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...

TRANSFORMER INRUSH

ABSTRACT
Here we discuss the phenomenon of transformer inrush; what it is and its significance to transformer protection design.

INTRODUCTION
A couple of years ago in this Transformer Special Edition, we wrote an article that covered the most used transformer protection schemes. As was pointed out in that article, protective systems have two jobs. They must detect conditions that endanger personnel and equipment, But they must also allow the normal and expected power system and...
