WOODWARD XD1G11 Differential Protection Relay

Description
The WOODWARD XD1G11 is a differential protection relay designed for line protection up to 1500 meters, utilizing summation current transformers to combine three-phase currents into a single-phase signal for fault detection.

Features
Uses summation C.T. type XD1-GW135 for three-phase current combination.
Requires only two auxiliary wires for signal supervision.
Built-in pilot wire monitoring detects breaks or supply failures and blocks tripping.
Complies with international standards including IEC 255 and VDE 0435.
