Abstract:
1. An in-oil gas concentration measuring system comprising: gas extracting means for extracting an in-oil gas from an insulating oil sample; component detecting means for detecting gas components of the in-oil gas extracted by the gas extracting means; extracted-gas concentration calculating means for calculating extracted-gas concentrations of the gas components being detected, based on data detected by the component detecting means; extracted-gas concentration storing means for storing information on the extracted-gas concentrations calculated by the extracted-gas concentration calculating means as a result of two or more extractions performed by the gas extracting means, the information being stored in each of the extractions; and in-oil gas concentration calculating means for calculating in-oil gas concentrations of the gas components based on the extracted-gas concentrations stored in the extracted-gas concentration storing means, wherein the in-oil gas concentration calculating means calculates an in-oil gas concentration (Q) by using the following equation (1), where Q denotes an in-oil gas concentration to be calculated, R denotes an extraction rate of an in-oil gas, and X
