Siemens / Sensitive ground fault detection _ Setting & highlights _ SI5033

Table of Contents

Overview

The “Directional sensitive ground fault detection” function (ANSI 67Ns) serves for directional detection of permanent ground faults in isolated or resonant-grounded systems, directional detection of fast extinguishing transient ground faults in isolated or resonant-grounded systems, determination of the faulty phase, and detection of high-impedance ground faults in effectively (solidly) or low-impedance (semi-solidly) grounded systems.

The “Non-directional sensitive ground fault detection” function (ANSI 51Ns) serves for ground-fault detection in isolated or resonant-grounded systems, and for detection of high-impedance ground faults in effectively (solidly) or low-impedance (semi-solidly) grounded systems.

For more detailed information on “Sensitive ground fault Detection” functions, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
