Abstract :
A hydrogen sensor for detection of H2 dissolved in transformer oil has been developed for the use in a stand-alone dissolved gas analyzer (DGA) which will also assess the relative humidity saturation of oil. The sensor uses palladium nanoparticles as a sensitive material that is selective to hydrogen. The DGA will be capable of measuring dissolved hydrogen in concentrations from 50 ppm to 4000 ppm.
