Data Center Power Solutions
Reliable power infrastructure for mission-critical facilities
Key Power Challenges
High Density
Modern AI/ML workloads require 10-20kW per rack. Traditional designs assumed 2-5kW.
Redundancy
N+1 minimum, preferably 2N. Single points of failure are unacceptable.
Cooling Integration
Power and cooling are interlinked. Plan electrical to support cooling infrastructure.
Fire Safety
Enclosed spaces require fire-safe equipment. Dry-type preferred over oil-filled.
Low Noise
Transformers in or near occupied areas. Target <55dB noise level.
Scalability
Design for future growth. Plan capacity headroom of 20-40%.

Frequently Asked Questions
Q: What power requirements do data centers have?
Data centers require N+1 or 2N redundancy, 24/7 operation, low noise, and fire-safe equipment. Power density ranges from 2kW to 20kW per rack.
Q: Why choose dry-type transformers for data centers?
Dry-type transformers are fire-safe, emit no toxic smoke, and don't contain flammable liquids. Essential for enclosed spaces occupied by personnel.
Q: What redundancy level is recommended?
N+1 minimum for Tier III, 2N for Tier IV facilities. This ensures zero downtime during maintenance or single component failure.
Q: How do you calculate transformer sizing?
Start with total rack load + 20% growth margin + 10% cooling overhead. Also account for UPS efficiency losses (92-96%).
Q: What about renewable energy integration?
Solar/battery integration is increasingly common. Ensure transformer rated for bi-directional power flow and proper grid interconnection.
