XU1E
XU1E Residual Voltage

Residual Voltage Protection - Detection of Earth Faults in isolated or high ohmic grids. Basic time delay accuracy = 0.5 % or ±25 ms. Accuracy of the specific rated values: 1 % at nominal frequency

FEATURES & FUNCTIONALITY

The relay XU1E of the easy 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.

The XU1E is compliant with IEC 60255-1.
