Abstract :
A fluorescent optical fiber made of Na2O-CaO-5SiO2 glass doped with Sm3+ which absorbs light and then emits a longer-wavelength light is discussed. The sensor can capture light from a light source even though its aperture is not directed toward the source. This property is useful for detecting light from an unfixed light source, such as in cases of electric discharge. An electric-discharge sensor utilizing this fiber has been constructed and successfully applied to the detection of electric discharges in a test device similar to a section of a gas-insulated substation (GIS)
