Protecting Grids with Confidence

The protection, control, monitoring and measuring of our power networks is a vital element in managing our electrical assets, increasing reliability, sustainability and the safety of operating personnel. Our goal is to provide protection devices which provide flexible solutions and easy integration into an energy market which is becoming increasingly decentralized and digitalized. With the new Reyrolle5 we have listened to the changing needs of our customers. Building on our 100-year history of developing protection relays we have used proven algorithms to ensure reliable performance. With IEC 61850 Ethernet communications as standard and enhanced cyber security the Reyrolle 5 enables substation digitalization.The user friendly, intuitive design and minimal ordering variants gives confidence to the user and this extends to the Reydisp programming software tools.
