摘要：
As the moisture content over standard in sulfur hexafluoride( SF6) circuit breakers will menace operation of apparatus and grid. Based on the infrared spectrum absorption, a system using absorption type optic fiber for moisture content detection was studied. The system used semiconductor laser as light source and used harmonic measurement to improve the detection sensitivity. The monisture content has a linear relationship with the output signal. The experimental results show that method of spectrum absorption can not only accurately detect moisture content but also fit for on-line detection. (c) 2011 by Elsevier Ltd.
