Webinar: Avoiding Premature Insulation Failure of Oil-Filled Transformers by Proper Moisture Management

Excessive moisture within the oil and insulating materials of a transformer has a significant effect on the life cycle of these critical and expensive assets. Moisture is one of the most influential elements that can accelerate ageing in oil, paper, and pressboard insulation, possibly resulting in severe damage and premature failure. In this session we will discuss how moisture accumulates, how it effects the aging process, and how significant damage or failure from excessive moisture can occur. We will look at ways to determine the amount of moisture that is present, including the challenges associated with using traditional dissolved gas analysis, (DGA), or oil screens for moisture determination. We will explore more modern techniques such a dielectric frequency response, (DFR).
