Why SIPROTEC 7SA86?
SIPROTEC 7SA86 distance protection is a modular device for protecting electrical lines. It offers an advanced solution for protection, control, automation, monitoring and power quality basic functions, powered by DIGSI 5. Address short circuits and ground faults in electrical systems with the SIPROTEC 7SA86. It detects and selectively trips 3-pole short circuits across all voltage levels and network configurations, including ground faults, to provide reliable backup protection for various differential protection devices with a minimum tripping time of 9 ms. Expect reliability with powerful protection functions, advanced cybersecurity features, and high availability even in extreme conditions through conformal coating. Configure all functions with DIGSI 5, adapting the flexible I/O structure to your needs.
