what is the optim interval for the fuzzification of IEEE and ICE limits.

Thank you for your answer. I think that is very hard to 'talk' with a person who don't know English for have a confirmation of a hot point ther is another metod then termovision how can I have the confitmation of a arcing

My enhlish is very poor I know very good how fault gases apear. I refer to other measurements

I will be more clearly - for celulose decomposition: I measure H2O content, acidity ...... can you tell me what must to measure for arcing; overheating; PD.

if a DGA analyse indicate a fault (partial discharge, overheating, arcing, celulose) witch are the measurements I can do to have a confirmation of this fault)?

Is posible to have a high concentration of C2H2 (70-90)and almost zero H2 concentration?

Here are two almost same standards http://ieee.org/ (IEEE Std C57.104-1991) http://www.iec.ch/ (IEC 599)

Your transforme can have a local overheating. Try to view the generation rate (some new transformers can have some hidrocarbon gases from manufacturing but usualy not ethan). Resample and view the genration rate.

Yes is a good idea to see the moisture content and the acidity level, the CO2 increase look like accelerate celulose aging because a celulose overheating is folow by CO increase. Tray to see the CO content and it is biger that 300-350 ppm do CO2/CO ratio, if it is lower that 3 and biger that 10...
