REF615 is a digital feeder protection and measurement control device produced by ABB, mainly used in public and industrial power distribution systems. The following is its detailed introduction:

Functional characteristics

Protection functions: It features directional and non-directional overcurrent and ground fault protection, as well as voltage, frequency and power-based protection and measurement functions. It also features a unique multi-frequency admittance ground fault protection to enhance sensitivity and selectivity. It can be optionally equipped with advanced and rapid short-circuit and ground fault location, arc protection and high-speed output.

Control function: It can realize the control of overhead lines and cable feeders, support multiple communication protocols, such as IEC 61850, IEEE 1588v2, Modbus, DNP3 and IEC 60870-5-103, etc., and facilitate data exchange and remote control with other equipment or systems.

Measurement and monitoring: It can monitor parameters such as current, voltage and power in real time. The device can record system events and fault conditions, and generate alarm information to assist operation and maintenance personnel in fault diagnosis and system optimization.

Product advantages

Flexible configuration: There are multiple standard configurations to choose from, and configuration changes can be made through the graphical signal matrix or the protection and control IED manager PCM600, which can adapt to different applicatio

n scenarios and specific user requirements.

Easy installation: It adopts a withdrawable unit design, which is convenient for installation and testing. It is equipped with a large LCD screen, which can display single-line graphs. It can be accessed through a local or web browser-based human-machine interface (HMI), and the operation is convenient.

High reliability: Supports the IEC 61850 communication standard and related redundancy protocols, such as Parallel Redundancy Protocol (PRP) and High Availability Seamless Redundancy Protocol (HSR), to ensure the reliability and stability of communication. Meanwhile, it is equipped with advanced protection functions and self-diagnostic capabilities, which can effectively protect the power system and promptly detect its own faults.

REF615 offers a comprehensive and reliable protection, control, measurement and monitoring solution for feeders in power systems, which helps enhance the stability and reliability of power systems and reduce operation and maintenance costs
