ekorDPF

Electronic fault detection unit developed for its use in the feeder function. Its main applications are fault detection and indication, presence or absence of voltage, thus avoiding any incorrect indication.

Technical Features:

• Overcurrent detection (50 - 51, 50N - 51N)
  • Subject to absence of voltage
• Auxiliary contact for fault indication
• Earth fault detection from 0.5 A
• External power supply
• Current metering
• Toroidal transformers installed in the bushings
• Inverse curve in the earth unit for coordination
• Capacitive current filtering
• Power supply module and local indication
