| Abstract: | A mathematical model for separating the hydrogen dissolved in transformer oil is developed. An experimental setup is built to measure extremely low hydrogen concentration based on a fiber optic M Z interferometer. By introducing sound wave modulation to the gas cell, all kinds of environmental interference to the interferometer are significantly reduced and the sensitivity of hydrogen concentration measurement is greatly improved. |
