Product Advantages and Features ABB REM615E_1G

1. Comprehensive Protection Functions, Ensuring Power Equipment Safety

   ABB REM615E_1G is equipped with a full set of protection algorithms optimized for medium-voltage equipment, covering overcurrent, earth fault, overvoltage, and other common faults in distribution networks. It supports configurable time-delay and instantaneous tripping modes, which can accurately identify fault types and avoid unnecessary power outages, effectively protecting transformers, motors, and feeders from damage.

2. High-Precision Measurement and Multi-Functional Monitoring

   ABB REM615E_1G realizes high-precision measurement of electrical parameters such as current, voltage, active power, reactive power, and power factor, with measurement accuracy up to ±0.2% for current and voltage. It can record fault wave data and operation events, providing a reliable basis for post-fault analysis and power system optimization.

3. Standardized Communication Protocols, Flexible System Integration

   ABB REM615E_1G supports international standard protocols such as IEC 61850 and Modbus, which can be seamlessly integrated into smart substation automation systems and industrial power monitoring platforms. The dual-channel communication design ensures data transmission reliability, and it can realize remote parameter configuration, fault diagnosis, and control without on-site operation.

4. Strong Environmental Adaptability and Easy Maintenance

   ABB REM615E_1G adopts industrial-grade reinforced hardware design, with built-in EMI filtering and surge protection circuits, which can resist electromagnetic interference, voltage fluctuations, and vibration impacts in industrial sites. The modular design of the relay facilitates on-site replacement and maintenance, and the human-machine interface (HMI) with LCD display allows for easy local parameter adjustment and status query.

Application Cases

1. Industrial Transformer Protection System

   In the 10kV transformer protection system of a petrochemical plant, ABB REM615E_1G monitors the transformer’s three-phase current, voltage, and temperature in real time. When an internal short circuit or overload fault occurs, the relay quickly issues a tripping command to cut off the power supply, avoiding transformer burnout. Its IEC 61850 communication function realizes data interaction with the plant’s power monitoring system, enabling remote real-time monitoring and fault alarm.

2. Medium-Voltage Motor Control System

   In the medium-voltage motor control system of a steel rolling mill, ABB REM615E_1G provides thermal overload protection and phase imbalance protection for the main rolling motor. It adjusts the protection curve according to the motor’s load characteristics, ensuring that the motor is not damaged by long-term overload operation. The RS-485 communication interface connects with the mill’s PLC system, realizing remote start-stop control and status monitoring of the motor.

3. Urban Distribution Network Feeder Protection

   In the 10kV feeder protection project of an urban distribution network, ABB REM615E_1G is installed in the distribution cabinet to realize fault detection and isolation of the feeder line. When a short-circuit fault occurs in a certain section of the line, the relay trips accurately to isolate the fault section, ensuring that other sections of the line can continue to supply power, improving the reliability of the distribution network.

Competitor Comparison

Selection Suggestions

1. For medium-voltage distribution networks, industrial transformer protection, and medium-voltage motor control scenarios that require high protection reliability and measurement accuracy, ABB REM615E_1G is preferred for its comprehensive functions and strong compatibility.
2. When selecting, confirm the rated voltage of the relay according to the actual power system voltage level, and match the appropriate CT and VT ratios based on the current and voltage ranges of the protected equipment.
3. For smart substation applications, prioritize the configuration of the IEC 61850 communication module to realize seamless integration with the substation automation system.

Precautions

1. When installing ABB REM615E_1G, wear an anti-static wristband to prevent static electricity from damaging the internal circuit board; ensure correct wiring of CT and VT to avoid reverse connection, which may cause protection misoperation.
2. Parameter configuration must be carried out in accordance with the ABB official manual, and the protection setting values should be adjusted according to the actual parameters of the protected equipment, avoiding blind configuration that may lead to protection failure.
3. During long-term operation, regularly check the tightness of the wiring terminals to prevent poor contact caused by vibration; regularly back up the configuration parameters to avoid data loss due to module failure.
4. In outdoor or harsh environment applications, install the relay in a sealed and waterproof cabinet, and configure a temperature control device to ensure the operating temperature is within the rated range.
