Impact of switchgear on attaining energy efficiency in data centres
As the digital revolution continues, embracing automation in data centres is a significant cost-saving opportunity.

In our digital age, data centres are the backbone of our always-on world. However, these facilities consume vast amounts of energy, accounting for about 1% of global greenhouse gas emissions. With data centre energy demand expected to surge by 160% by 2030, the need for energy-efficient solutions is more pressing than ever.
Switchgear, the unsung hero of power distribution, plays a crucial role in enhancing energy efficiency in data centres. Modern switchgear technologies offer significant advantages over traditional systems:
1. CT/VT Sensors: These reduce energy consumption compared to conventional transformers, resulting in substantial savings.
2. Digital Switchgear: By combining proven technologies with digital components and software solutions, digital switchgear enhances safety and reduces energy costs by up to 30%.
3. SF6-Free Switchgear: This sustainable alternative minimises greenhouse gas emissions while maintaining high performance. For instance, using current/voltage sensors instead of conventional transformers in medium-voltage air-insulated switchgear can save 150 tonnes of CO2 over a typical 15-panel board’s service life.
4. Centralised Protection Systems: These user-friendly systems allow control of an entire substation from a single device, improving efficiency.
5. Monitoring and Diagnostics: Integrated systems provide predictive analytics on switchgear health, preventing potential downtime.
Digitalisation is key to achieving sustainability goals in data centres. Digital switchgear features multiple sensors that measure parameters like temperature and humidity, helping to monitor facility health and predict potential failures. This proactive approach avoids costly downtime and unnecessary maintenance.
Reliability is another crucial factor in reducing a data centre’s carbon footprint. By addressing issues such as power conditions, cooling, and equipment failure, reliable systems ensure consistent performance and energy efficiency.
Uninterruptible Power Supply (UPS) systems are also vital for data centre efficiency. Advances in UPS power electronics focus on improving efficiency across various loading levels. When a UPS operates at 240/415V with a three-phase four-wire output, power can be fed directly into servers, reducing facility energy consumption by an additional 2%.
