Description

ABB REU615 HBUAEAADANB6ANN1XG

Technical Specifications:

  • System Family: Relion 615 Series.
  • Protection: Overcurrent, earth fault, directional protection, and voltage supervision.
  • Control: Circuit breaker control, auto-reclosing, and interlocking.

Functional Features:

  • Directional Protection: Accurate fault direction determination for ring and parallel feeder networks.
  • Auto-Reclosing: Configurable multi-shot reclosing sequences to restore transient faults.
  • Arc Protection: Optional integrated arc flash detection.

Application Scenarios:

  • Utility distribution substations.
  • Industrial power distribution networks.
  • Renewable energy collection grids.

Material Composition & Structural Characteristics:

  • Plug-in Module: Facilitates rapid replacement and maintenance.
  • Local HMI: Clear display of measurements, statuses, and active alarms.

Working Principle:
Monitors line currents and voltages to detect abnormal conditions. Directional elements use phase angle comparisons to determine fault location, ensuring selective isolation of the faulted section.

Installation Requirements:

  • Connect voltage and current transformers according to the wiring diagram.
  • Configure the auto-reclosing scheme in coordination with upstream and downstream protection.

Usage Precautions:

  • Verify directional element polarity during commissioning.
  • Ensure arc flash sensors are correctly positioned and tested.
