Designed to establish a neutral grounding point in three-phase electrical networks, the Earthing Transformer provides a controlled path for earth fault current in systems without an accessible neutral. Its zigzag winding configuration and application-specific short-time current capability support effective grounding, protection coordination, and reliable operation in medium-voltage distribution networks.
