Power transformers are some of the most expensive and hardest-to-replace assets in a utility’s network, and when one fails without warning, the damage spreads well beyond the equipment itself. Most failures develop over months, giving off thermal warning signs that periodic manual inspections can easily miss. Systems With Intelligence’s Touchless™ online transformer monitoring puts continuous, real-time visibility on bushings, connections, and cooling systems, so your team can catch faults early and plan maintenance on its own schedule.
Advanced Transformer Monitoring Solutions That Catch Faults Before They Fail
Power transformers are some of the most expensive and hardest-to-replace assets in a utility’s network. Many have been in service for decades, and replacing one can take months of lead time. When a transformer fails without warning, the damage goes well beyond the equipment itself. Outages spread across the grid, crews get pulled into emergency response, and the public feels it.
Systems With Intelligence‘s Touchless™ online transformer monitoring gives utility operators and asset managers continuous, real-time visibility into transformer health, from bushings and connections to cooling systems. Our utility-grade thermal and visual monitoring delivers early fault detection, so your team can plan maintenance on its own schedule rather than react to unexpected failures.
What You Can Monitor
SWI tracks the critical parameters that reveal a transformer’s true condition, giving operators a complete view of each asset in real time.
- Transformer Bushings: Bushings are among the most common points of transformer failure. Continuous thermal monitoring detects overheating connections, phase imbalances, and the localized heating that can accompany insulation breakdown.
- Main Tank & Transformer Oil Temperature: Monitoring the transformer body and oil level indicators helps identify abnormal heating patterns in the transformer oil and supports overall asset health assessment.
- Cooling Systems: Radiators, fans, and pumps that stop working properly show up as uneven thermal patterns. Early visibility into cooling performance supports better cooling control decisions and helps prevent the transformer from running too hot under load.
- Load Tap Changers: Thermal monitoring of an external load tap changer helps flag developing contact and connection problems.
- Connections & Surge Arrestors: High-voltage connections, switches, and nearby surge arrestors are monitored within the same field of view, giving a fuller picture of the transformer bay.
From Scheduled Inspections to Predictive Maintenance
Continuous transformer monitoring gives your team the data to move from fixed-interval inspections to condition-based and predictive maintenance. Instead of sending crews to check every asset on a calendar, you can focus resources on the transformers that actually need attention.
For utilities managing dozens or hundreds of transformers, SWI’s data-driven solutions support fleet management at scale. Asset managers can compare health trends across sites, prioritize capital spending, and make replacement decisions based on real condition data rather than age alone.
Benefits at a Glance:
- Risk reduction: Lower the likelihood of unplanned outages and catastrophic transformer failure
- Extend asset life: Catch problems early to get more years from high-value assets
- Lower inspection and truck-roll costs
- Improve operational safety by keeping personnel out of hazardous, energized areas
- Make faster, data-backed maintenance decisions across your entire fleet
