Advancements in Dissolved Gas Analysis: Risk Assessment

In general, the purpose of periodic screening with DGA for power transformers is risk assessment. Is any transformer likely to fail in service? If so, how severe is the problem? Previous articles in this series have described ways to improve DGA interpretation. In this article we provide a glimpse...

Designing A Safe & Reliable Transformer Maintenance Program

The critical importance of power to every aspect of our world cannot be over-exaggerated. It must be generated and distributed effectively to end users, and any disruption in that process means loss of operations, money, and in extreme cases, life. Therefore, the reliability of power creation and...

Smart Transformers

Maximizing continuous and reliable power output, extending the life of a power transformer, and reducing maintenance costs are just a few of the benefits motivating electric utilities to move toward buying a “smart transformer”, electrical equipment integrated with Smart Grid-enabling software systems.

Smart transformers combine current competitive technology with data acquisition for monitoring power transformer critical parameters, ultimately maximizing employees’ productivity while minimizing expenses. Additionally, smart transformers integrated into Smart Grid-enabling software systems can...
