LVDC Power Distribution OCP project

Presenter(s):
JP Buzzell, VP- Data Center Chief Architect, Eaton
Paolo Catapane, Chapter Leader- Solution Product Management Infrastructure, ABB

 The Power Distribution OCP sub-project is running since October 2025 and developing a white paper on Low Voltage Direct Current (LVDC) Distribution for data centers. LVDC eliminates multiple AC/DC conversions- improving efficiency and reducing complexity. The presentation will cover:  
• System Design: system architecture- grid topologies- redundancy levels- and fault domain management
• Voltage and Power Quality: voltage classes- power quality requirements- and regulatory/installation code impacts (NEC and IEC)  
• System Earthing: available options with pros and cons  
• Safety and Protection: protection and safety in Active DC Networks (ADCNs)- including fault-limiting vs. fault-feeding converters- overcurrent protection devices (solid-state CBs)- and ground-fault/electric shock protection
• Key Components: high-level requirements for LVDC distribution components  
• Codes and Standards: current gap analysis and proposed actions
