To detect a disorder in an apparatus regardless of use of environment-friendly and low-cost carbon dioxide gas as insulating gas.
In a carbon dioxide gas-insulating power apparatus, a winding 2 configured by winding a wire coated with an insulating coating 2a on its outer peripheral surface and an insulating spacer 4 supporting the winding 2 are contained in a housing 1, and the power apparatus is filled with the carbon dioxide gas 3 as the insulating gas. The insulating spacer 4 is configured such that an outer peripheral surface of an insulating member 4a is covered with a reducing solid material 4b combined with oxygen which is generated together with CO when the carbon dioxide gas 3 is decomposed with discharge generated between it and the winding 2, and a sensor 6 detecting CO is disposed in an insulating gas atmosphere in the housing 1.
