Field Results
What fault prediction looks like when it works in the field
These are documented outcomes from Magnefy deployments. Customer names are withheld by agreement. Technical details, asset counts, and outcomes are accurate. Full reports are available to qualified prospects under NDA.
Municipal Electric Utility, Pennsylvania
19-day warning prevents substation outage during winter peak demand
A municipal electric utility in western Pennsylvania enrolled 20 distribution transformers in the Magnefy pilot during Q3 2025. The fleet ranged from 14 to 31 years old, with three assets that operations had flagged as "watch" status based on conventional oil analysis from the prior year.
On day 47 of the pilot, Magnefy flagged a winding insulation fault developing on a 25-year-old 2,500 kVA unit at a substation serving a residential district. The alert classified the fault as insulation degradation, severity caution, predicted event window 14-21 days. Confidence: 91%.
The operations team verified the alert against a supplemental oil sample, which showed elevated 2-furfuraldehyde consistent with advanced cellulose degradation. The transformer was scheduled for offline inspection in week 3 of the alert. The inspection confirmed the fault. A replacement unit was installed before the January heating season began.
Cement Manufacturing Facility, Ohio
Cooling system fault detected and repaired during scheduled shutdown, avoiding production stoppage
A cement plant operating three kilns continuously monitored four distribution transformers with Magnefy starting Q4 2025. Two of the transformers supply power to kiln motor loads directly; the other two feed auxiliary equipment. The plant runs 24/7 with one planned 5-day maintenance shutdown per quarter.
On day 31 of monitoring, Magnefy detected a thermal load curve deviation on the primary kiln feed transformer. The pattern matched the cooling system fault signature: the relationship between load and the thermal component of the EM signature had shifted in a way consistent with reduced radiator airflow. Severity: watch. Predicted progression to caution: 10-18 days.
The maintenance team inspected the radiator bank and found two of four cooling fans had failed bearing mounts. Both fan motors were replaced during the next scheduled maintenance day, 16 days after the initial Magnefy alert. The transformer returned to normal thermal signature within 48 hours of the repair.
On Our Results Reporting
What we report and what we do not
We do not publish aggregate detection statistics across all deployments because the fleet characteristics, asset age, and operating conditions vary enough that a single accuracy number would be misleading. What we report is documented outcomes from specific deployments, with enough technical context to evaluate the claim.
Full pilot reports for both case studies above are available to qualified prospects. The reports include the raw alert logs, confirmation methodology, asset metadata, and the timeline from first alert to physical confirmation. We do not redact the inconvenient entries.
If you want to speak with the operations teams directly, we can make introductions in select cases. Ask during the demo conversation.
