Xu C., Zhao J., Jiang F., 2015, A Hydrogen Gas Concentration Quantitative Detection Technique of Transformer Oil Based on Sound Velocity Measurements, Chemical Engineering Transactions, 46, 253-258.
This paper introduces a quantitative detection technology of hydrogen concentration in transformer oil, which is based on ultrasonic velocity measurements. This detection technique can effectively overcome the influences on final velocity measurement result produced by temperature T, gas adiabatic index ?, number of gas molecules M , and is more suitable for industrial field on-line inspection applications.
