Protection DevicesSIPROTEC and Reyrolle Device SeriesSolutions for today's and future power supply systems –for more than 100 yearsWith the two brands SIPROTEC and REYROLLE, Siemens is theworld market leader in digital protection technology. Profit fromthe experience out of an installed base of more than 1 milliondevices and 500,000 with IEC 61850.SIPROTEC has established itself on the energy market for decades as a powerful and complete system family of numericalprotection relays and bay controllers from Siemens.SIPROTEC protection relays from Siemens can be consistentlyused throughout all applications in medium and high voltage.With SIPROTEC, operators have their systems firmly and safelyunder control, and have the basis to implement cost-efficientsolutions for all duties in modern, intelligent and “smart” grids.Users can combine the units of the different SIPROTEC deviceseries at will for solving manifold duties – because SIPROTECstands for continuity, openness and future-proof design.As the innovation driver and trendsetter in the field of protection systems for 100 years, Siemens helps system operatorsto design their grids in an intelligent, ecological, reliable andefficient way, and to operate them economically. As a pioneer,Siemens has decisively influenced the development of numericalprotection systems (fig. 2). The first application went into operation in Würzburg, Germany, in 1977. Consistent integration ofprotection and control functions for all SIPROTEC devices wasthe innovation step in the 90ies. After release of the communication standard IEC 61850 in the year 2004, Siemens was thefirst manufacturer worldwide to put a system with this communication standard into operation.How can system operators benefit from this experience? Proven and complete applications Easy integration into your system Highest quality of hardware and softwareFig. 2 SIPROTEC – Pioneer over generations4 Selection Guide for SIPROTEC and Reyrolle · Edition 6Fig. 1 Siemens protection devices Excellent operator friendliness of devices and tools Easy data exchange between applications Extraordinary consistency between product- and systemengineering Reduced complexity by easy operation Siemens as a reliable, worldwide operating partnerReyrolleThe products of the long-standing British manufacturer Reyrolleare considered especially powerful and reliable by many markets. With the latest numerical products, Reyrolle – as a part ofSiemens – shows that the development is being pushed forward,and that new innovations are continuously being developedfurther for the users' benefit. In this way, Reyrolle completes theofferings for protection devices, particularly in Great Britain andthe Commonwealth countries.
