REF615 Feeder protection measurement and control device

REF615 Feeder protection measurement and control device
The REF615 is a feeder protection measurement and control device from ABB, part of the 615 family of Relion® products. The unit is designed for substations and industrial distribution systems with protection, control, measurement, communication, monitoring and arc protection.
Key features of the REF615 unit include being compact, easy to disassemble, and developed and designed entirely on the basis of the international standard IEC 61850, enabling it to support the interoperability and horizontal communication of intelligent devices on site. In addition, it is suitable for radial, ring and grid distribution networks, with or without distributed power sources.
Specifically, the REF615 can be used for the protection, control, measurement and monitoring of public and industrial distribution systems, supporting neutral ungrounded grids as well as neutral resistance or impedance grounded grids. It also integrates various communication protocols such as IEC 61850 (which supports GOOSE communication), IEC 60870-5-103, and Modbus.
In summary, the REF615 is a full-featured, highly integrated feeder protection measurement and control device used in modern power systems to ensure safe, reliable and efficient system operation.

The REF615 is used in a wide range of industries and systems. The following main application areas can be summarized:
Power system: REF615 is mainly used for the protection and control of power substations, power plants and other power industries. It is suitable for medium voltage switchgear, transformers, motors, etc., providing comprehensive protection and control functions for these devices.
Industrial users: REF615 is also widely used in cement, metallurgy, petrochemical, automotive, semiconductor, paper, tobacco and other industrial users. In addition, it supports systems with distributed generators.
Municipal and Infrastructure: The device can be used in municipal, airport, port, real estate and other industries. This shows that its application in urban infrastructure and public service facilities is also very extensive.
Other industries: In addition to the above fields, REF615 is also used in water conservancy, transportation, petroleum, chemical, coal, metallurgy, power distribution network, data center, shopping malls, schools, hospitals, and new energy industries.
Smart grid and Automation systems: The REF615 can also be used in power automation systems and smart grids to achieve precise control and management of power transmission and distribution.
In short, the REF615 as a multi-functional feeder protection measurement and control device, its application range is extremely wide, covering almost all the areas that need power protection and control.
