Description
ABB RED615
Technical Specifications:
- Function: Overcurrent, Earth Fault, and Feeder Protection
- Application: Medium Voltage Distribution Networks
- Standards: Compliant with IEC and ANSI/IEEE protection standards
Functional Features:
- Comprehensive Protection: Features non-directional and directional overcurrent and earth fault protection.
- Integrated Control: Includes circuit breaker control, autoreclosing, and interlocking logic.
- Advanced Metering: High-accuracy measurement of voltage, current, power, and energy.
- Event Recording: Extensive fault and disturbance recording for post-event analysis.
Application Scenarios:
Deployed in utility distribution substations, industrial power plants, and commercial building power distribution systems.
Performance Parameters:
- Accuracy: High-precision current and voltage measurement for reliable protection tripping.
- Response Time: Fast and deterministic tripping times to isolate faults and minimize system downtime.
Material Composition:
Robust metal enclosure with high-quality internal relays, precision current transformers, and isolated communication interfaces.
Structural Features:
Available in flush, surface, or rack-mounted configurations. Features a local Human-Machine Interface (HMI) with a backlit display and navigation keys.
Working Principle:
Continuously samples electrical waveforms via CTs and VTs. An internal digital signal processor analyzes the data against configured protection curves and logic, issuing trip commands to circuit breakers when faults are detected.
Installation Requirements:
Mount in a clean, dry environment. Connect current and voltage circuits with extreme care, ensuring correct polarity and proper shorting of CTs when disconnected.
Usage Precautions:
Always perform secondary injection testing to verify protection settings before energizing the primary equipment. Handle the relay with ESD precautions.
