| Abstract: | This paper introduces structural characteristics and application of dissolved gas-in-oil analyzer of composite con- centration. Combining practical operational and off-line chromatographic analysis data, it analyzes merits and demerits, ve- racity, operational reliability and maintenance cost of the analyzer and draws conclusions for the analyzer such as untimely reflection on fault, incorrect measuring data, being unable to judge fault types, unreasonable communication modes, high fault rate and big maintenance cost. |
