As generative AI workloads explode, so does the pressure on electrical systems in data centers. But many operators are blind to the very power anomalies threatening their uptime. The truth? Most faults don't happen out of nowhere—they build up. And if you're relying on traditional monitoring tools, chances are you're not catching them until it's too late. Here are the top 5 power anomalies costing AI data centers millions in downtime, degraded SLAs, and missed capacity opportunities:
⚠️ 1. Voltage Imbalances
AI clusters often have asymmetric loading due to uneven server draw, creating voltage imbalances that slowly degrade transformer performance. Over time, this leads to overheating and reduced lifespan—or worse, catastrophic failure with no prior alarm.
❌ Traditional FDD: Often misses imbalances below a threshold or treats them as non-critical.
✅ Verdigris: Continuously monitors phase-level data and flags asymmetry trends before they reach critical levels.
⚠️ 2. Breaker Overloads
In high-density racks, breakers can get pushed to their limits by microbursts of power draw—especially during AI training workloads. These transients are often shorter than the logging interval of most BMS or DCIM tools.
❌ Traditional FDD: Logs at 1-minute intervals—far too slow to capture transients.
✅ Verdigris: Sub-minutely, circuit-level data catches momentary spikes and cumulative stress.
⚠️ 3. Harmonic Distortion
Variable power loads from GPU-heavy AI clusters introduce harmonic distortion, which can disrupt sensitive electronics, trigger false alarms, or cause overheating in neutral conductors and transformers.
❌ Traditional FDD: Lacks the resolution or depth to track harmonics over time.
✅ Verdigris: Detects harmonic profiles and surfaces historical trends for root-cause analysis.
⚠️ 4. Nuisance Tripping
Rapid current changes can trigger nuisance breaker trips that appear random—until they happen during a critical compute job, wiping out uptime guarantees.
❌ Traditional FDD: Can't correlate the event back to cause—often attributed to “bad luck.”
✅ Verdigris: Tracks real-time loading patterns and correlates event sequences to pinpoint contributing circuits.
⚠️ 5. Hidden Intermittent Faults
Some faults don’t happen once—they keep happening, quietly. A hot lug, loose neutral, or degrading insulation can cause intermittent issues that escape detection but slowly erode reliability.
❌ Traditional FDD: Event-driven only—no persistent insight.
✅ Verdigris: Combines high-frequency data with retrospective analysis to identify recurring signatures over time.The Bottom Line:
AI workloads are too dynamic—and too critical—to trust to legacy tools. If your current system can't catch these anomalies, you're not just at risk of downtime… you're already behind.
