The 99.999% Challenge
Modern hyperscale data centres demand power availability of 99.999% — that's less than 5.26 minutes of downtime per year. Achieving this requires not just redundant systems, but the right transformer technology at every level of the power distribution chain.
Transformer Selection Criteria
For data centre applications, transformer selection goes beyond standard specifications:
Efficiency: With continuous 24/7 loading, even small efficiency gains compound into significant energy savings. Our amorphous core distribution transformers achieve no-load losses 70% lower than conventional CRGO cores.
Thermal Performance: Data centres generate enormous heat loads. Our transformers are designed for AN/AF cooling with smart thermal monitoring, ensuring stable operation at ambient temperatures up to 50°C.
Compact Footprint: Floor space in data centres costs $2,000–$5,000 per square metre. Our cast resin dry-type transformers eliminate the need for fire suppression rooms and oil containment, reducing the total installation footprint by up to 40%.
Redundancy Architecture
We engineer transformer solutions for all major redundancy configurations:
- N+1: Single redundant unit per group
- 2N: Fully duplicated power paths
- 2N+1: Maximum resilience with additional backup
Smart Monitoring Integration
Every transformer we supply for data centre applications includes provisions for IoT-enabled condition monitoring — dissolved gas analysis (for liquid types), winding temperature, load current, and harmonic distortion.
Proven Track Record
ETS has supplied transformer solutions for over 120 data centre projects across the Middle East, Africa, and North America, including facilities for leading cloud service providers.
