“Where Does the Air Go?” by Dave Hanson TJ|H2b Analytical Services, Inc.

Intense investigations have confirmed that traditional procedures may not always prevent air bubbles from entering the transformer tank when the samples are taken, or the monitor is commissioned. Obviously, there is a serious risk of failure when air bubbles enter an energized transformer.

Tap Changer Activity Signature Analysis (TASA®) - Oil/Fluid Analysis

DGA has been applied successfully for many years to non-current switching oil-filled power equipment. The application of dissolved gas analysis to load tap changers (LTC’s) has both similarities and differences to the use of DGA in other oil-filled power equipment. It is similar in that the same processes produce the same gases. However, in terms of gas production, LTC’s are far more complex than transformers. Read more.
