Siemens has launched the new Reyrolle 5 series of digital protection relays, which can help protect transformers in substations.

The first device applications of the new generation of protection relay will be transformer protection in substations and overcurrent and earth fault protection. It includes comprehensive functionality as standard, with enhanced process data such as faults, events and waveform records enabling the power network to be effectively managed.

The small number of device variants allows easy ordering and efficient engineering while the improved hardware platform makes it even easier to operate and manage the protection relays.

As digitalization increases, a protection device must ensure a secure electricity infrastructure.

Thanks to its withdrawable design, Reyrolle 5 can be easily replaced without disturbing the switchgear connections. This reduces downtimes to a minimum and enables reliable and efficient lifecycle management.

Siemens already has more than 2.5 million numerical Intelligent Electrical Devices (IEDs) installed worldwide, thereof approximately half million of the Reyrolle protection relay series.
