Why Line differential protection?
The SIPROTEC 7SD80 is a line differential protection relay. It provides selective line protection for power cables and overhead lines up to 24 km, supporting all types of starpoint configurations. Ensuring fast and stable line protection in industrial and distribution grids is crucial. Our SIPROTEC 7SD80 features an implemented phase comparison algorithm for reliable and efficient safeguarding of your lines. The phase comparison algorithm delivers rapid and stable protection, minimizing downtime and enhancing grid reliability. Communicate directly without external equipment using copper wires, optical fibers or both in redundancy for flexible protection for your infrastructure.
Key benefits
Boost system availability and operational reliability
Ethernet redundancy protocols (PRP, HSR and RSTP) increase system availability. This enables fast, selective tripping even if relay communication fails, to protect your power cables and overhead lines.
Simplify protection concepts and reduce costs
Implement simplified, cost-saving protection for meshed grids and busbars using reverse interlocking. Streamline your system design, reduce infrastructure complexity, and optimize operational expenses with efficient solutions.
Achieve rapid commissioning with simple settings
Leverage integrated functions and simple settings for faster commissioning. Deploy and configure your protection relays quickly to minimize downtime and accelerate project completion.
