Abstract
In a method of diagnosing aged degradation of an oil-filled electrical equipment such as oil-filled power transformers, an amount of organic compounds, other than a combustible gas, dissolved in an insulation oil employed in the equipment is detected. The degree of aged degradation of the equipment is determined based on a result of detection of the amount of organic compounds.
