Siemens / Directional overcurrent protection ground (ANSI 67N) _ Setting & highlights _ SI5078

Overview

The “Directional overcurrent protection ground” function detects short circuits to ground affecting electric equipment. It ensures selective ground-fault detection for parallel lines or transformers with infeed at one end, and also selective ground-fault detection in cable runs with infeed at both ends or in lines connected to form ring topologies.

For more detailed information on “Directional overcurrent protection ground” function, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
