Woodward XU1E XU1E Residual Voltage

Woodward 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

Woodward XU1E Residual Voltage : 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.

Interconnection / Mains Decoupling

During mains failures, DER (Distributed Energy Resources) should stay operated and connected to the grid to support decreasing mains voltage, by feeding reactive power. Woodward has developed various Intelligent Electronic Devices, which are in compliance with international grid requirements (Grid Codes), to avoid electrical or mechanical damage to the DER in these cases.

The following product lines offer the right Interconnection / Mains Decoupling products to you.

HIGHPROTEC LINE

The new HighPROTEC line is the latest generation of complete protection for medium-voltage power systems. Learn more about HighPROTEC Interconnection / Mains Decoupling devices:
