Flexible communication and redundancy
Exchange differential protection data via integrated fiber-optic interfaces up to 24 km or two-wire copper cables up to 20 km. Transmit intertripping and 16 binary signals.
Why SIPROTEC 7SD80?
SIPROTEC 7SD80 provides line differential protection for power cables and overhead lines up to 24 km. It offers selective protection for high-voltage and medium-voltage systems across all starpoint configurations, and is well-suited for replacing analog differential protection.
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.
