The REF630 is a feeder protection and measurement device in the ABB Relion product family, a member of the 630 Protection Measurement and control device product family. Known for its functional scalability and flexible configuration, the device is suitable for use as primary protection for overhead lines and cable feeders in neutral neutral, resistance grounded, compensated or directly grounded distribution networks.

The REF630 design is available in four preconfigurations to meet typical feeder protection and control requirements, and can accommodate open/closed loop feeder applications, radiant overhead/hybrid line feeder applications, ring/mesh feeder applications, and segmented busbars. In addition, preconfiguration can easily meet the needs of specific applications with freely optional functionalities.

The device has two configurations: single bus and double bus, and each bus configuration has one or two circuit breakers and multiple switching device configurations. The REF630 also supports a large number of manual and electric disconnecting switches and ground switches, so it can be used to control many types of switchgear 186.

In terms of communication, the REF630 fully supports the substation IEC61850 communication standard, covering both vertical and horizontal communication, including GOOSE messages with switching signals and analog signals. In addition, the REF630 supports DNP3 (TCP/IP) and IEC 60870-5-103 (serial port) communication protocols, providing seamless connectivity to various substations and SCADA systems.

Key features of the REF630 also include a wide range of protection and measurement and control functions, a combination of highly sensitive and selective multi-frequency admittance ground protection, advanced and fast short-circuit, ground fault location functions, 8 RTD/mA input and 4 mA output, support for IEC61850 1st and 2nd editions, including GOOSE, It also supports Modbus, DNP3, IEC 60870-5-103 communication protocol 186.

ABB REF630 feeder protection relays need to be installed and configured in the following ways:

Check product integrity: The REF630 unit should be checked for integrity before installation, including all fittings and documentation.

Environment requirements: Ensure that the installation environment complies with ABB REF630 specifications, including temperature, humidity and other environmental factors.

Power configuration: Configure according to the REF630 power requirements to ensure power stability and reliability.

Communication Settings: Since the REF630 supports the IEC61850 communication standard and the DNP3 and IEC 60870-5-103 communication protocols, the communication parameters need to be set correctly to ensure seamless connection to the substation and SCADA systems.

Configure the protection function: Configure the protection function of the REF630 according to the specific application requirements, including overcurrent protection and ground fault protection, and set the corresponding value.

HMI configuration: The REF630 is equipped with a large and detachable HMI (Human Machine Interface) that needs to be configured according to operating habits and requirements.

Testing and verification: After installation and configuration, adequate testing and verification should be carried out to ensure that all functions of the REF630 are working properly and that protection actions are correct.

Comply with safety regulations: During the entire installation and configuration process, comply with relevant safety regulations and operating procedures to ensure the safety of personnel and equipment.

Full Life Cycle Service: ABB offers a wide range of product full life cycle services to ensure long-term stable operation and maintenance of the REF630.
