ABB 2RCA029395 Feeder Protection Terminal Product Documentation

1. Product Description
The ABB 2RCA029395 is a Feeder Protection Terminal specifically designed for feeder protection and control in power systems. This terminal adopts advanced digital signal processing technology and reliable hardware design to provide comprehensive protection, monitoring, and control for feeders in medium and low voltage distribution networks. It integrates multiple protection functions and high-precision measurement capabilities, making it suitable for feeder protection applications in industrial, commercial, and utility power systems, ensuring the safe and stable operation of the power grid1.

2. Detailed Parameters

3. Product Advantages and Features
3.1 Comprehensive Protection Functions: Provides multiple protection functions including overcurrent protection (instantaneous, definite time, inverse time), earth fault protection, over/under voltage protection, etc., ensuring feeder safety.
3.2 High-Precision Measurement: Uses advanced measurement technology to provide accurate electrical parameter measurements (current, voltage, power, etc.), supporting energy management and fault analysis.
3.3 Flexible Communication Capabilities: Supports multiple standard communication protocols (e.g., IEC 61850, Modbus, DNP3.0), facilitating integration with SCADA systems, substation automation systems, and other intelligent devices.
3.4 User-Friendly Interface: Provides a local display and operation interface for parameter setting, status monitoring, event recording, and fault diagnosis, easing operation and maintenance.
3.5 High Reliability Design: Adopts industrial-grade hardware design and strict quality control to ensure long-term stable operation in harsh environments, reducing maintenance needs.
3.6 Event Recording and Fault Oscillography: Built-in event recording (SOE) and fault oscillography functions record protection actions, operation events, and fault waveforms for post-event analysis and system optimization.

4. Application Fields
4.1 Industrial Power Systems: Used for distribution feeder protection in factories, mines, petrochemical plants, and other industrial sites to ensure the reliability of production power supply.
4.2 Commercial Buildings: Applied in power distribution systems of commercial complexes, hospitals, data centers, and other critical buildings to guarantee power supply safety.
4.3 Utility Grids: Used for feeder protection in urban and rural distribution networks to improve power supply reliability and power quality.
4.4 Renewable Energy Integration: Protects grid-connected feeders in renewable energy power plants (e.g., wind farms, photovoltaic power stations), ensuring the safe integration of clean energy into the grid.
4.5 Infrastructure Projects: Applied in power supply systems of large infrastructure such as airports, railways, and ports to support the stable operation of critical facilities.

5. Precautions
5.1 System Integration and Configuration: When integrating into an existing protection control system, ensure the terminal's communication protocols, regulations, and configurations match; professional personnel should perform parameter setting and function configuration if necessary.
5.2 Installation and Environment: During installation, ensure ambient temperature and humidity are within the allowed range (operating temperature -20°C to +60°C)2, maintain good ventilation, and avoid dust, corrosive gases, and strong vibrations.
5.3 Wiring and Grounding: Correctly connect current/voltage transformer signal lines, paying attention to polarity and phase; ensure reliable grounding to reduce electromagnetic interference and prevent protection maloperation or failure to operate.
5.4 Testing and Verification: Conduct comprehensive tests before commissioning, including protection function tests, communication tests, and coordination tests, to verify terminal performance and the correctness of protection settings.
5.5 Maintenance and Diagnostics: Regularly check the terminal's operational status; utilize self-diagnostic functions and event records to analyze equipment health; update software (firmware) promptly to keep the system up-to-date.
5.6 Safe Operation: When performing operations and maintenance, always follow safety procedures, ensure relevant circuits are safely isolated, and prevent electric shock or equipment damage.
