Intelligent power management leader Eaton has achieved an industry-first solution that identifies large fluctuations in energy consumption caused by artificial intelligence (AI) computing infrastructure, commonly referred to as AI power bursts. The company introduced this innovation through a firmware update for its Eaton Power Xpert quality (PXQ) event analysis system, enabling edge-based detection of potential subsynchronous oscillations (SSO) in data centers. This development helps operators better safeguard critical infrastructure and enhance resilience as AI workloads continue to surge.
As AI data centers demand increasing amounts of power, they face the phenomenon of power bursting sudden, unexpected spikes in energy usage driven by the intensive computation of GPU servers handling AI workloads. Such bursts can generate SSO, which may damage both data center systems and the broader electrical grid if left unchecked. Potential consequences include transformer overheating, ferroresonant damage, and costly equipment failures. Consequently, early detection and mitigation of SSO bursts are crucial to prevent outages and operational disruptions.

Eaton’s PXQ meter, designed for switchgear, switchboards, and power distribution units (PDUs), integrates advanced edge analytics to identify and resolve power quality events such as sags, swells, transients, and harmonics. With the latest remote firmware upgrade, PXQ users can now reliably detect SSO events and take proactive measures to prevent lasting damage to data centers and the grid.
“The energy demands of AI workloads surpass anything data centers and the grid have encountered before, with load fluctuations that can exceed the limits of existing infrastructure,” said JP Buzzell, vice president and chief data center architect at Eaton. “By enabling customers to harness their existing PXQ technology in new ways, we’re delivering a market-first capability to effectively respond to AI power bursts. Our SSO detection solution marks a major milestone in our grid-to-chip strategy, which empowers data center operators with innovative tools to address and manage the energy challenges posed by AI.”

Eaton’s grid-to-chip strategy combines intelligent power distribution systems, backup power solutions, and digital tools to help operators optimize both white and gray space in AI data centers. Recent milestones include a collaboration with NVIDIA to advance 800 VDC power infrastructure for 1-megawatt racks and a partnership with Siemens Energy to accelerate the construction of data centers with integrated onsite power.
Eaton will demonstrate its grid-to-chip solutions at Yotta 2025, September 8–10, in Las Vegas. Experts JP Buzzell and Peter De Bock, vice president of energy and cooling, will also present sessions addressing strategies for meeting AI data center energy challenges in today’s evolving landscape.
Dedicated to intelligent power management, Eaton aims to protect the environment and improve quality of life globally. Through innovations in electrification and digitalization, the company continues to solve pressing power management challenges while building a sustainable future for generations to come.
