Protection of electrical grids
We provide digital protection for power systems: busbar, differential, distance, overcurrent, voltage, frequency, and combined protection, transient and fault recording, monitoring, and diagnostics.
The SI(emens) PROTEC(tion) devices lead the way in integrating protection, control, measurement, and automation functions in one unit.
Thanks to the homogeneous system platform and extensive experience of more than a million successfully operating devices in the field worldwide, SIPROTEC enjoys top recognition among users. SIPROTEC is the industry standard for digital protection technology today.
- In many fields of application, all secondary technical functions can be carried out using just one device. This lowers investment costs, reduces installation work in every respect, and increases system availability.
- The implementation of the international IEC 61850 standard has played a significant role in forming a consistent and future-proof basis for all protection, communications, and control functions.
- The trendsetting system architecture places communication firmly under the engineer’s control. Powerful, flexible, and, above all, reliable communication is the most important prerequisite for distributed and decentralized systems such as smart grids.
- The implementation of IEC 61850 edition 2 unfolds the entire potential of this standard by optimally supporting operational needs and making handling easy.
