Control and prevent moisture presence. Regularly
Smart moisture management with our Moisture Care solution
Power transformers depend on the proven reliability of paper and oil insulation. While no modern alternative has surpassed this system, its performance and longevity are highly sensitive to moisture. Managing moisture is essential to avoid insulation degradation and transformer failure.
Moisture: A silent threat
Moisture silently compromises transformer health by degrading both oil and cellulose insulation. To prevent external moisture ingress, dehydrating breathers with hygroscopic salts are commonly used.
Choose our advanced Self-Dehydrating Breather (eSDB)
Whether you are managing asset health remotely or on-site, our eSDB breathers provide continuous protection.
Your transformer will be continuously protected from moisture intake, and you can collect the necessary data online for remote transformer health management.
Internal moisture sources
Moisture doesn’t only come from outside. As paper insulation ages—especially under heat—it decomposes and releases water. Even sealed transformers can accumulate internal moisture over time. Thus, moisture management must address both external ingress and internal generation.
Traditional methods, such as oil sampling and Dissolved Gas Analysis (DGA), offer only periodic insights into the moisture content of the oil insulation.
Choose our Oil diagnostic device type eDOC. Measure the presence of moisture and hydrogen inside the transformer oil continuously and make informed decisions about the asset maintenance needs (link)
Data driven maintenance
The true value of continuous monitoring lies in the historical data trends it generates. These trends reveal patterns and anomalies that individual data points cannot show. With consistent, real-time data, operators can extend the life of transformers and reduce risk.
MeDICA, our Monitoring ecosystem for transformer Diagnostics with Integrated Customer services and Analytics.
MeDICA integrates online monitoring and offline testing to support a sustainable maintenance strategy. It combines diagnostics, analytics, and customer services to ensure long-term transformer health.
Moisture care: A complete solution
Moisture is inevitable, but its impact can be managed. With the right tools and services, you can protect your transformers, optimize their performance, and secure your investment.
