As a transformer ages, its risks of failure rise and its inherent reliability deteriorates. Possible consequences of an unexpected failure of a business-critical transformer can be uncontrolled financial costs / lower profit due to loss of production and business interruption. Additional consequences can be reduced asset life and loss of life. Regular oil analysis provides an insight into the “health” status of a transformer and a low-cost means of tracking a fault. When combined with other electrical tests and sound engineering knowledge, oil analysis can provide a very powerful tool to diagnose and assess the condition of each unit.
This webinar explores the use of dissolved gas analysis (DGA) to identify advancing failure modes in a power transformer. Our transformer specialists will then detail electrical test and inspection strategies that can be applied to identify the assets true underlying condition and comprehensively assess the severity of an existing problem. This information is essential to help an asset manager understand what corrective actions can be taken to reduce the risk of failure. The webinar will include several instructive case studies.
