## Advanced Digital Substation Architecture

The substation operates at 400 kV and 132 kV voltage levels and connects 4 autotransformers using digital process bus communications.

Advanced fibre-optic relay networks provide sub-cycle differential protection and instantaneous fault isolation across all outgoing feeder bays.

## Supporting Clean Energy Grid Targets

The substation supports the Dubai Clean Energy Strategy with 100% digital protection redundancy across the central transmission corridors.

High-capacity power transformers ensure efficient voltage step-up and stable dispatch into the emirate bulk supply grid.
