Reference Design 101: Tri-Redundant Electrical Distribution for OCP Data Centres

This document details a scalable, tri-redundant electrical distribution architecture for large data centres using Open Compute (OCP) style racks, designed for internet giants with IT fault tolerance. It outlines a 56.16 MW IEC-compliant facility built in 9.36 MW increments, featuring prefabricated HV/MV substations, dual power paths, and N+1 cooling to reduce CapEx, OpEx, and time to market.
