Modern data centers rely on highly stable, high-quality power to support increasingly dense IT loads, complex cooling systems, and mission-critical operations. As AI, automation, and digital services drive rapid growth, power quality issues such as harmonics, reactive power imbalance, voltage instability, and fluctuating loads pose growing risks to reliability, efficiency, and sustainability. This brochure outlines Hitachi Energy’s power quality product portfolio for data center power networks and auxiliaries, spanning low-, medium-, and high-voltage environments. It examines common sources of power quality challenges across IT, cooling, and auxiliary systems, and presents practical solutions—including capacitor banks, active harmonic filters, STATCOMs, and hybrid architectures—to improve power factor, reduce losses, enhance grid compliance, and protect critical infrastructure. The portfolio is designed to support resilient, scalable, and energy-efficient data center operations from grid connection to rack-level distribution.
