Timing and modality to obtain representative and beneficial DGA sample for liquid-filled device
Marius Grisaru
Sažetak
The literature and most of the offline and online seminars on DGA deeply and extensively elaborate on the DGA diagnosis and some DGA separation and measurements novelties. Sampling aspects can
mainly be found on short videos on You-Tube, released by major companies. This trend is probably responsible for attributing an image of low-tech and low importance to sampling procedures in comparison with the sophisticated and high-tech stage of diagnosis. On the contrary, the sampling phase combined with vessel selection and packaging for transport is the most deciding step for an accurate and valuable transformer diagnosis by DGA. This column is inspired by three sessions presented at Transformers Academy, dealing with DGA sampling: when to sample, how to sample, which
vessels to use for DGA sampling and some suggestions for an economical and precise sampling procedure.
