Controlling Oil Sampling for Reliable DGA: Eliminating Risk, Improving Repeatability, and Reducing Cost

Accurate DGA depends entirely on the integrity of the oil sample. Traditional sampling methods introduce significant risks through cross contamination, inconsistent connections, and operator variability. This article explores how controlling the sampling process is just as important as the analysis itself.

The Impact of Cross Contamination on DGA Interpretation: Small ppm Changes, Big Diagnostic Consequences

DGA is an exceptionally sensitive diagnostic technique where even small ppm variations caused by cross contamination can significantly influence interpretation, alter fault classification, and undermine confidence in asset condition assessments.

Dissolved Gas Analysis (DGA) and the Importance of Sample Integrity: Eliminating Cross Contamination with Trans-Sample Couplings

DGA is one of the most powerful diagnostic tools for assessing the internal condition of oil-filled electrical equipment. However, its effectiveness depends entirely on sample quality and repeatability. This article explores how cross contamination compromises DGA accuracy and how Trans-Sample dedicated oil sample couplings eliminate this risk by providing a sealed, repeatable, and asset-specific sampling interface.
