Claims
- 1. An apparatus for automatically analyzing gases in oil comprising:
- a gas extractor for deriving a slight amount of oil from an oil-immersed equipment to extract combustible gases contained therein in accordance with a sampling rate;
- a gas analyzer for deriving the combustible gases extracted by the gas extractor to analyze the total quantity of the combustible gases or quantities of specified combustible gases; and
- a data processor for storing results analyzed by the gas analyzer, for determining the trend of combustible gas quantities exceeding a predetermined value in the sample oil and the presence or absence of an abnormality in the oil-immersing equipment thereby, for compensating for errors in the results of the gas analyzer by performing statistical processing in which dispersion of data is considered, and for automatically adjusting the sampling rate of oil sampling and analytical processing routines on the basis of an increasing or decreasing trend of the analyzed results.
