Abstract: To provide a system and method for inspecting a state of a transformer without using gas chromatography mass spectrometry every time insulating oil is sampled from the transformer.SOLUTION: An inspection method for an inspection system 1 for a transformer comprises air purification filters 2, 9, a sample container 3, electromagnetic valves A, B, a gas mixing container 4, a smell sensor 5, a pump 6, a device control unit 7, and a maintenance management standard estimation unit 8. The air purification filters remove volatile organic chemicals. The sample container encloses insulating oil sampled from the transformer. The gas mixing container mixes gas discharged from the carrier gas side with gas discharged from the sample container side. Each electromagnetic valve adjusts a valve opening and closing degree according to a valve adjustment command from the device control unit. The pump draws gas from the gas mixing container. The smell sensor outputs a sensor signal corresponding to the gas from the gas mixing container. The maintenance inspection standard estimation unit estimates which section of internal abnormality sections for the transformer the transformer's state corresponds to on the basis of the sensor signal from the smell sensor.SELECTED DRAWING: Figure 1
