Included inputs and outputs
The SIPROTEC 7SL86 includes 12 predefined standard variants with 4/4 or 8/8 current transformers / voltage transformers, 5 to 31 binary inputs and 8 to 46 binary outputs.
Why SIPROTEC 7SL86?
SIPROTEC 7SL86 provides combined line differential and distance protection for overhead lines and cables. Secure your electrical infrastructure and support up to six line ends and 3-pole tripping for reliable power transmission and distribution.
Power grids face challenges from faults, disturbances, transformer errors and current transformer saturation. Our SIPROTEC 7SL86 includes an adaptive differential protection algorithm for high sensitivity and stability, plus multiple distance protection functions for flexible backup.
Configure functions to your needs with the modular design and DIGSI 5 engineering tool. The rapid 9 ms minimum tripping time provides fast fault clearance to reduce downtime.
