High-speed tripping
Achieve rapid tripping for critical events. Use impedance settings for precise protection of short lines. Prevent non-selective tripping with the current transformer saturation detector for system stability and reliability.
Why SIPROTEC 7SA64?
The SIPROTEC 7SA6 distance protection relay is a universal solution for protection, control and automation. It operates across all voltage levels, providing comprehensive system management.
Benefit from high-speed tripping times for rapid fault isolation and an impedance setting range that protects even very short lines. The current transformer saturation detector prevents non-selective tripping, enhancing system reliability and selectivity.
Note: this product is in the process of being phased out.
