Response delay: 0.5 s
  • Phase imbalance response threshold adjustable from 5 – 15 %
  • Phase sequence detection
  • Supply voltage = voltage being monitored
