Grounded in safety. Engineered for stability.
Minera E earthing transformers create a defined neutral point and control earth-fault currents — delivering safe, stable grounding for medium-voltage networks up to 72.5 kV.
Explore MoreWhen earth faults disrupt systems.
Medium-voltage networks without controlled grounding face high earth-fault currents, unstable neutral conditions, and stress on protection systems. Conventional solutions struggle to ensure predictable and safe fault behavior.
Meet Minera E — stabilised grounding for MV networks.
Minera E is a purpose-built earthing transformer designed to create a reliable neutral point in medium-voltage systems. By limiting earth-fault current to safe, predefined levels, Minera E enhances protection selectivity, improves system stability, and supports safer fault management across complex electrical networks.
