Predictive maintenance uses DGA, thermal imaging, and trend analysis to catch faults early. GlobeCore supports this with oil testing, regeneration, and online monitoring systems – extending asset life.

In addition to techniques, such as DGA, thermal imaging, and trend analysis, a comprehensive predictive maintenance strategy also involves routine evaluation of oil physicochemical properties and proactive optimization of oil condition. Assessing the factors, including moisture levels, acidity, and particulate contamination, can help you identify early signs of degradation that may not yet appear during electrical or thermal diagnostic evaluation. Integrating the oil treatment and oil reclamation into a maintenance program not only enhances the accuracy of condition assessment, but also reduces the unnecessary downtime of assets and improves the long-term reliability of equipment.

You’re exactly right — oil physicochemical evaluation and active oil conditioning belong at the core of a modern predictive maintenance program because moisture, acidity, particulate contamination and early oil-degradation products often precede thermal or electrical symptoms. In practice that means combining continuous, trend-based online monitoring with periodic lab-style oil tests: dissolved gas and moisture monitoring, dielectric loss (tanδ), breakdown voltage, acid/neutralization checks and particle counts. Using an integrated online system that links condition monitoring to oil-management actions makes it far easier to spot drifting trends, prioritize interventions and avoid unnecessary outages.

To operationalize that approach, pair an online transformer monitoring system for real-time parameter trending with portable and bench oil testers for targeted diagnostics, and have oil-treatment equipment available to act when limits are approached. Continuous monitoring catches fast changes, TOR-style analyzers and breakdown/tanδ testers verify insulation and oil health, and oil-purification, vacuum dehydration and sorbent drying units restore oil dielectric properties and moisture content without long shutdowns. That combination improves accuracy of condition assessment, reduces downtime and extends transformer life by letting you treat oil proactively rather than waiting for a fault.
