Description

1. Parameter Specifications

• Power Supply: The REF610C11LCLR can operate on a wide – range power supply. It typically supports both AC and DC inputs, with AC input ranges from 85 – 265V and DC input ranges from 100 – 300V. The power consumption is relatively low, around 10 – 15W, which is energy – efficient for long – term operation in power systems.
• Measurement and Protection Functions:
  • Electrical Parameters: It can measure a variety of electrical parameters, including voltage (both single – phase and three – phase), current, power (active, reactive, and apparent), frequency, and power factor. The measurement accuracy is high, with voltage and current measurement accuracies typically within ±0.2%.
  • Protection Functions: It offers comprehensive protection functions such as over – current protection, over – voltage protection, under – voltage protection, and earth – fault protection. The protection settings can be configured according to the specific requirements of the power system.
• Communication Interfaces: It supports multiple communication protocols, including IEC 61850, Modbus TCP/IP, and DNP3. These interfaces allow for seamless integration with other devices in the power system, such as substation automation systems, SCADA (Supervisory Control and Data Acquisition) systems, and other intelligent electronic devices (IEDs).
• Sampling Rate: The REF610C11LCLR has a high – speed sampling rate, which can reach up to several thousand samples per second. This high sampling rate enables accurate measurement and fast response to electrical faults in the power system.

2. Applications

• Substation Automation: In electrical substations, the REF610C11LCLR is used for protection and monitoring of transformers, feeders, and busbars. It can detect electrical faults in a timely manner and initiate protective actions, such as tripping circuit breakers, to prevent damage to the power equipment and ensure the safety and reliability of the power supply.
• Industrial Power Systems: In industrial plants, it is used to monitor and protect the internal power distribution systems. For example, in a large – scale manufacturing plant, it can protect the motors, generators, and other electrical equipment from over – current and over – voltage conditions, ensuring the stable operation of the production process.
• Renewable Energy Power Plants: In solar and wind power plants, the REF610C11LCLR is used to monitor the power output and grid – connected performance. It can detect any abnormal electrical conditions in the power generation and transmission process and take appropriate protective measures to ensure the safe and efficient operation of the renewable energy power plants.

3. Weight and Dimensions

• Weight: The REF610C11LCLR weighs approximately 5 kg. Its weight is suitable for installation in standard substation cabinets and industrial control panels.
• Dimensions: It has dimensions of around 250 mm in width, 300 mm in height, and 200 mm in depth. These dimensions allow it to be easily installed in limited – space environments.

4. Features

• Comprehensive Functionality: It combines measurement, protection, and communication functions in a single device, providing a comprehensive solution for power system monitoring and protection.
• Flexible Configuration: The REF610C11LCLR can be easily configured using software tools. Users can customize the measurement and protection settings, as well as the communication parameters, according to the specific requirements of the power system.
• High – Speed Response: With its high sampling rate and fast – acting protection algorithms, it can quickly detect and respond to electrical faults, minimizing the damage to the power equipment and reducing the outage time.

5. Stability and Reliability

• Robust Design: The REF610C11LCLR is built with a sturdy housing that can withstand harsh environmental conditions, including high temperatures, humidity, and mechanical vibrations.
• Redundancy Options: It offers redundancy options for power supply, communication, and protection functions. Redundant power supplies can ensure continuous operation in case of a power failure, and redundant communication paths can guarantee reliable data transfer.
• Quality Assurance: The device is manufactured to high – quality standards and undergoes rigorous testing before leaving the factory. This ensures its long – term stability and reliability in power system applications.

6. Real – World Examples

• Urban Substation: In an urban substation, the REF610C11LCLR is installed to protect a 110kV/10kV transformer. It continuously monitors the electrical parameters of the transformer, such as voltage, current, and temperature. One day, it detected an over – current condition in the transformer due to a short – circuit fault in the downstream feeder. The REF610C11LCLR quickly issued a trip command to the circuit breaker, isolating the faulty section and preventing the damage to the transformer. The high – speed response and accurate protection function of the REF610C11LCLR ensured the stable power supply to the urban area.
• Wind Farm: In a large – scale wind farm, multiple REF610C11LCLR devices are used to monitor and protect the wind turbines and the power collection system. One of the devices detected a sudden drop in voltage in a wind turbine due to a grid – connected fault. It immediately sent a signal to the wind turbine controller to stop the turbine and isolate it from the grid. This preventive action protected the wind turbine from potential damage and ensured the safety of the entire wind farm.
