Gas sensors for detecting SF6 decomposition products are being actively pursued as low cost instrumentation for detecting and locating faults in GIS. We developed an amperometric solid state ionic sensor using high ionic conductive solid. The sensor responded to the changes in HF concentration ranging from 1 to 10wt.ppm in SF6 gas at 1 atm. The rapid rising current based on the electrode reaction was detected in a few minute and gradually increased toward a stationary state. After purging the sample gas, the output current reduced and returned to the base line.<br>We have revealed that amperometric solid state ionic sensor has strong possibility for detecting SF6 decomposition products and locating faults in GIS.
