• XU1-E

    The XU1-E of the PROFESSIONAL LINE is a digital relay for earth fault detection in isolated and resistively earthed medium voltage systems. Digital filters ensure a suppression of harmonics.
    The relay can be connected to the open e-n winding of the voltage transformer.

    Unit XU1-E has a single step earth fault voltage supervision. The noise signals caused by inductive and capacitive coupling are supressed by an analog RC filter circuit.

  • XP2-R-5

    Relay XP2-R of the PROFESSIONAL LINE is a digital relay for reverse power detection of gensets in parallel and active power supervision of power systems.

    For generators operating in parallel with a mains or another generator, it is imperative to supervise the power direction. If for example the prime mover fails the alternator operates as a motor and drives the prime mover (diesel or turbine). The XP2-R detects the reverse of the power direction and in case of this error switches off the alternator. This way, power losses and damages of the prime mover are avoided.

  • XI1-S-1

    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.
