摘要

观察变压器油的质量对变压器的健康和系统至关重要。变压器油的老化状态和相应的平均剩余寿命可以通过击穿电压(BDV)测试、紫外-可见(UV-Vis)光谱和折射率(RI)标准方法来确定。本研究的主题是设计和制造一种更简单、低成本、基于倏逝场吸收的光纤传感器(EFA-FOS)，与这些经过验证的标准方法兼容，并通过确定临界电压阈值进行比较性能分析。除了上述昂贵和繁琐的标准方法外，由于在线传感器系统，使用该临界电压值进行预测试，因此可以使用油的可用性。油样的EFA-FOS测量结果可以准确地判断油样的老化程度。样品的RI用EFA-FOS测定，灵敏度为−70 V/RIU，线性度为0.98 (R)。传感器输出和测量的BDV之间也有很强的关系，回归常数为0.86 (R)

Evanescent Field Absorption-Based Fiber Optic Sensor for Detecting Power Transformer Oil Degradation

Observing the transformer oil quality is essential for the transformer’s health and system. The aging state of the transformer oils and the average remaining life accordingly can be determined using the breakdown voltage (BDV) test, ultraviolet-visible (UV-Vis) spectroscopy, and the refractive index (RI) standard methods. The subject of this study is to design and manufacture a much simpler and low-cost, evanescent field absorptionbased fiber optic sensor (EFA-FOS) compatible with these proven standard methods and to perform a comparative performance analysis by determining a critical voltage threshold. Apart from the expensive and cumbersome standard methods mentioned above, the usability of the oil is carried out, thanks to the online sensor system, with the pretest using this critical voltage value. EFA-FOS measurement results of oil samples can determine the samples’ aging degree with high accuracy. The samples’ RI is determined with EFA-FOS with a sensitivity of −70 V/RIU and a linearity of 0.98 (R). A strong relationship has also been determined between the sensor output and measured BDV with a regression constant of 0.86 (R). ARTICLE HISTORY Received 30 April 2021 Accepted 31 October 2021

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
