Who Uses Magnefy
Fault prediction applies wherever transformer reliability matters
Any organization that runs oil-filled distribution transformers and bears the cost of unplanned outages has a direct use case. The specifics differ by fleet size, regulatory environment, and operational structure.
Municipal and Co-op Utilities
Replace reactive dispatch with scheduled maintenance
Municipal electric utilities and rural electric cooperatives operate distribution transformer fleets where a single substation outage triggers regulatory reporting, customer notice requirements, and crew dispatch at premium hours. The transformer failure itself is rarely the largest cost item. The downstream cascades are.
Magnefy gives operations teams 3 to 6 weeks of advance notice. That window is enough to order parts from the supplier (not emergency overnight), schedule a maintenance crew during normal working hours, and notify regulators proactively rather than reactively.
A typical distribution fleet has 200-2,000 assets. Magnefy starts with the highest-risk subset and scales to the full fleet after the pilot period confirms detection performance on local equipment.

Industrial Facility Operators
Power reliability as a production constraint
Industrial facilities with continuous processes face a different calculus from utilities. A transformer failure does not just cut power to customers. It stops production, potentially scraps in-process work, and may trigger equipment protection shutdowns that take hours to restart.
For facilities running 24-hour operations, the maintenance window problem is also different. There may be one scheduled production shutdown per quarter. Magnefy's advance warning window is long enough to confirm a fault and schedule the repair into the next planned shutdown rather than forcing an emergency outage.
Facilities typically have between 3 and 50 distribution transformers at varying criticality. Magnefy can prioritize monitoring to the assets whose failure would most directly interrupt production, starting the ROI calculation where the exposure is highest.
Fleet Managers and Asset Owners
Fleet-level visibility across distributed assets
Organizations that own or manage transformer fleets across multiple sites face a coordination problem that per-site monitoring does not solve. A fault developing at one of 80 substations may not surface in any local indicator until it is close to failure.
Magnefy's fleet health dashboard provides a single view across all monitored assets: current health scores, active alerts sorted by severity, and trend data that shows which assets are progressing toward a fault class. Asset managers can filter by location, voltage class, age, or manufacturer to prioritize inspection resources across the fleet.

Results Context
What a 3-6 week warning window is actually worth
The monetary value of an early fault warning depends on how the organization operates and what failure mode is being prevented. We have seen the same 17-day warning produce very different outcomes depending on context.
For a utility with regulatory reporting obligations, the value is partly compliance: a planned repair with a customer notice avoids the regulatory filing that follows an unplanned outage. For a manufacturer running a 24-hour operation, the value is production continuity: scheduling the repair into a planned shutdown avoids losing an entire production day.
