The XI1-S of the PROFESSIONAL LINE is an all-purpose protection against earth faults, used for electrical machines, lines and networks with solidly earthed or resistance-earthed neutral; it is mainly used in radial networks. Very often the XI1-S can be found as backup protection at the central earthing point of the system. It detects all earth faults occuring in the system. In this case the trip delay selected must exceed the longest time delay setting of any other earthing protection used in the system.
