Transformer Partial Discharge Monitoring Based on Optical Fiber Sensing

然而，力量变压器是高电压力量格子的最重要的设备联机部分分泌物监视的一些传统的方法有一些限制。基于察觉到技术的光纤维的许多优点，我们在察觉到能为联机部分分泌物监视上的变压器是有用的纤维光学 Fabry-Perot (FP ) 上做了一些研究。这研究瞄准了改进监视的力量系统安全的可靠性。我们如下做了一些工作：为纤维光学 FP 传感器准备设计一个集合，根据严格地认出传感器的制造过程，造为察觉到的纤维光学 FP 的一个合理信号解调系统，做关于联机部分分泌物信号监视的初步的分析，与一样的分泌物紧张与一样的测量距离和不同测量距离在不同分泌物紧张上包括研究，然后做试验性的结果的详细分析。

The power transformer is the most important equipment of the high voltage power grid, however, some traditional methods of online partial discharge monitoring have some limitations. Based on many advantages of the optical fiber sensing technology, we have done some research on fiber optics Fabry-Perot （FP） sensing which can be useful for the transformer on online partial discharge monitoring. This research aimed at improving the reliability of power system safety monitoring. We have done some work as follows： designing a set for fiber optics FP sensor preparation, according to the fabrication procedure strictly making out the sensors, building a reasonable signal demodulation system for fiber optics FP sensing, doing a preliminary analysis about online partial discharge signal monitoring, including the research on different discharge intensities with the same measuring distance and different measuring distances with the same discharge intensity, and then making a detailed analysis of the experimental results.
