Success Stories

Transformer Failure Investigation

Conducted comprehensive forensic analysis of a failed 138/13.8kV power transformer at a critical industrial facility that experienced a catastrophic failure.

Results:

Identified manufacturing defect in tap changer mechanism that caused internal arcing. Analysis led to inspection of similar units across client's system, preventing three potential similar failures and saving an estimated $2.3 million in downtime costs.

Distribution System Fault Pattern Analysis

Performed detailed investigation of recurring momentary faults on rural distribution circuit experiencing frequent customer interruptions despite multiple traditional inspection patrols.

Results:

Utilizing advanced pattern analysis, identified unmarked irrigation equipment operation as the root cause. Implementation of specialized coordination settings reduced momentary interruptions by 78% and improved circuit reliability indices by 65%.
