Case Studies

Data Center Expansion – Denver, Colorado, USA

During a major capacity upgrade, our testing team discovered compromised insulation in a dry-type transformer using DGA and IR testing. Immediate replacement prevented what could have been a catastrophic failure under load, preserving over $2 million in critical equipment.

Energy Storage Hub – Phoenix, Arizona, USA

An energy storage provider experienced inconsistent relay tripping. Our secondary injection and timing tests uncovered calibration drift in protective relays inside medium-voltage switchgear. Adjustments restored system coordination and eliminated nuisance trips.

Provincial Research Lab – Vancouver, British Columbia, Canada

A transformer in a high-availability power lab showed phase imbalance during routine inspections. Using SFRA and TTR analysis, we identified internal winding deformation. The client avoided an unplanned shutdown and secured grant funding by demonstrating proactive asset management.
