Oil-filled cable surveillance system using newly developed optical fiber gas sensor

A new surveillance system for oil-filled power cables, which can provide continuous monitoring using a newly developed optical gas sensor that can detect the concentration of the gas dissolved in the oil with extremely high sensitivity, has been developed. It was proved that the degree of deterioration of the insulating oil can be detected by measuring C/sub 2/H/sub 2/ and CH/sub 4/ by investigati...
