  • Patent number: 9003865
    Abstract: An in-oil gas concentration measuring system comprises: gas extracting which extracts an in-oil gas from an insulating oil sample; component detecting which detects gas components of the in-oil gas extracted by the gas extracting; extracted-gas concentration calculating which calculates, on the basis of data detected by the component detecting, extracted-gas concentrations of the gas components being detected; extracted-gas concentration storing which stores information on the extracted-gas concentrations calculated by the extracted-gas concentration calculating as a result of two or more extractions performed by the gas extracting, the information being stored in each of the extractions; and in-oil gas concentration calculating which calculates in-oil gas concentrations of the gas components on the basis of the extracted-gas concentrations thus stored in the extracted-gas concentration storing.
