These devices or components may be affected by various internal and external factors during continuous operation, such as electrical faults, natural aging of insulation materials, etc., which may induce internal faults. In order to effectively identify and prevent these potential fault risks, monitoring the dissolved gases in the oil of the equipment, especially the acetylene gas, is particularly crucial.
