N2 - We demonstrate an optical fiber based hydrogen sensor to determine the dissolved hydrogen concentration in oil. This is of special interest in the prevention of the malfunction of power transformers, which has a significant social, economic and environmental impact. This malfunction is often related to the aging and degradation of the insulating system of the transformer. Since hydrogen is produced in most of these transformer faults, the change in hydrogen concentration is a marker for this degradation processes. We show that a PTFE-Pd-capped Mg-Ti thin film based fiber optic sensor is able to measure the dissolved hydrogen concentration quantitatively between 5-15 ppm at 21 C, 5-30 ppm at 40 C, 5-130 ppm at 60 C, and 5-1500 ppm at 80 C. Furthermore, we find that the presence of dissolved CH
