Overview
Data centers depend on electrical systems that must deliver clean, continuous power to IT equipment even when the utility fails, equipment breaks or maintenance is under way. From medium voltage incomers and transformers to generators, uninterruptible power supplies, switchboards, busways and rack power distribution, every part of the chain must be designed for resilience and safety. As AI deployments push power densities and facility capacities to new levels, electrical design decisions now have an even greater effect on cost, speed of delivery and the ability to expand without disruption.
This course provides an engineering view of electrical power systems for mission-critical facilities. Participants learn how power flows from the utility connection to the server, how redundancy topologies are built, and how to size the main components of the electrical infrastructure. The course covers medium and low voltage distribution, transformers, standby generation, UPS technologies and energy storage, static transfer switches, busway and rack power distribution, grounding, power quality and protection coordination. It also explains arc flash safety, maintenance strategies, monitoring with electrical power management systems, and the electrical implications of high-density AI loads and fast load changes.
Objectives
- Trace the power path from utility connection to the server power supply
- Compare redundancy topologies and their effect on availability and cost
- Size transformers, generators, UPS systems and distribution equipment
- Select UPS technologies and energy storage for mission-critical loads
- Apply grounding, power quality and protection coordination principles
- Plan safe operation and maintenance, including arc flash risk management
- Assess the electrical impact of high-density AI loads and fast load changes
Who should attend
Electrical engineers, power system designers, consultants, commissioning engineers and critical facility electrical leads.
Training methodology
The course combines engineering principles with single line diagram reviews, sizing calculations and failure scenario analysis. Participants trace power paths on sample diagrams, compare redundancy topologies, size generators and UPS systems for a defined facility, and examine protection coordination studies and arc flash labels. Failure mode exercises test how each topology behaves during utility loss, component failure and maintenance. Case studies of outages in operating data centers show how design and operational decisions combine. Each day ends with a short design review and quiz.
