• 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.
