Gas in oil analysis, high acetylene, how dangerous?
(OP)
Just received a dissolved gas in oil analysis on a 2000 kVA 25kV/480V three phase transformer. Acetylene is 102 ppm and total combustible gas is 212 ppm. Having another sample pulled tomorrow. How dangerous a transformer do I have? Should it be de-energized immediately? From what I have been reading on the internet, this looks real bad. Anyone with any experience with a transformer with that high an acetylene level?

Marmite above has very excellent points to take into account. Any past dga's on this bank? Check the pattern.
Still if you check IEEE dga guideline for DGA that bank is deteriorating/failing as we speak.

We have had gases show up apparently due to small amounts of LTC oil leaking past barrier board into the main tank.

Some time ago we had people injured in an explosion and fire due to the accumulated combustible gas in a de-energized xfmr while preparing it for shipping to be sent out for repair. Luckily there were no serious injuries, just some dirty underwear. But this issue is not to be taken lightly….
