    • A distributed sensing system for detecting partial electric discharge along the length of an extended object or objects. An optical fiber having a cladding integrated with luminescent material and a silica core of less than 500 micro-meters in diameter with a first reflective end deployed in proximity to test objects. A photo detector is positioned at the second end of the optical sensing fiber and receives and measures both a direct emission light from an electric partial discharge event and the reflected emission light from the reflection end of the optical sensing fiber. The measured signals and their arrival times are used to determine the location and magnitude of a partial electrical discharge.
    • 一种用于沿着扩展对象或物体的长度检测局部放电的分布式感测系统。 一种光纤,其具有与发光材料集成的包层和直径小于500微米的二氧化硅核心,第一反射端部分设置在测试对象附近。 光检测器位于光学感测光纤的第二端,并且接收并测量来自电部分放电事件的直接发射光和来自光学感测光纤的反射端的反射发射光。 测量信号及其到达时间用于确定部分放电的位置和幅度。
