Differential Relay Type A for Transformer Circutor WGC RGU-10A

The RGU-10A is a highly immune type A differential current protection and monitoring relay, compatible with the WGC range of differential transformers.

The device measures, calculates, and displays the differential current in true RMS value, through a differential current input, sourced from an external toroidal measuring transformer from the WGC series.

The RGU-10A allows for the programming and adjustment of all parameters required to achieve complete protection and control of the installation. 

Main features:

• True RMS measurement.
• RCM & MRCD in the same device.
• Menu programming lock via keypad.
• RGB backlit display.
• Ultra-immune type A differential.
• Immunity to transients.
• Filtering of higher order high frequencies.
• Trip adjustment between 80 and 100% IΔn.
• Inverse curve

Applications

The RGU-10A enables intelligent differential protection.

Its design features ensure the most comprehensive type A protection to guarantee the safety of individuals and ensure continuity of supply in electrical installations.

Its ultra-immune system ensures that a trip will only occur when absolutely necessary, avoiding economic losses due to unwanted trips.

Being able to view the instantaneous leakage value on the display, along with pre-alarm indications, provides information about the status of the lines being protected, allowing for effective preventive maintenance.
