ABB REF610C11HCNN01

Product introduction

The ABB REF610C11HCNN01 is a high – performance feeder protection Intelligent Electronic Device (IED) that plays a crucial role in safeguarding utility and industrial distribution power systems. As part of ABB’s renowned Relion® product family and the 610 product series, this device is engineered to provide comprehensive protection, accurate measurement, and reliable supervision of electrical networks.

The REF610C11HCNN01 comes with a dedicated base, which simplifies the installation process, whether it’s a new setup or a retrofit project. It acts as a central unit for protecting incoming and outgoing feeders in distribution substations, especially in resistance – earthed and solidly – earthed power systems. Additionally, its design makes it suitable for use in challenging marine and off – shore environments, where reliability is of utmost importance.

Core advantages and technical highlights

Comprehensive protection functions

The REF610C11HCNN01 offers a wide array of protection features. Its three – phase overcurrent protection, with low – set, high – set, and instantaneous stages, can quickly detect and respond to abnormal current levels. For example, in an industrial plant where sudden overloading of machinery can occur, the low – set overcurrent protection can be configured to detect minor overcurrents and take preventive action, while the high – set and instantaneous stages are ready to handle more severe faults.

The non – directional earth – fault protection, having both low – set and high – set stages, is vital for ensuring the safety of personnel and equipment. In a substation, if an earth – fault occurs, the low – set stage can be used for early detection and isolation of the fault, while the high – set stage is designed to deal with more significant earth – faults.

Phase discontinuity and thermal overload protection further enhance the device’s ability to protect electrical systems. Thermal overload protection is particularly useful in protecting motors and transformers from overheating due to prolonged overloading.

The circuit – breaker failure protection feature adds an extra layer of security. In case a circuit – breaker fails to operate as expected during a fault, the REF610C11HCNN01 can detect this and take alternative actions to isolate the faulty section of the network.

The arc protection, with two lens sensors, provides fast substation busbar arc – fault protection. In a substation, an arc – fault can cause significant damage in a short time. The REF610C11HCNN01’s arc protection can detect and clear such faults within milliseconds, minimizing the impact on the power system.

Accurate measurement and recording

With the ability to measure residual current and three – phase current, the REF610C11HCNN01 provides valuable data for system monitoring and analysis. In a power distribution network, accurate current measurement helps in load balancing, energy management, and early detection of potential faults.

The disturbance and event recording function is essential for troubleshooting. It logs detailed information about any abnormal events in the electrical system, such as voltage sags, surges, or short – circuits. This data can be used by maintenance personnel to analyze the root cause of a problem and take appropriate corrective actions.

Advanced communication capabilities

Supporting multiple standard communication protocols like IEC 61850, IEC 60870 – 5 – 103, DNP 3, Modbus, Profibus, and SPA, the REF610C11HCNN01 can be seamlessly integrated into modern control systems. In a smart grid environment, where different devices need to communicate with each other, the REF610C11HCNN01 can exchange data with other IEDs, control centers, and SCADA systems, enabling remote monitoring and control of the power system.

Robust design for harsh environments

Rated to operate within a temperature range of – 25°C to + 55°C and humidity range of 0 – 95% (non – condensing), the REF610C11HCNN01 can withstand extreme environmental conditions. In a desert – based power plant, where high temperatures and low humidity are common, or in a coastal substation with high humidity, the device can maintain its reliable performance.

Its resistance to vibrations and shocks, which are typical in industrial and marine settings, ensures that it can function properly even in the vicinity of heavy machinery or in a ship’s engine room.

Compact and user – friendly design

The compact size of the REF610C11HCNN01, along with its easy – to – install base, makes it suitable for applications where space is limited. In a crowded substation control cabinet, the device can be installed without taking up excessive space.

It comes with a user – friendly interface, equipped with an intuitive display and control panel. Operators can easily configure the device, monitor its status, and access the recorded data without requiring extensive training.

Typical application scenarios

Power distribution substations

In a medium – voltage distribution substation, the REF610C11HCNN01 is used to protect incoming and outgoing feeders. It continuously monitors the electrical parameters of the feeders and quickly responds to any faults. For example, if a short – circuit occurs in an outgoing feeder supplying power to an industrial area, the REF610C11HCNN01’s overcurrent protection will detect the fault and trip the associated circuit – breaker, isolating the faulty section and preventing damage to other parts of the network.

Industrial plants

In an industrial plant, the REF610C11HCNN01 can be used as backup protection for motors, transformers, and generators. For a large – scale manufacturing plant with multiple motors and transformers, the device’s thermal overload protection can protect the motors from overheating due to long – term overloading. In case of a motor burnout, the REF610C11HCNN01 can detect the abnormal current and voltage changes and take appropriate actions, such as sending an alarm to the control room and tripping the motor’s circuit – breaker.

Marine and off – shore installations

In a ship’s power system, the REF610C11HCNN01 can protect the electrical network from various faults. The device’s ability to operate in harsh marine environments, with its resistance to salt – water corrosion, humidity, and vibrations, makes it an ideal choice. For example, in an off – shore oil rig, where reliable power supply is critical for operations, the REF610C11HCNN01 can protect the power distribution system from earth – faults, overcurrents, and arc – faults, ensuring the continuous operation of the rig’s equipment.

Installation, commissioning and maintenance instructions

Installation preparation

Before installation, ensure that the DIN rail (if using DIN – rail mounting) or the mounting surface (for flush mounting) is clean, securely mounted, and grounded. Use appropriate tools, such as screwdrivers and pliers, and follow safety procedures.

Check the power supply voltage to ensure it is within the specified range of 24 – 250 V DC or 110 – 240 V AC. The power supply should be properly fused to protect the device from overcurrent.

When wiring the device, use appropriate gauge cables (recommended 2.5 – 4 mm² for power connections and 1 – 1.5 mm² for signal connections) and ensure that the connections are tight and properly insulated. Follow the wiring diagram provided in the product manual to correctly connect the inputs, outputs, and communication interfaces.

If installing in a harsh environment, consider using additional protective enclosures or coatings to further protect the device from dust, moisture, and corrosive substances.

Commissioning steps

After installation, use ABB’s dedicated commissioning software or the device’s built – in configuration interface to set up the protection and measurement parameters. Configure the overcurrent, earth – fault, and other protection settings according to the requirements of the power system.

Test the communication interfaces by connecting the REF610C11HCNN01 to a test device or a control system. Ensure that data can be sent and received correctly using the selected communication protocol (e.g., IEC 61850, Modbus).

Perform a series of functional tests, such as simulating overcurrent, earth – fault, and arc – fault conditions, to verify that the device’s protection functions are working correctly. During these tests, observe the device’s response, such as the activation of alarm signals and the tripping of circuit – breakers.
