Overview
AI training runs are unforgiving of power events: a multi-week job lost to a transient is far more expensive than the maintenance that would have prevented it. This product covers the whole distribution chain — incoming feed, switchgear, UPS plant, PDU, busway and the rack-level receptacle — with load banking and thermal imaging to catch degradation that normal inspection misses.
What is covered
- UPS plant: battery string impedance testing, capacitor inspection, fan and filter service, firmware currency review
- Generator and transfer switch exercise under load, with fuel quality sampling and polishing schedule
- Infrared thermography of switchgear, busbar joints, lugs and PDU terminations under representative load
- Load balancing across phases and circuits, with headroom analysis against planned accelerator additions
- PDU and busway inspection, torque verification, and receptacle wear assessment
- Power quality logging: harmonic distortion, voltage sag and swell, transient capture
- Earthing and bonding verification
Deliverables
- Single-line diagram annotated with as-found condition and measured loads
- Thermographic survey report with severity-ranked findings and photographic evidence
- Battery and capacitor replacement forecast with costed lead times
- Capacity headroom statement: what the facility can support today, and what constrains the next rack
Who this is for
Sites where a power transient would abort long-running training jobs, and where rack density is climbing faster than the original electrical design anticipated.
