Zurich, August 19, 2024 – Today, Hitachi Energy achieved another milestone in extending its
distribution automation offering with the launch of the Relion REF650 multi-application
protection and control relay, specifically designed for medium-voltage power distribution grids.
Enhanced flexibility, modularity, security, and a new, intuitive user interface make the REF650
uniquely suited for the evolving power quality requirements across both utility and industrialoperations.
With growing complexity and increased digitalization in the distribution grid, electricalsubstations must be managed with higher fidelity. System components like protection andcontrol relays integrate critical data sources to operate distribution grids more autonomously
and responsively.
“Increasingly, demands on the system are not only related to the delivery of energy but also inthe smart adoption of new standards and technologies to make the system more resilient,interoperable, and efficient,” said Claus Vetter, Head of Automation and Communications
Global Product Group (GPG) for Hitachi Energy. “Automation and intelligent electronic devices(IEDs) can now work seamlessly to reduce disturbances, maintain high reliability, and loweropex.”
Distribution operators no longer want technologies and products that only do one thing. Instead,they want solutions that work together as a modular, scalable, and intelligent platform acrossthe network. They also want compliance with the latest standards and full interoperability
across diverse equipment and power sources. The REF650 marks further innovation in Hitachi
Energy’s record as a recognized leader in power automation and communication, delivering

technology that serves more than 50 percent of global utilities.
REF650 offers significant new features and benefits for the protection and control of primary
distribution systems in key areas: Cost-efficiency: single-device modular design is ideal for long-term deployment withscalable and flexible features
 Ease of use: new Human Machine Interface (HMI) touchscreen shows machine status
and real-time voltage/current data while giving an operator interactive control
 Performance and interoperability: REF650 is certified to the latest industry standards(IEC 61850 Ed 2.1), with PCM600 3.1, compatible across vendors
 Simplified engineering: streamlined configuration and parameterization allow for easiersettings changes, simplifying testing and maintenance processes Compact form factor: a smaller size significantly reduces the space needed forinstallation, especially in space-constrained environments
 Sustainable, safe, and secure: provides increased uptime with modular, userexchangeable hardware modules, and it supports extended operating temperature
ranges and vibration classes
 Enhanced after-sales service: can be reconfigured and extended with hardware
modules, offering flexibility in incorporating late project or design changes
Hitachi Energy’s Grid Automation portfolio enables customers to manage the evolving
demands of utility grids by delivering better visibility and scalable communications solutions
for increased performance, safety, and cost efficiency. The company also delivers advanced
services and digital capabilities, including integration of IT/OT, data analytics, anddigitalization tools to make the entire grid system more sustainable, flexible, and secure.
