Siemens introduces Reyrolle 5 series of protection relays

November 13, 2019 - With the Reyrolle 5 series of protection relays, Siemens is developing its offerings for medium-voltage and industrial power networks. The protection, control, monitoring and measuring of power networks is a vital element in managing electrical assets, increasing reliability, sustainability and the safety of operating personnel. The first device applications of the protection relay will be overcurrent and earth fault protection and transformer protection in substations. It includes functionality as standard, with process data such as faults, events and waveform records enabling the power network to be effectively managed. The small number of device variants allows ordering and engineering while the hardware platform helps to operate and manage the protection relays.

As digitalization increases, a protection device must ensure a secure electricity infrastructure. The Reyrolle 5 includes cyber security features such as digitally signed firmware and these will be enhanced with future product releases along with security patches to address any specific threats. Reyrolle 5 offers a design with a graphical display, tactile pushbuttons, programmable LEDs, and the Reydisp software. The protection relay already provides functionalities like power supply, configurable digital input thresholds, current and voltage transformer connections, and serial and Ethernet communication. All communications protocols are also included as standard.
