Normalized energy intensity (NEI), a fault energy index based on the standard heats of formation of fault gases, provides a useful way to look at fault severity. Check out this short article by Dr. Zachary Draper and Dr. Jim Dukarm from Electricity Today Magazine on how NEI can be used to assess and track faults… Continue reading →

Gas loss within a transformer can hide serious problems for dissolved gas analysis results. Check out this short article by Dr. Zachary Draper and Dr. Jim Dukarm from the High Voltage Electrical Testing special edition of Electricity Today Magazine on how gas loss can be taken into consideration in dissolved gas analysis interpretation to improve… Continue reading →

Join Dr. Jim Dukarm as he describes how physical chemistry and advanced statistics are breathing new life into transformer DGA. This article describes important advances like the use of fault energy indices and reliability statistics, and also provides an example that shows how these advances can improve fault detection and provide new risk assessment information.

Find out how a major US utility is already using Reliability-based DGA to help identify and focus on at-risk transformers so they can implement an effective strategy to maintain and replace them as needed.
