Abstract: In order to improve reliability of the online monitoring devices of dissolved gases in transformer oil in severe cold region and accuracy of the monitoring data, based on the research of state grid, this paper proposed the statistical analysis of application and reliability of the online monitoring devices of dissolved gases in transformer oil on different monitoring principles and analyzed the types of common faults and its reasons. In allusion to common technical combination, combining with the requirement of high reliability and less maintain of online monitoring devices in severe cold region, this paper gave the advice of selecting the online monitoring devices of dissolved gases in transformer oil.
Key words: transformer; dissolved gases in oil; online monitoring device; severe cold region
