The goal of this collaborative research is to develop a new insight into the fabrication process of so-called**two-cavity Fibre Bragg Grating (2C FBG) sensors employed for direct measurements of strain and temperature**inside high-voltage power generators. The abnormal vibrations and elevated temperatures of such installations**are an indication of a problem that, if not addressed immediately, could lead to significant outage and/or**replacement expenses. Today, FBGs remain the exclusive solution for sensors having to work inside such a**hostile environment of high voltages and strong electromagnetic fields. To address the manufacturing**deficiencies related to the use of hydrogenated fibres for fabrication of 2D FBG, we propose to investigate**photosensitive fibres. A better stability of the photosensitive fibre and the potentially faster cavity writing time**have the potential to yield a better-quality product with tightened variation within the same batch as well as**from batch to batch.

这项合作研究的目标是对所谓的双腔光纤布拉格光栅（2C FBG）传感器的制造过程进行新的了解，该传感器用于直接测量高压发电机内部的应变和温度。此类装置的异常振动和温度升高 ** 表明存在问题，如果不立即解决，可能导致重大停机和/或 ** 更换费用。今天，FBG仍然是传感器的独家解决方案，必须在高压和强电磁场的恶劣环境中工作。为了解决与使用氢化纤维制造2D FBG相关的制造缺陷，我们建议研究光敏纤维。光敏纤维更好的稳定性和可能更快的腔写入时间 ** 有可能生产出质量更好的产品，并且在同一批次内以及 ** 批次之间的变化更严格。
